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>
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>
Output:
[(('__init__', <unbound method OptionParser.__init__>), ('add_option', <unbound method OptionParser.add_option>), ...)]
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.
