How to swap two numbers in Python

There are multiple ways to swap two numbers in Python.

1. Using a temporary variable:

a = 5
b = 7

temp = a
a = b
b = temp

print("a =", a)
print("b =", b)

1. Using tuple unpacking:

a = 5
b = 7

a, b = b, a

print("a =", a)
print("b =", b)

1. Using bitwise XOR operator (not recommended for readability reasons):

a = 5
b = 7

a ^= b
b ^= a
a ^= b

print("a =", a)
print("b =", b)

All three methods produce the same output:

a = 7
b = 5

Note that the second method is the most pythonic and readable way to swap two numbers in Python.
