I saw it used in the exercises but I didnt really understand.. It would also help if I had an example or a practical

Answer 1

Those functions return certain data types, which you may want to carry out operations on.

For example, you ask for user input, let's say his age. The input() method returns a string, which is the most capable data type, it can store any character. However, since you want to deal with a number, not a string, you have to convert it to int or float. Then you can use those functions.

It can be the other way round, too. For example, if you have a number and want to sort its digits in an order, you can convert it to string, use its sorted() method and convert the result back to integer.
