我的for循环不适用于遍历字符串列表

Question

我想遍历数据集以选择自己选择的变量

Asian_teams=['India','Pakistan','Sri Lanka','Bangladesh']
Top_western_sides=['England','South Africa','New Zealand','Australia']
other_teams=list(set(raw_data['Winner'].unique())-set(Top_western_sides)-set(Asian_teams))

Asian_count=0
western_count=0

for i in range (raw_data.shape[0]):
    for teams in Top_western_sides:
         if raw_data['Host_Country'][i] == teams:
            for asianteams in Asian_teams:
                if raw_data['Winner'][i] == asianteams:
                    Asian_count = Asian_count + 1

            for teams in Top_western_sides:
                if raw_data['Winner'][i] == teams:
                    western_count = western_count + 1

我希望诸如Asian_count和Western_count之类的计数器能够得出结果，但是错误指出“ 255L”是一个关键错误，它指向第9行（如果声明）
