Python's Assignment Operator: Write Robust Assignments – Real Python
Alright so I saw this and was like "Seriously? An entire article about the assignment operator? This is so dumb, what more could there possibly be to learn about it?" And I must say I was surprised. A lot of it was functionality I didn't realize was afforded to me because of the assignment operator. I assumed it was because of the various objects and their own functionalities so it didn't occur to me that a good portion of it is actually due to the assignment operator as well. I knew a lot of this, but I did learn some new stuff as well. The biggest one in particular is the unpacking operator (*) when doing parallel assignment. Definitely worth reading the article and searching for that. More on reddit.com

I don't understand what you are asking. Your code seems like a classic example of using mutable vs immutable data types. Are you asking if I use return None explicitly? No, I don't. Are you asking if I prefer mutable or immutable? Well that depends on what I'm doing with it. One is not better than the other, they can't be compared like that. More on reddit.com

December 3, 2023What is an assignment operator in Python?
An assignment operator in Python assigns values to variables. The most common is =, which sets the right-hand value to the left-hand variable, helping you store data for later use in your program.

The primary danger of doing something like this is the possibility that (in the second case) some_variable is False but not None (the integer 0, for instance) and you don't want to end up with y equal to None in that case.

r/learnpython on Reddit: Declaring return variables for assignment, no or yes?
December 3, 2023 -
I've been using python for quite some time without formal training. I absolutely love the language. I did C++ at uni decades ago.
So I was taught that you declare your variable initially, and then when you pass your variable to another function or class, then you need to return the result into your variable, else the updates don't reflect.
I'm way too far down the road to ask this now, but heck, why not! What do you guys do?
def x_plus_one(x: int)->int: return x+1
x = 10
x = x_plus_one(x)
print(x) # result = 11
x_plus_one(x)
print(x) # result = 11
from dataclasses import dataclass
def dx_plus_one(dx: Dx)->Dx: dx.x+1 return None
@dataclass class Dx: x: int
xx = Dx(x=10)
dx_plus_one(xx)
print(Dx.x) # result = 11
The dataclass example is a bit lame, I realise...
I know this is not possible for immutable classes like int, tuple, bool or str. But what about for mutable classes like dataframes, dataclasses, dict and list.
What do you prefer? What is the convention? Is explaining the theory worth explaining?
