a = 5
def fun(b):
global a
a = 5
print(a, b) # 5, 5
print (a is b) # True
def foo(b):
global a
a = 6
print(a, b) # 6, 5
print (a is b) # False
fun(a)
foo(a)
So, I'm learning python and was playing around with identity/references. As per this link, identity of object never changes once it is created.
Why does the identity change when assigning a different value to variable a that is already created? Why assignment has different behavior in the two functions?
