A Beginner’s Guide to Using Imports in Programming: How to Add Pre-Existing Code and Functionality to Your Program with Ease

Imports

bring (goods or services) into a country from abroad for sale.

Imports in programming refer to the process of importing or bringing external libraries or modules into your program. These libraries can include pre-existing code that you can use to add functionality to your program.

In Python, for example, you can use the `import` statement to import a library. For instance, if you want to use the `math` library, you can use the following code:

“`
import math
“`

Once you import the library, you can use the functions and features provided by that library in your program. In this case, you can use math functions such as `sqrt()` or `pi` in your code.

You can also import specific functions or variables from a library using the `from` keyword. For example,

“`
from math import sqrt, pi
“`

This code will only import the `sqrt()` and `pi` functions from the math library, allowing you to use them without having to specify the library name every time.

Overall, using imports in programming can save time and effort by allowing you to utilize pre-existing code and features in your program.
