Python TypeError list indices must be integers not str

Title: Understanding and Resolving Python TypeError: "list indices must be integers, not str"
Introduction:
When working with Python, you might encounter the TypeError: "list indices must be integers, not str." This error occurs when you attempt to use a string as an index to access elements in a list, which is not allowed. This tutorial will help you understand the error and provide solutions to resolve it.
Understanding the Error:
Let's break down the error message:
This message indicates that you are trying to use a string (str) as an index to access elements in a list, but list indices must be integers. Python does not allow using non-integer values as indices for lists.
Common Causes:
Using Strings as List Indices:
Accidentally Using a String Variable:
Now, let's explore how to resolve this issue.
Ensure that you are using integers as indices when accessing elements in a list.
If you have a string representing an index, convert it to an integer before using it.
Check the types of variables you are using as indices. Ensure they are integers.
By following these solutions, you can address the "list indices must be integers, not str" TypeError in your Python code. Always be mindful of the data types you are using, especially when working with indices in lists.
