String Indices Must Be Integers

The whole characters from a string own a different index. That index defines the state of every string's character. If you define a string or else float as the index, you will face an error which is called the String Indices Must be Integers.

All the characters of a string have a unique index . This index specifies the position of each character of the string. TypeError: string indices must be integers means an attempt to access a location within a string using an index that is not an integer. 

For example, str[hello"] and str[2.1] as indexes. As these are not integers, a TypeError exception is raised. This means that when you're accessing an iterable object like a string or float value, you must do it using an integer value .

Python supports slice notation for any sequential data type like lists, strings , tuples, bytes, bytearrays, and ranges. When working with strings and slice notation, it can happen that a TypeError: string indices must be integers is raised, pointing out that the indices must be integers, even if they obviously are.
