Python - 拆分函数 - 列表索引超出范围

Question

我正在尝试在 for 循环中获取子字符串。为此，我正在使用这个:

for peoject in subjects:
        peoject_name = peoject.content
        print(peoject_name, " : ", len(peoject_name), " : ",  len(peoject_name.split('-')[1]))

我有一些项目的句子中没有任何“-”。我该如何处理这个问题？

我遇到这个问题:

builtins.IndexError: list index out of range

Answer 1

for peoject in subjects:
    try:
        peoject_name = peoject.content
        print(peoject_name, " : ", len(peoject_name), " : ", len(peoject_name.split('-')[1]))
    except IndexError:
        print("this line doesn't have a -")
