python swap numbers

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

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 

python swap two numbers

def swap(a, b):
  a = a + b
  b = a - b
  a = a - b
  return a, b

how to swap numbers in python mathematically

def swap_by_temp_var(num1,num2):
    temp = num1
    num1 = num2
    num2 = temp
    return num1, num2
def swap_by_mathamatically(num1,num2):
    num1 = num1 + num2
    num2 = num1-num2
    num1 = num1-num2
    return num1, num2
print(swap_by_temp_var(100,80))
print(swap_by_mathamatically(100,80))
