# 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.

<br />

## IndexError Example

```python title="Example of IndexError"
word = "Python"
# Correct indexing
print(word[0])  # 'P'

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

String indexing begins at 0, so accessing an index that exceeds the string's length causes an IndexError exception. For example, accessing 's[5]' in the string 'hello' which has a length of 5 is invalid.

### An `IndexError` occurs if you try to access an index beyond the length of the string.

String IndexError(index out of range) Exception

IndexError Example

An IndexError occurs if you try to access an index beyond the length of the string.

An `IndexError` occurs if you try to access an index beyond the length of the string.
