swap numbers in python without using third variable code example

Example 1: swap variables in python

a = 5
b = 6
# now swp the variables
a, b = b, a
# to swap two variables you need an other string harder than the first one
c = a	# 5
a = b	# 6
b = c	# 5

Example 2: python swap numbers

# Swap without using any temp variable
x = 66
y = 77 

print("Original: ", x,y)

x = x - y
y = x + y
x = y - x 

print("Swapped 1st time: ", x,y)

x = x + y
y = x - y
x = x - y 

print("Swapped 2nd time: ", x,y)

# Output:
# Original:  66 77
# Swapped 1st time:  77 66
# Swapped 2nd time:  66 77
