How Can I List All Functions Within a Python Module?

Retrieving Functions in a Python Module

When working with a Python module, it can be helpful to inspect the available functions, classes, and methods within it. This allows you to explore its capabilities and determine which components are accessible to your program.

To achieve this, you can utilize the built-in dir() function. dir(module) returns a list of all attributes available in the specified module. These attributes include functions, classes, and method names.

Example:

Suppose you have a module named "somemodule" installed on your system. To display a list of its functions and other attributes, you can use the following code:

import somemodule

# Get the list of attributes in the module
attributes = dir(somemodule)

# Print the function names
print("Functions:")
for item in attributes:
    if isinstance(getattr(somemodule, item), function):
        print("-", item)

By iterating through the list of attributes and checking their types, you can filter out and display only the function names.
