List Index Out of Range Occur in Python when an item from a list is tried to be accessed that is outside the range of the list. Before we proceed to fix the error, let’s discuss how indexing work in Python. What Causes an IndexError in Python
Example: Here our list is 3 and we are printing with size 4 so in this case, it will create a list index out of range. Python3
IndexError: string index out of range0 IndexError: string index out of range1 IndexError: string index out of range2 IndexError: string index out of range1 IndexError: string index out of range4 IndexError: string index out of range5 IndexError: string index out of range6 IndexError: string index out of range7 IndexError: string index out of range4 IndexError: string index out of range9 Output IndexError: list index out of rangeSimilarly, we can also get an Indexerror when using negative indices. Python3blue,red,green 0`=` blue,red,green 2 IndexError: string index out of range6 blue,red,green 4 blue,red,green 5 blue,red,green 6 IndexError: string index out of range9 Output IndexError: string index out of rangeHow to Fix IndexError in Python
How to Fix List Index Out of Range in PythonLet’s see some examples that showed how we may solve the error.
Python Fix List Index Out of Range using Range()The range is used to give a specific range, and the Python range() function returns the sequence of the given number between the given range.
