to_csv 仅保存最后一次出现（python）

Question

I have a df resulting from a loop (which is part of a longer program that's why I'm not posting it).

If I use print I get the whole df if I use write I get the whole df if I use to_csv I get only the last occurence (regardless the indentation)

Thank you for the help

Edit: code added

j = range(14)
selections = []
for ind in j:
    selections.append(files[ind])
    for selection in selections:
        first_classes = selection.find('ul', class_='first_class')
        second_classes= first_class.find_all('li', class_='second_class')
        list = []
    for second_class in second_classes:
        name = second_class.find('a').text
        list.append(name)
    i = range(5)
    h = []
    for index in i:
        h.append(list[index])
    df = pd.DataFrame(h)
    df.to_csv('myfile.csv', index=False, header=False)

您需要在它之前的循环中获取最后一个for循环。
