How to select strings contained in another library from a library?

Question

Python

There are two libraries stroka contains links, the second library gorod contains the city. the task is to select lines that do not contain a city.

wrote this code:

for line_stroka in stroka:
    if gorod1 in line_stroka:
        continue
    elif gorod2 in line_stroka:
        continue
    elif gorod3 in line_stroka:
        continue
    elif gorod4 in line_stroka:
        continue
    elif gorod5 in line_stroka:
        continue
    elif gorod6 in line_stroka:
        continue
    elif gorod7 in line_stroka:
        continue
    elif gorod8 in line_stroka:
        continue
    elif gorod9 in line_stroka:
        continue
    elif gorod10 in line_stroka:
        continue
    elif gorod11 in line_stroka:
        continue
    elif gorod12 in line_stroka:
        continue
    elif gorod13 in line_stroka:
        continue
    elif gorod14 in line_stroka:
        continue
    elif gorod15 in line_stroka:
        continue
    elif gorod16 in line_stroka:
        continue
    elif gorod17 in line_stroka:
        continue
    elif gorod18 in line_stroka:
        continue
    elif gorod19 in line_stroka:
        continue
    elif gorod20 in line_stroka:
        continue
    elif gorod21 in line_stroka:
        continue
    elif gorod22 in line_stroka:
        continue
    elif gorod23 in line_stroka:
        continue
    else:
        stroka_beth_gorod.append(line_stroka)

how can it be reduced to two cycles?
