Take array of indices, find matching indices in another array and replace values

Question

I have two arrays, one array that contains all indices of two arrays that meet a certain condition I had made previous to this. The other array is an array of booleans. I want to take the array of indices and find the same place in the array of booleans and replace those values.

So for example what I am looking to do is:

myIdxs = [0, 3, 5]
myBools = [1, 0, 0, 1, 1, 1, 0, 1, 0, 1] 

and change myBools to:

myBools = [0, 0, 0, 0, 1, 0, 0, 1, 0, 1]

I've tried:

myBools = [myBools[i] for i in myIdx == 0]

But this does not give me the desired output.

Answer 1

I hope this works (not sure what you need):

myIdxs = [0, 3, 5]
myBools = [1, 1, 1, 1, 1, 0]

myBools = [myBools[i] if i in myIdxs else 0
        for i in xrange(len(myBools))]

>>> print myBools
[1, 0, 0, 1, 0, 0]
