Now i get why some people are getting it wrong.

This is a List data type so B is typical cloning A while apending 40, 50 to the list
So the output would be [10, 20, 30, 40, 50] for both answers

But if it was a string data type, the option A would execute first and the numbers would remain the same thats [10, 20, 30 ]
While option option B would be updated since its given the += sign by that way the output would be [10, 20, 30, 40, 50] this method would not work if if it not a string data type

Example below with a string data type 👇👇:

a = "hello"

b = a

b += "world"

Print(a)
Print(b)

The output would be:
hello
helloworld

If the above question was a string data typ, then you would receive two separate answers. Buts it's not. Its a LIST

[brandongamingnl]

I tested it. The exact answer will be
a = 10, 20, 30
b = 10, 20, 3040, 50
Yes, 3040 is actually how it will look.

[RevonWalters-pgxz]

Code:

a = [10, 20, 30]
b = a
b += [40, 50]
print(a)
print(b)

Understanding the Behavior

1. a = [10, 20, 30]

Creates a list a with elements [10, 20, 30].



2. b = a

This does not create a new list. Instead, b is just another reference to the same list object as a. Any modifications to b will also affect a.



3. b += [40, 50]

The += operator modifies the existing list in place (it does not create a new list).

This is equivalent to b.extend([40, 50]), which extends the original list.

Since b and a refer to the same list, modifying b also modifies a.



4. print(a) and print(b)

Both a and b refer to the same list, which has been updated to [10, 20, 30, 40, 50].




Output:

[10, 20, 30, 40, 50]
[10, 20, 30, 40, 50]

Key Takeaways:

b = a does not create a copy; it makes b another reference to the same list.

+= modifies the list in place instead of creating a new one.

To create an independent copy, use b = a.copy() or b = a[:].

I thought there would be an error and went into Python to check the exact name but it wasn't there and I didn't know that lists could be combined in this way. Thank you.

[babahavod]

[10, 20, 30, 40, 50]
[10, 20, 30, 40, 50]

Because a and b are the same object, because they refer to the same memory cell

[flxr]

It will be the same, b is just the memory location of a. By editing b you are editing a so the will both be the same

[lossenidoumbia]

a is not updated so it's stay the same
print(a) = [10, 20, 30]
We concatenate b with [40, 50] in b so
print(b) = [10, 20, 30, 40, 50]

[YashTyagi-ngcm]

A, 10, 20, 30, 40, 50
B .10, 20, 30, 40, 50

[sharminakon]

I think that each items of that list (40, 50) will be added to the each items of list b. So the output may be, (40+10+50) = 100, (40+20+50)= 110, (40+30+50)=120. So the full output is
A = [ 10, 20, 30]
B = [100, 110, 120]

[Smiler]

[10, 20, 30]
[10, 20, 30, 40, 50]?

[Refleksifdusunur]

b = a means they share same list in the RAM
so
the result will be [10, 20, 30, 40, 50] for both

if we want to separate them we can use
b = a.copy()

[50, 60, 30]

Am I correct?
