At least you are consistent in that you obfuscate every question.
Here's what you seem to want:
import types
def repmeth(self):
print "repmeth"
# inherit from object!
class CC(object):
def __init__(self):
self.m1 = types.MethodType(repmeth, self)
print 'Hello from init'
def m1(self):
print 'm1'
inst = CC()
inst.m1()
Output:
py> import types
py>
py> def repmeth(self):
... print "repmeth"
...
py> # inherit from object!
py> class CC(object):
... def __init__(self):
... self.m1 = types.MethodType(repmeth, self)
... print 'Hello from init'
... def m1(self):
... print 'm1'
...
py> inst = CC()
Hello from init
py> inst.m1()
repmeth
