# When You Need a Sequence, You Need a Sequence

## It’s so easy to get this wrong!

Commas make sequences and sequences are *a single*
thing

- For example,

the function `min()` returns the
minimum value *in a sequence*
`min((8, 5, 23))` returns `5`
`min(5)` returns `5`
- But
`min(8, 5, 23)` would return an
error

`min()` needs a sequence, and we're giving it three numbers
