How to import a module in Python?

To import a module in Python, you can use the import keyword followed by the name of the module.

Here are the different ways to import a module:

1. Import the entire module:

   import <module_name>

   Example:

   import math

   This will import the math module, allowing you to use its functions and variables.

2. Import a specific function/variable from a module:

   from <module_name> import <function/variable_name>

   Example:

   from math import sqrt

   This will import only the sqrt function from the math module, allowing you to use it directly without referencing the module name.

3. Use an alias for the module:

   import <module_name> as <alias_name>

   Example:

   import math as m

   This will import the math module and use m as an alias for it. You can then use functions and variables using the alias, e.g., m.sqrt().

Once you have imported a module, you can use its functions, variables, or classes in your code. For example:

Note: Make sure the module you want to import is installed on your system. If not, you can install it using package managers like pip.
