A simple code snippet that use reflection to print names of attributes, methods and doc strings:
class Obj:
""" An object that use reflection """
def __init__(self,name):
""" the constructor of this object """
self.name = name
def print_methods(self):
""" print all the methods of this object and their doc string"""
print '\n* Methods *'
for names in dir(self):
attr = getattr(self,names)
if callable(attr):
print names,':',attr.__doc__
def print_attributes(self):
""" print all the attributes of this object and their value """
print '* Attributes *'
for names in dir(self):
attr = getattr(self,names)
if not callable(attr):
print names,':',attr
def print_all(self):
""" calls all the methods of this object """
for names in dir(self):
attr = getattr(self,names)
if callable(attr) and names != 'print_all' and names != '__init__':
attr() # calling the method
o = Obj('the my object')
o.print_all()
Which gives the following output:
* Attributes *
__doc__ : An object that use reflection
__module__ : __main__
name : the my object
* Methods *
__init__ : the constructor of this object
print_all : calls all the methods of this object
print_my_attributes : print all the attributes of this object
print_my_methods : print all the methods of this object
