[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

#!/usr/bin/python

class classname:
    def mod1(self):
        pass

    def echo(self):
        print "test"

test.py

#!/usr/bin/python

def test():
    clsname = "classname"
    method = "echo"

    obj = __import__(clsname) # import module
    c = getattr(obj,clsname)
    obj = c() # new class
    #print(obj)
    #obj.echo()
    mtd = getattr(obj,method)
    mtd() # call def

if __name__ == '__main__':
   test() 

 

/usr/bin/python test.py
