Examples of Importing in Python

1. Importing an Entire Module

In this example, we import the entire math module and then use the sqrt() function from that module to calculate the square root of 16.

2. Importing Specific Functions from a Module

Here, we import only the sqrt function from the math module. This way, we can call sqrt() directly without needing to prefix it with math..

3. Importing a Module with an Alias

This example shows how to import a module with a shorter alias (np for numpy). It makes it easier to use the functions and classes of the package without typing the full name every time.

4. Importing All Functions from a Module

By using the *, we import all functions and variables from the math module into our program's namespace. However, this can be risky because it can cause name conflicts if there are other functions or variables with the same name.
