Python Count the number of substring in list from other string list without duplicates

Question

I have two list:

main_list = [\'Smith\', \'Smith\', \'Roger\', \'Roger-Smith\', \'42\']
master_list = [\'Smith\', \'Roger\']

I want to coun

Answer 1

This would do it:

main_list = ['Smith', 'Smith', 'Roger', 'Roger-Smith', '42']
master_list = ['Smith', 'Roger']

i = 0
for elem in main_list:
    if elem in master_list:
        i += 1
        continue
    for master_elem in master_list:
        if master_elem in elem:
            i += 1
            break

print(i) # i = 4

The code above counts 'Roger-Smith' as 1, if you want it to count as multiple, remove the break.
