Examples of variable exchange in Python _python

Python's pursuit of simplicity, the birth of a number of operational assignment rules, and strive to simple, including two or more variable exchange values.
In common language

Copy Code code as follows:

# declaring variables
A=50
b=10
# To start swapping, assign one of the values to a temporary variable before the Exchange variable can be implemented.
TMP = a
A = b
b = tmp

In Python, it is convenient to implement two variable value exchanges

Copy Code code as follows:

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

You can even exchange multiple variables at the same time

Copy Code code as follows:

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

An operator can handle multiple variable value swaps!
