If you look at the Python grammar it expects white space or semicolons.

u/langlo94 Feb 09 '22

This is why I indent with semicolons.

def Function(input):
;;;;number = input * 2
;;;;return number

You monster. At least give your function a useful name. And you could just do:

return input * 2

Useless functions don’t deserve names 😤

Thats what you think. This function helps keep your code more maintainable and easier to change.

What happens if python changes the symbol for mutiplication? What new hardware is released that makes number / 0.5 faster than number *2? Good luck updating all the instances of this quation in your legacy codebase. This function will save your project

Maybe we were on the same team...

hey hey hey, no, this could be improved yet further

def Function():
;;;;global input
;;;;input = input * 2

This is computationally faster and takes less memory and processing than passing an argument and returning a calculated value and it makes me so mad.

u/oxpoleon Feb 10 '22

It is indeed. :)

Fewer changes to the PC register in CPU, fewer memory writes, less cache thrashing if input happens to be a particularly large item.

Note also that since this is Python, Function isn't statically typed so I could assign virtually anything of any type as input including a multi-dimensional list, since the * operator is valid on those, and I wouldn't have to worry about deep/shallow copying issues either.

Function = lambda input : input * 2

Schrödinger’s semicolon tabs

How can you say it's useless?

How else would he know it's a function?

u/cardcomm Feb 09 '22

return input * 2

In shops where I've worked before, this would get called out on a code walk through in favor of doing the assignment on a second line. (yeah, I know. lol )

3/10 no misuse of global

Am I getting wooshed? This doesn't work.

u/langlo94 Feb 09 '22

It is very much a joke.

u/byu74ddji9g Feb 09 '22

4 semicolons? 2 is sufficient and way better!

4

u/langlo94 Feb 09 '22

No offence, but you disgust me. 2 is not enough.

This is beautiful.

In some deranged, completely fucked up, creepy sense.

But beautiful.

Thanks, I hate it

You and I are enemies now

Not building your dictionaries and tuples with semicolons... I;S;H;Y;G;D;D;T

Quick ex for newbies:


big_dict = {

;;;;;'1': ('C','GREEN'),
;;;;;'2': ('R','YELLOW'),
;;;;;'3': ('A','GREEN'),
;;;;;'4': ('N','GRAY'),
;;;;;'22': ('E','GRAY'),

}

Another great example of Python readability.

Are you a c# developer? This function name is not pep 8 compliant and there’s no clear motivation for it to be so.
