Examples of variable exchange in Python

Python's pursuit of brevity, the emergence of a number of operational assignment rules, and strive to be simple, including two or more variable exchange values.
In common language
Copy the Code code as follows:

# declaring variables
A=50
b=10
# Start swapping, assign one of the values to a temporary variable before implementing the swap variable.
TMP = a
A = b
b = tmp

In Python, it is convenient to exchange two variable values
Copy the Code code as follows:

# declaring variables
A=50
b=10
# Start Swapping variables
A, B = b,a

Even multiple variables can be exchanged simultaneously
Copy the Code code as follows:

A=50
b=10
C=20
C,b,a = A,b,c

An operator will take care of multiple variable value swaps!
