The \`getargspec\` function in the \`inspect\` module enforces the input parameter to be either a method or a function.
The \`getargspec\` already works with classes, callable objects, and some builtins.
It's also deprecated, in part because its API can't handle various features (like keyword-only arguments). There is an extended version that can handle some of those features, but as of 3.5 that one is deprecated as well.
The \`signature\` function is much easier to use, as well as being more powerful.
def getargspec(func):"""Get the names and default values of a function's arguments.A tuple of four things is returned: (args, varargs, varkw, defaults).'args' is a list of the argument names (it may contain nested lists).'varargs' and 'varkw' are the names of the \* and \*\* arguments or None.'defaults' is an n-tuple of the default values of the last n arguments."""if ismethod(func):func = func.im\_funcif not isfunction(func):raise TypeError('{!r} is not a Python function'.format(func))args, varargs, varkw = getargs(func.func\_code)return ArgSpec(args, varargs, varkw, func.func\_defaults)Passing in a callable which is not a function causes a TypeError to be raised.I think in this case any callable should be allowed, allowing classes and callable objects as well.We can switch on whether \`func\` is a function, a class or a callable object, and pass into \`getargs\` the appropriate value.What is your opinion?Thank you
