Here is a basic tutorial for Python, for beginners!
Table of Contents:
1. The developer of python
2. Comments/Hashtags
3. Print and input statements
- f' strings
4. If, Elif, Else statements
5. Common Modules
1. Developer of Python
It was created in the late 1980s by Guido van Rossum in the Netherlands. It was made as a successor to the ABC language, capable interfacing with the Ameoba operating system. It's name is python because when he was thinking about Python, he was also reading, 'Monty Python's Flying Circus'. Guido van Rossum thought that the langauge would need a short, unique name, so he chose Python.

2. Comments/Hastags
Comments are side notes you can write in python. They can be used, as I said before:
- sidenotes
- instructions or steps
- etc.
How to write comments:
#This is a comment
The output is nothing because:
- It is a comment and comments are invisible to the computer
- Comments are not printed in Python
So just to make sure, hastags are used to make comments. And remember, comments are ignored by the computer.
3. Print and Input statements
1. Print Statements
Print statements, printed as print
, are statements used to print sentences or words. So for example:
print("Hello World!")
The output would be:
Hello World!
So you can see that the print
statement is used to print words or sentences.
2. Input Statements
Input statements, printed as input
, are statements used to 'ask'. For example:
input("What is your name?")
The output would be:
What is your name?
However, with inputs
, you can write in them. You can also 'name' the input
. Like this:
name = input("What is your name?")
You could respond by doing this:
What is your name? JBYT27
So pretty much, inputs are used to make a value that you can make later.
Then you could add a if
statement, but lets discuss that later.
3. f strings
f strings, printed as f
(before a qoutation), is used to print or input a value already used. So what I mean is, say I put an f
string on a print statement. Like this:
print(f"")
The output right now, is nothing. You didn't print anything. But say you add this:
print(f"Hello {name}!")
It would work, only if the name
was named. In other words, say you had a input
before and you did this to it:
name = input()
Then the f
string would work. Say for the input, you put in your name. Then when the print statement would print:
Hello (whatever your name was)!
Another way you could do this is with commas. This won't use an f string either. They are also simaler. So how you would print it is like this:
name = input()
...
print("Hello ", name, "!")
The output would be the same as well! The commas seperate the 2 strings and they add the name inside. But JBYT27, why not a plus sign? Well, this question you would have to ask Guido van Rossum, but I guess I can answer it a bit. It's really the python syntax. The syntax was made that so when you did a plus sign, not a comma, it would give you an error.
Really, the only time you would use this is to give back your name, or to find if one value was equal to each other, which we'll learn in a sec.
4. If, Elif, Else Statements
1. If Statements
If statements, printed as if
, are literally as they are called, if sentences. They see if a sentence equals or is something to an object, it creates an effect. You could think an if
statement as a cause and effect. An example of a if
statement is:
name = input("What is your name?")
#asking for name
if name == "JBYT27":
print("Hello Administrator!")
The output could be:
What is your name? JBYT27
Hello Administrator!
However, say it isn't JBYT27. This is where the else, elif, try, and except statements comes in!
2. Elif Statements
Elif statements, printed as elif
are pretty much if
statements. It's just that the word else
and if
are combined. So say you wanted to add more if
statements. Then you would do this:
if name == "JBYT27":
print("Hello Administrator!")
elif name == "Code":
print("Hello Code!")
It's just adding more if
statements, just adding a else
to it!
3. Else Statements
Else statments, printed as else
, are like if
and elif
statements. They are used to tell the computer that if something is not that and it's not that, go to this other result. You can use it like this (following up from the other upper code):
if name == "JBYT27":
print("Hello admin!")
elif name == "Squid":
print("Hello Lord Squod!")
else:
print(f"Hello {name}!")
5. Common Modules
Common modules include:
- os
- time
- math
- sys
- replit
- turtle
- tkinter
- random
etc.
So all these modules that I listed, i'll tell you how to use, step by step! ;) But wait, what are modules?
Modules are like packages that are pre-installed in python. You just have to fully install it, which is the module(please correct me if im wrong). So like this code:
import os
...
When you do this, you successfully import the os
module! But wait, what can you do with it? The most common way people use the os
module is to clear the page. By means, it clears the console(the black part) so it makes your screen clear-er. But, since there are many, many, many modules, you can also clear the screen using the replit
module. The code is like this:
import replit
...
replit.clear()
But one amazing thing about this importing is you can make things specific. Like say you only want to import pi
and sqrt
from the math
package. This is the code:
from math import pi, sqrt
Let me mention that when you do this, never, ever add an and. Like from ... import ... and ...
. That is just horrible and stupid and... Just don't do it :)
Next is the time
module
You can use the time module for:
- time delay
- scroll text
And yeah, that's pretty much it (i think)
Note:
All of the import syntax is the same except for the names
Next is tkinter, turtle
You can use the tkinter
module for GUI's (screen playing), you can import it in a normal python, or you can do this in a new repl.
You can use the turtle for drawing, it isn't used much for web developing though.
The math and sys
The math is used for math calculations, to calculate math. The sys is used for accessing used variables. I don't really know how I could explain it to you, but for more, click here
Random
The random
module is used for randomizing variables and strings. Say you wanted to randomize a list. Here would be the code:
import random
...
a_list = ["JBYT27","pie","cat","dog"]
...
random.choice(a_list)
The output would be a random choice from the variable/list. So it could be pie, JBYT27, cat, or dog. From the random module, there are many things you can import, but the most common are:
- choice
- randrange
etc.
And that's all for modules. If you want links, click below.

I hope you enjoyed this tutorial! I'll cya on the next post!
stay safe!
thats nice
me who knew all of it but still is new to python
Thanks! lol @Z3FFY
@JBYT27 wow you replied within 2 minutes
xD ;) @Z3FFY
thanks dude, i am pro at python now :D
np! yay! :D @ETICHUR2018
coder100 likes to lurk
This is a good tutorial thx for this :D
Hum ok pretty decent tutorial, some tips:
for comments, you can also have multiple line comments:
"""
multiple
lines
yay
"""
- If and Else Statements
elif...?
- Common Modules
Common modules include:
os
time
math
sys
replit
turtle
tkinter
etc.
never heard of the "etc."
module lol
The most common way people use the os package is to clear the page.
how?
whateveryouwanttoputhere = input("What is your name?")
pretty long variable, not really recommended..
you can also clear the screen using the replit package
how? examples?
and the random module (randint
, randrange
, choice
)?
and you should prolly include more examples, especially on the modules. also what about variables? for loops? while loops? lists? you're spending a bit more time on the modules than other python ueufl things tbh..
but thank for ping I guess. Maybe try adding some more things to the tutorial, but otherwise, nice start! :D
Ok, thx for the suggestion! Its my first tutorial too, so im prob gonna be bad, lol @Bookie0
@JBYT27 cool np! :D
(^‿^) @JBYT27
Elipie said I couldn't fix too much, but later on a different tutorial, i'll do what you said! :) Thanks btw! @Bookie0
@JBYT27 wdym? you can and should always try ti fix things ig :)
@Bookie0, ik, but bc it's a submission... ima make a editted v. later ;)
@JBYT27 hum well ok then, ig you could say that what you edit isn't part of the submission, but if you make another post edited, make sure to edit/add many more things, so that it's not just almost the same thing!〤◕‿◕〤
got it! @Bookie0
cool! ¬‿¬ @JBYT27
import replit
import os
os.system("clear") #clears the screen
replit.clear() #clears the screen again
@InvisibleOne but os.system('clear')
can be used not only on the repl.it IDE i think
Yeah, it doesn't work on my other IDE's @Bookie0
@InvisibleOne ya, tis why os.system('clear')
superior lol :)
great tutorial thanks mate
Thanks! Np! @JWZ6
Really helped for a beginner like me. Can’t make much with it, but it’s a great start. Thanks JBYT27!
NP! glad it helped! Yeah, im making an edited version of it, i hope you see it later! @hen0tic02
Thanks, it really helped since it was well explained and I'm new to coding. Let me know where to start off since youtube videos are like 4 hrs+ and they don't really explain what they do.
Oh, ok glad I helped @ItzMalakai
How does this only have 23 votes? (24 including mine (: )
lol, thx! I hope you learned something! @ThatOneGuy1234
Thanks for this tutorial. Will be looking forward for further tutorials. :)
Np! Yep! @AnshumaanBajpai
A nice, structured and concise tutorial. I recommend changing this part though so as to avoid confusion;
The output would be a random choice from the variable/list. So it could be pie, JBYT27, cat, or dog. From the random module, there are many things you can import, but the most common are:
- choice
- range
etc.
I recommend changing the range to randrange, syntax: randrange(start, stop, step)
, since randrange()
is the module included in the 'random' library which will create a list of integers and return a random number from said list, whereas the range function, syntax: range(start, stop, step)
, is a built-in function that only creates a list of integers in a given range, commonly used in for loops as an Iterator
ah, ok. Thanks for the suggestion! @StevenVoronko
This is great!
thanks! @riparino
Thanks!
np! glad i helped! @YazCar
#this was helpful
:D glad it was! @cynthiawachira
thats great tutorial for beginners. It's well explained. Waiting for your next tutorials. Also check"https://favtutor.com/blog-details/7-Python-Projects-For-Beginners" for python beginners project. It's also very helpful. Hope you like it.
Thanks! i'll look at the tutorial! @billypeterson
lua is pretty similar to python, thanks for the tutorial tho!
oh, i didn't know that! thanks for letting me know! Np! @Andromida
thanks! this is really handy since im a beginner. thanks once again :D
np! glad you learned something! @heavyduck
thank u very much i have also posted a simple addition program pls see it
Thanks! Glad I helped! Ok, sure! @pyashika
u know when i use the if statements then how comes when i use the hashtag it doesnt turn green
the green you can just ignore. it only happens usually with complexity stuff and module stuff. @BoyAhmed
@JBYT27 so i dont have to do the green part?
@BoyAhmed and thanks for replying so fast i really appreciate it
:)
Yeah. lol, np! glad you learned something! @BoyAhmed
Thank you, this helped a lot, I was completely lost at first but this described everything very well :D
Np! I’m glad I helped! @LeliaByerley
thank you. i appreciate this totorial.
Np! Thanks! @bowmand117
@JBYT27 ur welcome. i thought this was for javascript for a sec and tried coding with it then realized it was for python XD
XD hope u learned something! @bowmand117
@JBYT27 i did. before this, i only knew block coding on https://www.scratch.mit.edu, and even then i wasnt that good.
cool! Glad you learned somethin! Check out the other python tutorial links as well, they are much better than mine, lol @bowmand117
You CAN use pluses, but you can't put strings and ints together, but also you can make ints strings w/ the str() funcion by putting a int into the funcion like this, str(5[it can be any int]) this outputs this, 5, or, "5"
Oh, ok. Thx for the tip! @catspython
@JBYT27 Your welcome, I didn't know that you can use commas, nor that f-strings even existed!
Lol, glad I helped as well! @catspython
Ok, going to be hones haven't read it all because very simple but it looks very good! I
lol, thanks! @OlauPla
nice, ima judge this
1 question, could I edit this a bit? @elipie
@JBYT27 uh, only a bit, i already judged it :)
@JBloves27 idk i was just doing it
lol, ok @ETICHUR2018
when you say to put imput ("wath is your name") it is not good because its mark is wrong so you have to print my instead
Ah, ok. Ill put that on my next edited tutorial! @lperras
Do you teach more ?
I will on my next tutorial! ;) @SkullFire
posting a comment to save this, thank you very much!!!!!!!!!!!!!!!!! :D youre a godsend
Np! Lol, thanks! Glad you like it so much! :D @heavyduck
