从python变量中获取年、月和日

from datetime import datetime

# 假设你有一个日期字符串变量
date_str = "2023-04-05"

# 使用strptime方法将字符串解析为datetime对象
date_obj = datetime.strptime(date_str, "%Y-%m-%d")

# 获取年、月和日
year = date_obj.year
month = date_obj.month
day = date_obj.day

print(f"Year: {year}, Month: {month}, Day: {day}")

from datetime import datetime

# 假设你已经有一个datetime对象
date_obj = datetime(2023, 4, 5)

# 获取年、月和日
year = date_obj.year
month = date_obj.month
day = date_obj.day

print(f"Year: {year}, Month: {month}, Day: {day}")
