Python Function Parameters: How to View Them

In Python, you can use the inspect module to view a function’s parameters. Here is an example code:

import inspect

def my_func(a, b, c=1, *args, **kwargs):
    pass

argspec = inspect.getfullargspec(my_func)
print("Positional arguments:", argspec.args)
print("Keyword-only arguments:", argspec.kwonlyargs)
print("Default values:", argspec.defaults)
print("Variable positional arguments (*args):", argspec.varargs)
print("Variable keyword arguments (**kwargs):", argspec.varkw)

In this example, the getfullargspec function will return a FullArgSpec object that contains the parameter information of the function my_func. You can access the properties of this object to see the parameter types, default values, variable parameters, and other information of the function.
