Change the numbers of a list to another number python

Question

I have a list which has a range of numbers from 0 to 1:

[0.01,0.1,0.4,0.034,0.6,0.7,0.9,1]

How would I be able to edit the list so all the numbers from 0-0.5 to 0.4 and change all the numbers from 0.6-1 to 0.7, so the list becomes:

[0.4,0.40.40.4,0.7,0.7,0.7,0.7]

confindencenumbers = [(x=0.4) for x in confindencenumbers if x < 0.4]
confindencenumbers = [(x=0.7} for x in confindencenumbers if x > 0.5]

Really, there has to be some restriction you are not telling us, else it would be too trivial. — Cthulhu, May 05 '13 at 09:19
I've [already told you](http://stackoverflow.com/questions/16163394/turning-a-list-into-a-tuple-python#comment23098912_16163394) to research, or try something yourself, before you ask. This is a very simple problem. — Volatility, May 05 '13 at 09:21
That's [not a valid list comprehension](http://carlgroner.me/Python/2011/11/09/An-Introduction-to-List-Comprehensions-in-Python.html) — Volatility, May 05 '13 at 09:27

Downvoted. Lack of research in this as well as past questions of the OP. — DhruvPathak, May 05 '13 at 09:33

>>> l = [0.01, 0.1, 0.4, 0.034, 0.6, 0.7, 0.9, 1]
>>> [0.4 if (0. < f < 0.5) else 0.7 for f in l]
[0.4, 0.4, 0.4, 0.4, 0.7, 0.7, 0.7, 0.7]

[0.4 if 0 <= x <= 0.5 else 0.7 if 0.6 <= x <= 1 else DEFAULT_VAL for x in L]
