Python built-in Method - help()

The help() method in Python is a built-in function that provides interactive help and documentation for Python modules, classes, functions, and methods.

The syntax for help() is as follows:

help([object])

Here, object is an optional argument that can be used to get help and documentation for a specific Python object.

For example:

help(list)

In the example above, we use the help() function to get documentation and help for the built-in list class.

The help() function opens up an interactive help system in the console, where you can navigate through the documentation using arrow keys and view examples and usage information for the object.

You can also use help() to get help and documentation for specific methods or functions, such as:

s = "Hello, world!"
help(s.upper)

In the example above, we use the help() function to get help and documentation for the upper() method of the string s.

The help() function is a powerful tool for understanding and learning Python's built-in modules and functions, as well as third-party modules and libraries. It can also be used to quickly look up the syntax and usage of a particular method or function.
