python swapping two variables code example
Example 1: code to swap in python
a=5
b=10
a,b=b,a #swapped
Example 2: swapping variables in python
a = 1
b = 2
a, b = b, a
# a = 2 , b = 1
Example 3: 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
Example 4: python swap two variables
a = 2
b = 4
print (a) # 2
print (b) # 4
# Now swap them
# Hold one variable in c temporarily:
c = b
b = a
a = c
# Now delete variable c from memory:
del c
print (a) # 4
print (b) # 2
