Best way to write "nested if" for different ranges

I am going to write down this pseudocode in python:

if (i < .1):
   doX()
elif (i < .3):
   doY()
elif (i < .5):
    doZ()
.
.
else:
    doW()

The range of numbers may be 20, and each float number which shapes the constraints is read from a list. For the above example (shorter version), it is the list:

[0.1, 0.3, 0.5, 1]

Is there any pythonic way or a function which can do different functions for different associated ranges?
