What is the difference between Python imports and requirements?

What is the difference between Python imports and requirements?

Python imports are used to include modules in your code, while requirements specify external packages needed for your project.

Can you give me an example of how to use imports?

Sure! You can use import math to include the math module, allowing you to use functions like math.sqrt().

And how do I create a requirements.txt file?

You can create a requirements.txt file by listing the packages you need, one per line, like numpy or requests.

Is it necessary to have a requirements file for every project?

It's not mandatory, but it's a good practice for managing dependencies, especially in larger projects.
