命令行参数parser模块

通过管道传递

cat  somefile.txt |python somescriot.py |sort

import sys
text = sys.stdin.read()   #标准输入流
words = text.split()
print words

#用户互动
raw_input()
x = input('Enter the first number:')
y = input('Enter the second number:')

参数

判断个数

if len(sys.argv) == 2:
    if sys.argv[1] == "check_hottopic":
        check_hottopic()
    if sys.argv[1] == "check_mongo":
        check_mongo()
    if sys.argv[1] == "check_menhu":
        check_menhu()
    if sys.argv[1] == "check_hotdoc":
        check_hotdoc()
    else:
        print (".........the args must be [check_hottopic,check_mongo,check_menhu,check_hotdoc]. ")
else:
     print (".........the arg have been more than one or no one found in args. ")
