I got tricked into reading Zed Shaw to learn python

His explanations are all a bit weird and since I started the book I've heard he's a bit of a meme. It also seems a bit too simple for me personally. But whatever, I'm halfway through so I might as well finish.

Here's some code he writes for one of the examples:

def bear_room():
    print ”There is a bear here.”
    print ”The bear has a bunch of honey.”
    print ”The fat bear is in front of another door.”
    print ”How are you going to move the bear?”
    bear_moved = False

    while True:
        choice = raw_input(”> ”)

        if choice == ”take honey”:
            dead(”The bear looks at you then slaps your face off.”)
        elif choice == ”taunt bear” and not bear_moved:
            print ”The bear has moved from the door. You can go through it now.”
            bear_moved = True
        elif choice == ”taunt bear” and bear_moved:
            dead(”The bear gets pissed off and chews your leg off.”)
        elif choice == ”open door” and bear_moved:
            gold_room()
        else:
            print ”I got no idea what that means.”

He's not explained "while True" very well, just said that it results in an infinite loop, which is a pretty obvious, useless and tautological explanation.

I have a question about it. In python, does a function call cause the infinite loop to break then? Typically I'd be used to a break; after the function calls in order to exit the loop.

Basically I don't quite understand how the infinite loop is being broken, and he's not explained it anywhere. My limited knowledge of programming tells me that infinite loops are dangerous and need to be properly exited with a break or something that causes a break.

What breaks an infinite loop in python? And what specifically is breaking the loop here? The function calls? It seems weird that a function call would break a loop without "break" being explicitly stated.

>>59314870
Python has a break statement that works the same way it would in C.

Most likely, the program stops when dead() is called, but to be sure of that, you would have to look what's inside the dead() function.

"Oh, downloading a file via PS is simple, it's just"

 $client = new-object System.Net.WebClient
$client.DownloadFile("http://www.xyz.net/file.txt","C:\tmp\file.txt") 

What the fuck is this, maybe I should just download wget for windows?
"Count to 10:"

 PS> for($i=1; $i -le 10; $i++){Write-Host $i} 

Eh... I feel like downloading files manually could be faster at this point.
And "-le" is a comparison because "<=" is atrocious to type in command line, apparently.

>>59314924

Yeah, dead() just prints a message and calls python's exit().

Say gold_room() is called from within the loop. His intention is to confine each "room" of the game to a function. So the gold_room() function runs and waits for whatever input is required there and call whatever function is going to be called from the gold room.

But seeing as the while loop was never broken, is it still running? Did we move outside of the scope of the bear_room function by moving to a different function thus the loop is destroyed automatically?

I don't really understand why there's no break.

>>59314870
>What breaks an infinite loop in python?
A break or return statement. Or something that removes control from the application (i.e., os.exit or an uncaught exception).

> And what specifically is breaking the loop here?
Depends on what `dead' and `gold_room' does.

>>59314982
>Did we move outside of the scope of the bear_room function by moving to a different function ...
yes
> ... thus the loop is destroyed automatically?
no

The loop resumes when gold_room returns.

>>59314964
i fucking hate powershell.

today i wanted to make a script that would upload a 2 byte file to an ftp server. it's like 20 lines and the syntax is so inconsistent it makes me cringe. i should have just used the first suggestion on stackexchange to just use the ftp cmd line program but i wanted to do it the Right Way

>>59314994
Can't do things in a convinient way without 3rd party software? Yeah, probably.

for($i=1; $i -le 10; $i++){$client.DownloadFile("http://xy.z/"+$i+".jpg","D:\file"+$i+".jpg"}

From what I understood this code should download 10 files from xy.z, and do it, like, xy.z/1.jpg to D:\file1.jpg.

>>59314995

gold_room() "goes" to a different room and carries on with the game from there, just printing text and giving the user the option to move to a different room by calling its function.

Is it enough that exit() is called in the program somewhere eventually? Even if we were calling bear_room, calling gold_room from inside, then calling bear_room again, then gold_room, then some other *_room, then doing a whole bunch of other shit. Provided we eventually meet an exit(), shit's not going to cause memory issues?

>>59314982
Function calls are stacked, so when the callee returns, control is given back to the caller, right after the function call.

>>59315026
Regarding the memory issue, that obviously depends on how many function calls are made.

For example something like

def f(n):
    if n == 1000:
        exit(0)
    f(n + 1)

f(0)

Would probably crash with some like 'Max recursion depth' or whatever, because it makes to many function calls before reaching the condition where it exits.

Functions normally works as >>59315034 describes. Calling 'exit' breaks this by simply stopping. So does raising an exception for that matter.

>>59314870
>>59314982
>>59315026

I think the problem is that you seem to have a newbie/bad understanding of a different OOP language -- likely C++ -- before you started on Python?

This, plus the way the book has presented each function as an "object" in the game, is causing you to try to think like an OOP programmer, except you don't understand OOP properly yet and you're not dealing with OOP code right now. So stop.

The program you're dealing with is simple and very procedural. You can consider the loop as having "paused" whenever a function is called, because at that point the computer is going to that procedure(function) and doing whatever is there before going back to carry on the loop. If it never comes back, that's fine - sure there's probably an issue with stack optimisation there eventually but that's not something you have to worry about - the computer is happily just doing whatever is handed to it at that moment, the loop doesn't continue looping until the function it has called returns, if it never returns, and the program instead exits via sys.exit() or something, that's fine too.

>>59315020
Everything went better than expected and this code works. Despite having cringy syntax.

>>59315104

Could I overcome the stack depth issue by putting a break in the loop myself then?

>>59315166
There's probably no issue, if your functions return. When a function returns, its 'context' is removed from the stack.

The problem in >>59315081 is that the function only stops (if you replaced exit(0) with return, the same crash would still happen) after 1000 calls. At that point, you'd have 1000 times whatever size f requires lying on the stack, which is to much for python.

Something like

def f(n):
    if n == 1000:
        exit(0)

i = 0
while True:
    f(i)
    i = i + 1

would not be a problem as f returns before the next call to f is made.

>>59315166

No, because where would you put the break?

Say you do this:

        elif choice == ”open door” and bear_moved:
            break
            gold_room()

Then you never call gold_room(), the game "goes" nowhere.

Otherwise, if you did this:

        elif choice == ”open door” and bear_moved:
            gold_room()
            break

Then yes, the loop breaks after gold_room() returns, but:

If gold_room() isn't written with a return, and is instead written to sys.exit(), the program exits anyway.

If gold_room() is isn't written with a return, and is instead written to call another function from itself - because I imagine each "room" in this game has its own function, and all the game does is switch rooms by calling another rooms function - then one of those functions will eventually result in sys.exit(), surely, or the game will carry on forever.

If gold_room() is written to return, then gold_room returns, and the player should be "back" in the bear_room(), and should be again presented with the same options as before. But if the break is there, then that doesn't happen. The program goes nowhere again.

Point is, its written correctly for its purpose, at least as far as I can infer.

You can't call functions inside functions without increasing stack depth. That's true regardless of you using while True or not. Stack depth isn't an "issue" either, its normal for programs to increase stack depth, that's why the stack exists.

Stack depth only really becomes an issue in programs that are calling recursive functions repeatedly when the program is designed to be highly optimised. Or when Stack depth is being increased for no reason due to an error in the program's logic.

This code is fine.

Too lazy to read your code, but here's what I'd do.

You only need to think in terms of outer "layer" or border of the matrix. First you draw the outer border of 4x4 matrix, starting at 0,0 with value 1. Then you draw the outer border of a 2x2 matrix, starting at 1,1 with value 13. Hope I explained myself clearly.

Rust is shit, plain and simple. If it wasn't so shit, everyone would be writing everything in it. But only dying Mozilla with pathetic 10% market share is writing in Rust and others choose to stay away from it, which is somehow telling.

>>59317080

You can't have a closed source language but a closed source implementation. Examples are Intel's icc and Oracles JDK. As long as the specs for a language are out (aka it's usable by the public) nothing stops anyone from writing a compiler or interpreter for it.

I think you don't understand what a meme is anon

Rust is a meme in the same way Gentoo is a meme

Its a meme to talk about it, to tell people to use it, to pretend you use it. Its more of a meme to actually use it because you fell for the meme.

Its pretty common for /g/ to say lots of stuff about technical stuff that isn't true or is just baseless opinions because other people are saying it and they think its funny to say it too. Rust is one of those things. Its a meme.

What about memes aren't you understanding?

A programming language cannot be a "meme". There can be memes about doing something with the language, but the programming language itself can't possibly be a meme. You have to be a brain-dead plebbitor to believe otherwise.

You could show me an infinite list of languages based on memes and it wouldn't change anything.
Something which is a programming language is by definition not a "meme".

How do you organize C++ code if your style is a mix of functional and OOP, to make it look more professional?

>>59317442
I hate C, but let's dispel with the myth monads are a make-or-break language feature.

>>59317684
Turn your functional code into either:
- functors overloading the () operator of a class (super pro)
- object methods (poo-in-loo pro)
- static methods of class (quite pro)
- namespace functions (less pro, C-tier)

I just recently read the Linux kernel coding style
https://github.com/torvalds/linux/blob/master/Documentation/process/coding-style.rst
One thing I don't understand is his take on typedefing. Why is it bad to remove the struct/enum/union prefix from every single type? Those are needlessly verbose.

>>59320443
>Why is it bad to remove the struct/enum/union prefix from every single type?
They never said every single type, in fact, they have very clear rules when it is ok to typedef.
>Those are needlessly verbose
Look at the example they are giving, it's pretty clear it's not needless.

>>59320443
>>59321910
Another example would be the win32 api,
INT is

typedef int INT;

what is INT_PTR, here's a hint, it's not a pointer?

So, to avoid shit like this, they just say, unless your code matches a few special cases, don't typedef.
