What do you guys think about this syntax I came up with?
posted to Ask by eekboi

To me, it just looks like you've thrown together words related to the thing you're doing. I can't see any consistent structure or logic behind it.

As an example of some of the inconsistencies, your sample code contains:

  is this or "Binary standard" the part that tells it to encode as binary?

  where does the :/ come from?

</read Input>>>
  why 3 >s?

</display user input/>
  don't we already have Output and Say? (why are there 2?)
  and why is there a / at the end?
  is that just a comment? if so, it should look less similar to code

</web?URL/display ... 
  what does ? do?
  and why is there no closing > ?

"https://{input}.<"com", "net", "web", "org">"
  is this just an entirely different usage of <> ?

<Say, ("click me!") ...>
  why no / at the start?
  is this another different usage of <> ?

  as far as i can tell this is some kind of function
  but the Say function (is Say a function?) works completely differently

  missing the / again?

  why are these only sometimes capitalized?
  (that's not technically syntax, but still)

<"NORTH", "EAST", ...>
  is this the same as <"com", "net", "web", "org">?
  and why are they lowercase later?



  it didn't have / before

Your sanitize function doesn't work when given a string like <script

Servers shut down if 30 minutes pass without them being pinged, so you can work around this with a website like Uptime Robot that will ping your website periodically.

Is there any way to run this "one-liner" inside a while loop, in one line
posted to Ask by rafrafraf

You could move the print(...) if ... else print(...) into a lambda, then call it on input(...) to remove the semicolon. Removing the with statement is harder, but you can do it with this monstrosity I just wrote up:

type(lambda: 1)(type((lambda: 1).__code__)(1, 0, 1, 6, 67, b'y\n|\x00\x83\x00\x01\x00W\x00n\x0c\x01\x00\x01\x00\x01\x00Y\x00n\x02X\x00d\x00S\x00', (None,), (), ("cb",), "", "", 0, b"\xff\xff"),{})(lambda: "replace this part with your code")

EDIT: or this one, which doesn't rely on CPython's implementation details:

(lambda cb, asyncio=__import__("asyncio"): asyncio.get_event_loop().run_until_complete(asyncio.gather(asyncio.coroutine(lambda: (cb(), (e for e in []))[1])(), return_exceptions=True)))(lambda: "replace this")

Or this:

(lambda cb: __import__("concurrent.futures").futures.ThreadPoolExecutor(1).submit(cb).exception())(lambda: "replace this")

Once you've done that, you can just wrap the whole thing in a while loop.

Screen flickering happens when your program output gets split up and doesn't all arrive in your browser at the same time. To force it to be sent all at once, you can use code like this.

takin' a crack at cryptography
posted to Share by Rivase17

A few comments about code style:

  • function and variable names should be snake_case, not camelCase
  • no space after print in print ("stuff")

Code structure:

  • instead of having security, generatePassphrase, etc. print results, return them so you can store the results in a variable and re-use them later.
  • you don't need a reverse function, you can just use "abc"[::-1]

Other things:

  • Caesar cipher, not cesar cipher
  • Your passphrase generator should probably use cryptographically secure random numbers. Look into the secrets module

Language “sight range”?
posted to Ask by Highwayman

Can you know something's address?

In Python, you will almost never have to deal with memory addresses, but if you need to you can use the ctypes module to get an address (it can also do a few other things that C++ can).

Can you know their type?

Variables are dynamically typed, but you can get the type of an object with the type(obj) function.
For example, type(1) == int.

Can you know their size?

Again, you won't need to, but if you want to know, sys.getsizeof(obj) will find the size of an object (not counting things like elements of an array, see here)

And finally how does type casting work in Python.

Python doesn't have type casting in the same way C++ does. int(obj) just passes obj to int's constructor, which is able to convert types (it can also do user-defined conversions if obj has a __int__ method)

repl.it runs Linux, not Windows, so Windows modules like win32com don't work. Also, repl.it does not currently support playing sound, so if you want to run this code, you'll have to do it on your own computer.

When you import main, that re-runs the main.py file, including all your game code. To fix this, you could pass the things you need as arguments, or move card_chooser into main.py.
