python入门到精通第三篇--Python 高级语法

1、Python 函数

#!/usr/bin/python

# -*- coding: UTF-8 -*- 

# 定义函数

def printme( str ):

       "打印任何传入的字符串" 

        print str;

         return;

# 调用函数

printme("我要调用用户自定义函数!");

printme("再次调用同一函数");

2、Python 模块

test.py

package_runoob

|-- __init__.py

|-- runoob1.py

|-- runoob2.py

源代码如下：

package_runoob/runoob1.py

#!/usr/bin/python

# -*- coding: UTF-8 -*- 

def runoob1():

  print "I'm in runoob1"

package_runoob/runoob2.py

#!/usr/bin/python

# -*- coding: UTF-8 -*- 

def runoob2():

      print "I'm in runoob2"

在 package_runoob 目录下创建 __init__.py：

package_runoob/__init__.py

#!/usr/bin/python

# -*- coding: UTF-8 -*- 

if __name__ == '__main__':

    print '作为主程序运行'

else:

    print 'package_runoob 初始化'

然后我们在 package_runoob 同级目录下创建 test.py 来调用 package_runoob 包

test.py

#!/usr/bin/python

# -*- coding: UTF-8 -*- 

# 导入 Phone 包

from package_runoob.runoob1 import runoob1

from package_runoob.runoob2 import runoob2 

runoob1()

runoob2()
