Hello hello hello wassup people,
I’m just going to show you some quick things to make your Python code cool!
1) Screen Clearing
Screen clearing is very useful; you use it to, well, clear the screen. I like it a lot because you can use it to erase everything so that it looks better, and so that not too much text crowds the screen!
For the screen clearing, you need to just:
You can copy this code and put it every time you need to.
However, i prefer to create a function, so that i dont need to keep putting that (even if its just a few letters...):
def sc(): os.system(‘clear’)
As you can see I called the function
sc(),which stands for screen clear, so each time I want to clear the screen, i just call that function. It makes it just a bit shorter.
(Thanks to @ArjunSS1 for helping me with the screen clear)
2) Typewriter effect
Now this typewriter effect is super cool, because it makes the text print one letter at the time. You can regulate it so that it prints the text fast or slow.
First the imports:
import sys, os, curses from time import sleep
And this is the code:
st = 0.04 def sp(str): for letter in str: sys.stdout.write(letter) sys.stdout.flush() time.sleep(st) print()
I usually put it at
0.04because it prints it not too fast and not too slow. But you can change it. Just change the value after
Each time you want to do this typewriter effect, just do:
3) While loops to go back to menu (very basic)
Personally, I’m not a pro in loops, but this is what I do sometimes. Imagine you want to do sort of menu option, like this:
print (“This is the menu”) action1 = input(“Type hello for some greetings > ”) if action1 == “hello”: print(“Hola”) print(“Bonjour”) print(“Aloha”)
So when the user types hello, several greetings will appear. But what if the user types something else by accident? Then, you could add an else statement, and saying something like “invalid”, and then the user could return to the menu,
This is how you do that:
back_to_menu = True while back_to_menu == True: print (“This is the menu”) action1 = input(“Type “hello” for some greetings > ”) if action1 == “hello”: print (“Hola”) print (“Bonjour”) print (“Aloha”) else: print (“You wrote something else than “hello”! ”) back_to_menu = True
So when you put
back_to_menu = True at the end of the
else statement, the user will arrive back at the menu!
This is how to make colors in Python.
Pretty simple, just copy paste these colors (because typing them would be to long...)
# colors black = "\033[0;30m" red = "\033[0;31m" green = "\033[0;32m" yellow = "\033[0;33m" blue = "\033[0;34m" magenta = "\033[0;35m" cyan = "\033[0;36m" white = "\033[0;37m" bright_black = "\033[0;90m" bright_red = "\033[0;91m" bright_green = "\033[0;92m" bright_yellow = "\033[0;93m" bright_blue = "\033[0;94m" bright_magenta = "\033[0;95m" bright_cyan = "\033[0;96m" bright_white = "\033[0;97m"
So to use it, just put the color before the text:
print(bright_yellow + “text here”)
This also works with the
slowPrintI mentioned earlier
So that’s about it i know this tutorial isn’t very good, but upvote if it helped you or if you like it.
Lastly, nothing is under copyright, so go on and copy paste!

\033[39m ends any ANSI escape code
means you can do any rgb color
underlines text and
you can do
import re self.removeAnsi = re.compile(r'\x1B(?:[@-Z\\-_]|\[[0-?]*[ -/]*[@-~])') print(self.removeAnsi.sub('', green+"hi"))
to remove ansi codes (for if you are doing len() with variables that have color etc)
you can make colors accessable from all functions like this
def func1(): print(colors.black+"hi") def func2(): print(colors.red+"hi") class colors(): black = "\033[0;30m" red = "\033[0;31m" ... func1() func2()
is a usefull link for ansi escape codes, but quite a few dont work with the console
alternate way of clearing screen
also personally i prefer doing
to clear the screen as it is less flicker than
V this prints alot but doesnt flicker much (it also uses spacing1 but we arnt there yet)
end=x on print statements
wont create a new line
will print "cathello" or "doghello"
3 variations on spacing for menus
for printing menus these can be usefull
def spacing1(length,a,b): removeAnsi = re.compile(r'\x1B(?:[@-Z\\-_]|\[[0-?]*[ -/]*[@-~])') a=str(a) b=str(b) return a+(" "*(length-(len(removeAnsi.sub('',a))+len(removeAnsi.sub('',b))))+b) def spacing2(length,a,b): a=str(a) b=str(b) return a+(" "*(length-(len(a)+len(b)))+b) def spacing3(length,a,b,c): a=str(a) b=str(b) return a+(c*(length-(len(a)+len(b)))+b)
will output (in red for the first value and blue for the second)
hi hello cat dog
as you can see they maintain a legnth of 10
is the same but it doesnt work with ansi for simplicity
but you can do
to print in one single color
hi hello cat____dog
on the type writer effect
personally i find it annoying, add an option to remove it on the main menu if you use it
classes (better global variables)
class hi(): def __init__(self): #this is called when the class is initiated self.var="hello" def hello(self): print(self.var) self.hi("cat") def hi(self,text): print(self.var+" "+self.hi) example=hi() example.hello()
hello hello cat
multiple of the same class can exist at the same time like this
any variables that change based of input will be seperate to eachover, self.var in example1 can have a different value to self.var in example2
