Comparing two lists and removing elements which don't meet the criterion in Python

I have two lists J_new and C. For every True element of C, I want to remove the corresponding element in J_new. For instance, since C[0]=True, I want to remove J_new[0]=1. I present the current and expected outputs.

J_new = [1, 9, 15]
C=[True, True, False]

for i in range(0,len(C)): 
    if(C[i]=='True'):
        C[i]=[]
        J_new=J_new[C[i]]
print(J_new)

The current output is

[1, 9, 15]

The expected output is

[15]

>Solution :

When accessing parallel lists, always think "zip"!

>>> J_new = [1, 9, 15]
>>> C = [True, True, False]
>>> 
>>> [j for j, c in zip(J_new, C) if not c]
[15]
