Python -时间单位转换的最佳实践

from datetime import datetime

date_str = "2022-01-01 12:00:00"
date_obj = datetime.strptime(date_str, "%Y-%m-%d %H:%M:%S")

from datetime import datetime

date_obj = datetime.now()
date_str = date_obj.strftime("%Y-%m-%d %H:%M:%S")

from datetime import datetime, timedelta

start_date = datetime(2022, 1, 1)
end_date = datetime(2022, 1, 2)
time_delta = end_date - start_date

from datetime import timedelta

# 将时间间隔转换为秒
seconds = time_delta.total_seconds()

# 将时间间隔转换为分钟
minutes = time_delta.total_seconds() / 60

# 将时间间隔转换为小时
hours = time_delta.total_seconds() / 3600

# 将时间间隔转换为天数
days = time_delta.days
