Python Exercise 25

The Python language allows you to embed another loop inside a loop body.

Python for loop nesting syntax:

For in sequence: For in sequence: statements(s) statements (s)              

Python while loop nesting syntax:

While expression: While    expression: statement(s) statement  (s)             

You can embed another loop body in the loop, such as a For loop in the while loop, and conversely, you can embed a while loop in a for loop.

The following instance uses the prime number between the nested loop output 2~100:

#!/usr/bin/python#-*-Coding:utf-8-*-I= 2While(I< 100):J= 2 While(J<= (I/J)): If Not(I%J): break J = J + 1 if   (j > I /j)  :print I,  "is prime"  I = I + 1< Span class= "PLN" >print  "good bye!"
