Date Object

• Date: not a data type of its own, but can import the datetime module to work with dates as date objects.

• Userful Property and Methods

import datetime

print("\n--------datetime.datetime--------\n")

xtime = datetime.datetime.now()

print("now():\t\t", xtime)                      # now():           2023-03-29 23:30:25.248756
print("type():\t\t", type(xtime))               # type():          <class 'datetime.datetime'>

print("\n--------Property--------\n")

print("year:\t\t", xtime.year)                  # year:            2023
print("month:\t\t", xtime.month)                # month:           3
print("day:\t\t", xtime.day)                    # day:             29
print("hour:\t\t", xtime.hour)                  # hour:            23
print("minute:\t\t", xtime.minute)              # minute:          30
print("second:\t\t", xtime.second)              # second:          25
print("microsecond():\t", xtime.microsecond)    # microsecond():   248756

print("max():\t\t", xtime.max)                  # max():           9999-12-31 23:59:59.99999
print("min():\t\t", xtime.min)                  # min():           0001-01-01 00:00:00

print("\n--------Method--------\n")

print("date():\t\t", xtime.date())              # date():          2023-03-2
print("time():\t\t", xtime.time())              # time():          23:30:25.248756
print("weekday():\t", xtime.weekday())          # weekday():       2
