[python]python 动态调用模块&类&方法

一直想知道python里有没有类似php中的 $classname->$method() 或 call_user_func

今天有时间查了一下,示例代码如下:

classname.py

1 #!/usr/bin/python
2 
3 class classname:
4     def mod1(self):
5         pass
6 
7     def echo(self):
8         print "test"

test.py

 1 #!/usr/bin/python
 2 
 3 def test():
 4     clsname = "classname"
 5     method = "echo"
 6 
 7     obj = __import__(clsname) # import module
 8     c = getattr(obj,clsname)
 9     obj = c() # new class
10     #print(obj)
11     #obj.echo()
12     mtd = getattr(obj,method)
13     mtd() # call def
14 
15 if __name__ == '__main__':
16    test() 

 

/usr/bin/python test.py
