Python conditional statements

Python conditional statements are code blocks that are executed based on the execution results (True or False) of one or more statements.

Python conditional statements syntax

The Python programming language specifies that any non-zero and non-null value is true, and 0 or null is false.

Python conditional statements example

#!/usr/bin/python# -*- coding: UTF-8 -*-
#Example 1: Basic usage of if
flag = Falsename = 'luren'if name == 'python': # Determine whether the variable is 'python'
flag = True #Set the flag to true when the condition is true
Print 'welcome boss' # and output the welcome message
else: print name # Output the variable name when the condition is not true
