How Can I Retrieve Parameter Names within a Python Function Without inspect?

Retrieving Parameter Names within a Python Function

In Python, it is possible to introspect a function to obtain various details, including its parameter names. This information can be useful for documentation, debugging, and other purposes.

One method to retrieve parameter names is by using the inspect module. However, an alternative approach exists that eliminates the dependency on external modules.

Inspect-Less Method

Within a function, the __code__ and __defaults__ attributes of the function object can be utilized to extract the parameter names. Here's an example:

<code class="python">def func(x, y):
    print(func.__code__.co_varnames)  # ('x', 'y')</code>
Copy after login

The co_varnames attribute returns a tuple containing the names of the positional parameters. If a function has default values for certain parameters, these can be accessed through the __defaults__ attribute.

Conclusion

By leveraging the __code__ and __defaults__ attributes, we can conveniently obtain the list of parameter names within a Python function without relying on additional modules like inspect.
