python program to swap two numbers code example

Example 1: python swap numbers

x, y = 10, 20
print(x, y) 	# 10 20
x, y = y, x 
print(x, y) 	# 20 10

Example 2: swapping in python

x = 5
y = 10

x, y = y, x
print("x =", x)
print("y =", y)

Example 3: code to swap in python

a=5
b=10
a,b=b,a  #swapped

Example 4: 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
