The “TypeError: list indices must be integers or slices, not str” error is raised when we try to access a value of a list using anything but numbers or slices. This error is usually solved by calling the int() function…

If you want to convert a list of strings to a list of integers, you can use different techniques: Use the map() function Use a list comprehension to create a new list from your initial list Use the enumerate() function…

Lists are one of the most common data types you’ll be using if you start coding with Python. One of the usual checks you may have to perform is to check if a list is empty. In this tutorial, we’ll…

When you work with numerical list in Python, you may need to apply aggregation like finding the average. Most common operations are built-in in Python and no extra-code is needed. That being said, there is no function or method to…
