What's the difference between a, b=0,1 and a=0 b=1 in Python?

Question

It gives me different result when i write it in function

Answer 1

`a = 0 b = 1` being written on the same line wouldn't work. You either write `a = 0` and `b = 1` on different line, or put a semicolon in between, as follows:

`a = 0; b = 1`

Answer 2

if you like to have it in one line, you can do it like that:

a, b = 0, 1
# or
a, b, c, d = 0, 1, 0, 5

it is a positiontional dependensy between left and right side.

Answer 3

a, b = b, a is used with the popular variable switching trick, it would not work with a = b; b = a:
if a = 7, and b = 64.

a, b = b, a ---> a = 64, b = 7
a = b; b = a ---> a = 64, b = 64

I think this is possible because b, a (on right side) is a tuple (tuples does not always need parentheses), whose values can be shared for variables with some special ways.

When the variable values changed it does not change the values in the tuple.
