To get absolute value of a number in python, there is the "built-in" function abs(), example:

`>>> x = - 3`

`>>> abs(x)`

`3`

with a float:

`>>> x = - 6.0`

`>>> abs(x)`

`6.0`

Note: with a complex number, the function abs() gives the modulus

`>>> z = complex(3,4)`

`>>> abs(z)`

`5.0`

since

$\sqrt{3^2+4^2} = \sqrt{9+16} = 5$
