TypeError: 'DataFrame' object is not callable

Таких функций несколько. Хочу поместить их в цикл for, чтобы пройтись по списку страниц сайта.

Пока для теста это выглядит так:

if __name__ == '__main__':   
    u = 1
    driver.get(MyLinks.iloc[u,0])
    Table1 = Table1(u)
    #Table2 = Table2(u)
    #Table3 = Table3(u)
    #Table4 = Table4(u)

Проблема в том, что когда выделяю просто строку, например Table1 = Table1(u) и нажимаю F9, все прекрасно работает. Но когда выделяю весь код, выдает ошибку TypeError: 'DataFrame' object is not callable .

Пробовала использовать return(FirstTable) вместо return FirstTable все равно не работает.

The error traceback

Выдает следующее:

Traceback (most recent call last):

  File "<ipython-input-10-844b48fac0c3>", line 5, in <module>
    Table2 = Table2(u)
