Python break statement, just like in C language, breaks the minimum closure for Or while loop.

The break statement is used to terminate the loop statement. That is, if the loop condition does not have a False condition or the sequence has not been completely recursed, the execution of the loop statement will also be stopped.

The break statement is used in while and for loops.

If you use nested loops, the break statement will stop execution of the deepest loop and start execution of the next line of code.

Python language break statement syntax:

break

Flow chart:

Example (Python 2.0)

#!/usr/bin/python
# -*- coding: UTF-8 -*-
for letter in 'Python':     # 第一个实例
   if letter == 'h':      
        break
   print '当前字母 :', letter
var = 10                    # 第二个实例
while var > 0:              
   print '当前变量值 :', var
   var = var -1
   if var == 5:   # 当变量 var 等于 5 时退出循环
      break
print "Good bye!"

Execution results of the above examples:

当前字母 : P
当前字母 : y
当前字母 : t
当前变量值 : 10
当前变量值 : 9
当前变量值 : 8
当前变量值 : 7
当前变量值 : 6
Good bye!
