In Python, a string is a single-dimensional array of characters. The string index out of range means that the index you are trying to access does not exist. In a string, that means you're trying to get a character from the string at a given point. If that given point does not exist , then you will be trying to get a character that is not inside of the string. Indexes in Python programming start at 0. This means that the maximum index for any string will always be length-1. There are several ways to account for this. Knowing the length of your string (using len() function)could certainly help you to avoid going over the index.
