from datetime import date def convert_to_integer(date_str): # 将日期字符串转换为date对象 dt = date.fromisoformat(date_str) # 获取日期的Gregorian日历序数 ordinal = dt.toordinal() # 返回整数值 return ordinal # 示例调用 date_str = '2022-01-01' integer_value = convert_to_integer(date_str)...
days_to_convert = timedelta(days=5) 使用timedelta对象对datetime对象进行加法运算,得到新的datetime对象。将结果赋值给一个变量,比如new_date: 代码语言:txt 复制 new_date = my_date + days_to_convert 最后,将新的datetime对象转换为整数,可以使用date().toordinal()方法: 代码语言:txt 复制 integer_days =...

The next common error occurs when you pass an integer to datetime.strptime() or time.strptime() instead of a string. Ensure all the values you’re passing to the function are strings. # Example 1: Integer instead of string date_int = 20230301 date_obj = datetime.datetime.strptime(date_in...
利用datetime模块来完成不同时间单位间的换算,timedelta实例完成时间间隔换算 #Python学习交流群:309488165 In [103]: from datetime import datetime,timedelta #当前时间加2天后的时间 In [104]: datetime.now() + timedelta(days=2) Out[104]: datetime.datetime(2018, 11, 17, 14, 0, 16, 257925) #当前...
