How can I retrieve a list of all methods defined in a Python class?

Obtaining Class Methods in Python

Python classes provide various methods for accessing their functionality. To obtain a list of all methods defined in a class, you can employ the inspect.getmembers() function.

Usage:

<code class="python">from inspect import getmembers

# Get class methods
class_methods = getmembers(class_object, predicate=inspect.ismethod)</code>
Copy after login

Parameters:

  • class_object: The class for which you want to retrieve methods.
  • predicate: A filter function that indicates which members to include. Only methods are included by default.

Return Value:

  • A list of tuples, where each tuple represents a class member. The first element is the member's name, and the second element is the member's value (usually an unbound method).

Example:

To list the methods defined in the optparse.OptionParser class, use the following code:

<code class="python">from optparse import OptionParser
import inspect

class_methods = inspect.getmembers(OptionParser, predicate=inspect.ismethod)

print(class_methods)</code>
Copy after login

Output:

[(('__init__', &lt;unbound method OptionParser.__init__&gt;),
  ('add_option', &lt;unbound method OptionParser.add_option&gt;),
  ...)]
Copy after login

Note:

  • getmembers() can also be used to retrieve attributes and other class members.
  • Passing an instance of a class to getmembers() instead of the class itself allows you to access the class's methods and attributes bound to the specific instance.
