a, b = b, a?

a =5 b = 6 a, b = b, a print(a) Solution: 6 5, 6 = 6, 5 # i think this is what python is thinking print (a) #a=5. Print 5. So, why did it print six? At whatpoint did a and b switch values? Also, in prior posts people have pointed out the difference between having the same value (5 and 6 here) but be different objects. So super confused here. Thanks for any help:)

a, b = b, a Basically, this is a way of swapping values of variables. a will be assigned value of b and b will be assigned the value of a. Basically, this doesn't work with integers as they have fixed value. They can't change their value.

This thing means swapping the values of the variables.this is not comparing the values of the variables.remember that when we compare values we use double == and when we assign the values to the variable we use single =. a=5 b=6 a,b=b,a Now a become b and b become a.

a = 5 b = 6 a,b = b,a means (a,b) =(6,5)
