Question

I am comparing two arrays in Python.

The 1st array is a list of words from a query string. The second array is the list of words to be excluded from the query.

I have to compare these arrays and exclude words from the first array which are contained in the second array.

I tried to solve this by comparing each word from the first array to the whole of second array and continuing until all the words from the first array are exhausted:

for i in q_str:
    if  q_str[i] in stop_arr:
        continue
    else:
        sans_arr[j] = q_arr[i]
        j = j + 1

Where q_str is the query array, stop_arr contains the words to be excluded, and
sans_arr is a new array with the words excluded.

This code generates an error:

list indices must be integers not str

Answer 1

This code generates new array with all elements of q_str that not exists in stop_arr:

sans_arr = [ x for x in q_str if x not in stop_arr ]

Disclaimer: I don’t know if q_str is an array of string because you talk about a query array.
