Return 0.0 and 1.0 if input falls below 0.0 or above 1.0

The goal is to "do something" if the input value falls between (0.0, 1.0).

Otherwise,

• return 1.0 if input is >= 1.0 or
• return 0.0 if input is <= 0.0

The straightforward way would be to:

def func(x):
    if x >= 1.0:
        return 1.0
    elif x <= 0.0:
        return 0.0
    else: 
        return do_something(x)

But it's also better to use some max/min trick like this:

def func(x):
    if 0 < x < 1.0:
        return do_something(x)
    else:
        return max(min(x, 1.0), 0.0)

Which coding style more Pythonic returning clipped values if it falls below 0 and above 1 and if otherwise, the float needs to be manipulated?

do_something() is some float manipulation that should return a value between (0.0, 1.0), i.e. exclusive of 0.0 and 1.0.

For simplicity, treat it as:

def do_something(x):
    return x**2
