I want to avoid calling a lot of isinstance() functions, so I’m looking for a way to get the concrete class name for an instance variable as a string.

Any ideas?



>>> class A():
>>> a = A()
>>> a.__class__.__name__


you can also create a dict with the classes themselves as keys, not necessarily the classnames

    int:lambda x: x*2,
    str:lambda s:'(*(%s)*)'%s

def transform (param):
    print typefunc[type(param)](param)

transform (1)
>>> 2
transform ("hi")
>>> (*(hi)*)

here typefunc is a dict that maps a function for each type. transform gets that function and applies it to the parameter.

of course, it would be much better to use ‘real’ OOP
