python学习：调用其他函数

vim wc.py

 

#!/usr/bin/python

 

def wordCount(s):

    chars = len(s)

    words = len(s.split())

    lines = s.count('\n')

    print lines, words, chars

 

if __name__ == '__main__':

    s = open('/etc/passwd').read()

    wordCount(s)

 

vim 2.py

 

#!/usr/bin/python

 

import wc

 

s = """hello world

python"""

 

wc.wordCount(s)

 

[root@web10 ~]# python 2.py

1 3 18

[root@web10 ~]# python wc.py

24 35 1122

 

既可以调用wc.py, 也可以执行wordCount(s)函数
