系统模块介绍

代码：

#!/usr/bin/env python
# encoding: utf-8
import sys
import platform
def a(vale1):
    def b(valeb):
        if valeb > vale1:
            print("%d is pass"%valeb)
        else:
            print("%d is fales"%valeb)
    return b
c = a(60)
d = a(90)
c(59)
c(89)
d(89)
print (platform.python_version())
print (sys.version)
import random
print (random.random())
print (random.randint(1,2))
print (random.randrange(1,10))
