Python if and input

input用于输入流的捕捉:

 

<textarea cols="50" rows="15" name="code" class="python:showcolumns">#!/usr/bin/python # Filename: if.py number = 23 guess = int(raw_input('Enter an integer : ')) if guess == number: print 'Congratulations, you guessed it.' # New block starts here print "(but you do not win any prizes!)" # New block ends here elif guess &lt; number: print 'No, it is a little higher than that' # Another block # You can do whatever you want in a block ... else: print 'No, it is a little lower than that' # you must have guess &gt; number to reach here print 'Done' # This last statement is always executed, after the if statement is executed</textarea> 

 

执行结果:

Enter an integer: 20

No, it is a little higher than that

Enter an integer: 30

No, it is a little lower than that

Enter an integer: 23

Congratulations, you guessed it.

(but you do not win any prizes!)

The while loop is over.

Done
