## 5.5.1 Examples

The `bisect()` function is generally useful for categorizing numeric data. This example uses `bisect()` to look up a letter grade for an exam total (say) based on a set of ordered numeric breakpoints: 85 and up is an `A', 75..84 is a `B', etc.

    >>> grades = "FEDCBA"
    >>> breakpoints = [30, 44, 66, 75, 85]
    >>> from bisect import bisect
    >>> def grade(total):
    ...           return grades[bisect(breakpoints, total)]
    ...
    >>> grade(66)
    'C'
    >>> map(grade, [33, 99, 77, 44, 12, 88])
    ['E', 'A', 'B', 'D', 'F', 'A']
