Removing elements from a list based on indices in another list in Python

I have a list J. I want to remove specific elements from J[0] based on index. For example, I want to remove J[0],J[3] based on elements in index. But I am getting an error. I present the expected output.

J=[[2, 6, 9, 10]]

index=[[0,3]]

for i in range(0,len(J)):
    for k in range(0,len(index)): 
        J[i].remove(index[k][0])
print(J)

The error is

 in <module>
    J[i].remove(index[k][0])

ValueError: list.remove(x): x not in list

The expected output is

[6,9]

>Solution :

Try list comprehension / filtering (and fix the [0] as required):

new_J = [j for i,j in enumerate(J[0]) if i not in index[0]]
