使用strptime()将数据转换为datetime对象会产生各种错误

from datetime import datetime

date_string = "2023-04-30"
format = "%Y-%m-%d"
datetime_obj = datetime.strptime(date_string, format)
print(datetime_obj)  # 输出: 2023-04-30 00:00:00

date_string = "2023-04-30T15:30:00+08:00"
format = "%Y-%m-%dT%H:%M:%S%z"
datetime_obj = datetime.strptime(date_string, format)
print(datetime_obj)  # 输出: 2023-04-30 15:30:00+08:00

from datetime import datetime

def parse_date(date_string, format):
    try:
        return datetime.strptime(date_string, format)
    except ValueError as e:
        print(f"Error parsing date: {e}")
        return None

# 正确的示例
date_str = "2023-04-30"
fmt = "%Y-%m-%d"
print(parse_date(date_str, fmt))  # 输出: 2023-04-30 00:00:00

# 错误的示例
date_str = "30-04-2023"  # 日期和月份颠倒了
print(parse_date(date_str, fmt))  # 输出错误信息
