使用三种不同的日期类型库检查日期

from datetime import datetime

# 定义一个日期字符串
date_str = "2023-10-01"

# 将字符串转换为datetime对象
date_obj = datetime.strptime(date_str, "%Y-%m-%d")

# 检查日期是否在特定范围内
start_date = datetime(2023, 1, 1)
end_date = datetime(2023, 12, 31)

if start_date <= date_obj <= end_date:
    print(f"{date_str} is within the range.")
else:
    print(f"{date_str} is not within the range.")

pip install python-dateutil

from dateutil import parser
from datetime import datetime

# 定义一个日期字符串
date_str = "2023-10-01"

# 将字符串解析为datetime对象
date_obj = parser.parse(date_str)

# 检查日期是否在特定范围内
start_date = datetime(2023, 1, 1)
end_date = datetime(2023, 12, 31)

if start_date <= date_obj <= end_date:
    print(f"{date_str} is within the range.")
else:
    print(f"{date_str} is not within the range.")

pip install arrow

import arrow

# 定义一个日期字符串
date_str = "2023-10-01"

# 将字符串解析为arrow对象
date_obj = arrow.get(date_str, "YYYY-MM-DD")

# 检查日期是否在特定范围内
start_date = arrow.get("2023-01-01", "YYYY-MM-DD")
end_date = arrow.get("2023-12-31", "YYYY-MM-DD")

if start_date <= date_obj <= end_date:
    print(f"{date_str} is within the range.")
else:
    print(f"{date_str} is not within the range.")
