Difference between dir() and help()

Both dir() and help() are built-in functions in Python that provide information about objects, but they serve slightly different purposes.

dir() Function in Python

The dir() function returns a list of valid attributes and methods of an object. It provides a way to introspect an object and see what attributes and methods are available for use. It's useful for exploring the capabilities of an object.

my_list = [1, 2, 3] attributes_and_methods = dir(my_list) print(attributes_and_methods)

The dir() function returns a list containing various attributes and methods that can be used with the my_list object, including built-in methods like append, clear, count, etc.

help() Function in Python

The help() function provides interactive help for objects, functions, modules, etc. It displays information about an object, including its docstring (if available) and its methods and attributes. It's particularly helpful for understanding how to use an object or function properly.

my_string = "Hello, world!" help(my_string)

When you run help(my_string), you'll see detailed information about the str (string) object, including its methods, attributes, and a description of how to use them.

dir() VS. help() in Python

  1. dir() provides a list of attributes and methods available for an object.
  2. help() provides more detailed and interactive documentation about an object, including its docstring and usage instructions.

Remember, both functions can greatly aid in understanding and working with Python objects, making them valuable tools for learning and development.

Conclusion

Python dir() is used to list the attributes and methods of an object, providing an overview of its capabilities, while help() offers more detailed interactive documentation about an object, including its methods, attributes, and usage instructions, aiding in understanding its functionality.
