Re: [Python-ideas] Consider adding clip or clamp function to math

When I really need such function, I define it like this:

def clamp(min_val, value, max_val): return min(max(min_val, value), max_val)

and your colleague next door defines it like this:

def clamp(min_val, value, max_val): return min(max_val, max(value , min_val))

and a third party library ships

def clamp(min_val, value, max_val): return max(min(max_val, value), min_val)

and combinatorially, there is at least a half-dozen more variations. The behavior of each variant is subtly different from the others. Having this function in stdlib would allow standardizing on one well-documented (and hopefully well-motivated) variant.
