String IndexError(index out of range) Exception

An IndexError is raised when you try to access a character at a position that doesn’t exist in a string.

This happens when the index is greater than the highest available position in the string.

For example, the string "hello" has 5 characters (index 0 to 4), so accessing s[5] or beyond will raise an IndexError.

String indices start from 0, so in the string "hello", s[4] is valid, but s[5] is not.

To prevent this error, ensure that you check the length of the string and only access indices that fall within the valid range.

Copy
word = "Python"
# Correct indexing
print(word[0])  # 'P'

# IndexError occurrence
print(word[6])  # IndexError: string index out of range
