Clamping floating numbers in Python?

Question

Is there a built-in function for this in Python 2.6?

Something like:

clamp(myValue, min, max)

Answer 1

There’s no such function, but

max(min(my_value, max_value), min_value)

will do the trick.

Answer 2

Numpy’s clip function will do this.

>>> import numpy
>>> numpy.clip(10,0,3)
3
>>> numpy.clip(-4,0,3)
0
>>> numpy.clip(2,0,3)

I think the question is answered but here’s an alternative DIY solution if anyone needs it:

def clip(value, lower, upper):
    return lower if value < lower else upper if value > upper else value

(Slightly faster than @Sven Marnach’s answer – even when in bounds).
