The if statement in Python programming is used to control the execution of the program. The basic form is:

if 判断条件： 执行语句……else： 执行语句……

The judgment condition of the if statement can be > (greater than), < (less than), == (equal to), >= (greater than or equal to), <= (less than or equal to) to express the relationship.

When the judgment condition is multiple values, you can use the following form:

if 判断条件1: 执行语句1……elif 判断条件2: 执行语句2……elif 判断条件3: 执行语句3……else: 执行语句4……

Example

1. Use and for multi-condition judgment:

if name == 'zs' and age == 18:
 
  print('name: zs, age: 18')

2. Use or for multi-condition judgment:

if passwd == '123456' or passwd == 'abcdef'
 
  print('welcome!')

if user == 'zs';
  print('hi zs')
elif user == 'ls':
  print('hi li')
