嵌入式 pyhton中的判断语句

本文主要是介绍嵌入式 pyhton中的判断语句，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

在Python中比较语句和其它的一样都是用if来做判断的，只是语法上后面会带上冒号，如ifa>b:,相当于if（a>b）{}.

同样你可以判断函数的返回值为True或者False来做判断

[python] viewplain copy print ?

Console OutPut:

[c-sharp] viewplain copy print ?

多重比较：

当然你可能会用到且或这些操作，在Python中是使用and/or 来做到的，看代码吧，从代码中学习语言才是王道:

[python]viewplaincopyprint?

__author__="Alex"
__date__ ="$2011-2-17 10:39:27$"
if __name__ == "__main__":
print "Hello";
if 4 > 3 and 6 > 3: print('You are right , 4 is greater than 3 and 6 is greater than 3 too') # will print, True and True becomes True
if 4 > 3 and 2 > 3: print('...') # will not print, True and False becomes False
if 4 > 3 and not 2 > 3: print('You are right , 4 is greater than 3 and 2 is less than 3 ') # will print, True and not False becomes True
if 4 > 3 or 6 > 3: print('You are right...,When 4 is grater than 3 is ture, the condition is ture') # will print, True or True becomes True
if (4 > 3 and 6 > 3) and not ( 3 > 5 or 3 > 7): print("(True and True) and not ( False or False ) becomes True and not False")#Complex Multiple Conditions
