# Quick Python: Length of Iterables

I wanted to find the length of what I know is a finite iterable. Normally you would think of using the `len`

function but it does not work in this case. Al Hoo on StackOverflow shared a quick snippet to calculate this.

```
from functools import reduce
def ilen(iterable):
return reduce(lambda sum, element: sum + 1, iterable, 0)
```

This also turns out to be memory efficient since we are only loading in one object into memory from the iterable at a time.
