datetime.timedelta(days=0, seconds=0, microseconds=0, milliseconds=0, minutes=0, hours=0, weeks=0) 1. 所有参数都是可选的,参数可以为整数或浮点数,可以为正数或负数。在timedelta内部只保存days(天)、seconds(秒)和 microseconds(微秒)变量,所以其他参数milliseconds(毫秒)、minutes(分钟)和weeks(周)都应...
daysInMonth 方法返回了指定月份的天数,daysInYear 方法返回了指定年份的天数。 from PyQt6.QtCore import QDate, Qt now = QDate.currentDate() y = now.year() m = now.month() d = now.day() print(f'今天是 {now.toString(Qt.DateFormat.ISODate)}') xmas1 = QDate(y-1, 12, 25) xmas2...
