How Can I List All Functions, Classes, and Methods Within a Python Module?

How to Inspect a Module's Content in Python

When working with external Python modules, it's often necessary to explore their contents to understand the available functionality. This question explores how to list all functions, classes, and methods within a module, similar to Ruby's ClassName.methods.

To achieve this in Python, use the dir(module) function. It provides a list of all names defined within the specified module, including functions, classes, methods, and other attributes.

For instance, let's consider a hypothetical module named "somemodule":

from somemodule import foo

To list all functions accessible through foo, you could use this syntax:

dir(foo)

This would output a list of all available attributes and methods within the foo module.

Note that dir(module) does not provide information about the module's internal implementation details, such as private methods or protected variables. However, it offers a comprehensive view of the publicly accessible components within the module. Additionally, you can use the help() function to display the documentation for a specific function or attribute within a module.
