Usage of iptyhon

1. Command completion

When entering an expression in the shell, as long as you press the Tab key, any variables (objects, functions, etc.) in the current command control that match the entered string will be found.

2. Object introspection

Add a question mark (?) before or after a variable to display some general information about the object. This is called introspection of an object.

If the object is a function or instance method, its docstring will also be displayed.

Using ?? will also display the source code of the function.

Some strings are matched with wildcard characters (*) to display all names that match the wildcard expression.
