[Python] python dynamic call module & amp; Class & amp; Method

I always want to know if python is similar to $ classname-> $ method () or call_user_func in php.
Today I have time to check the sample code:
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
 
 
Think in coding
