如何将列表间隔(字符串格式)转换为整数？

def str_list_to_int_list(str_ranges):
    int_list = []
    for r in str_ranges:
        start, end = map(int, r.split('-'))
        int_list.extend(range(start, end + 1))
    return int_list

# 示例使用
str_ranges = ["1-5", "10-15", "20-25"]
int_list = str_list_to_int_list(str_ranges)
print(int_list)  # 输出: [1, 2, 3, 4, 5, 10, 11, 12, 13, 14, 15, 20, 21, 22, 23, 24, 25]

def str_list_to_int_list(str_ranges):
    int_list = []
    for r in str_ranges:
        try:
            start, end = map(int, r.split('-'))
            if start > end:
                raise ValueError("Start of range is greater than end.")
            int_list.extend(range(start, end + 1))
        except ValueError as e:
            print(f"Invalid range: {r}. Error: {e}")
    return int_list
