title: Python Abs Function
---
`abs()` is a built-in function in Python 3, to compute the absolute value of any number. The absolute value of a number "means only how far a number is from 0" <sup>1</sup> It takes one argument `x`. The argument can even be a <a href='https://docs.python.org/3.0/library/cmath.html' target='_blank' rel='nofollow'>complex number</a>, or a <a href='https://en.wikipedia.org/wiki/Expression_(mathematics)' target='_blank' rel='nofollow'>mathematical expression</a>.
