efficiently swap in python code example

Example 1: swapping in python

x = 5
y = 10

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

Example 2: 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
