The
<tt class=
"function">bisect()
</tt> function is generally useful for categorizing
numeric data. This example uses
<tt class=
"function">bisect()
</tt> 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.
<div class=
"verbatim"><pre>
>>> grades =
"FEDCBA"
>>> breakpoints = [
30,
44,
66,
75,
85]
>>> from bisect import bisect
>>> def grade(total):
... return grades[bisect(breakpoints, total)]
>>> map(grade, [
33,
99,
