How to Store Date and Time in PythonUsing the datetime Python library to store date and time efficientlyPhoto by Waldemar Brandt on UnsplashThe datetime library allows us to store easily dates and times in our programs. It provides three main classes:
In the following sections, we will see how to use these three classes. Creating a new variableClass ConstructorsEach class has its own constructor. For the d = date(year, month, day) Each value should be an integer, and the year can be any number between 1 and 9999. For the t = time(hour, minute, second, microsecond) Each variable must be in the following range:
Finally, the constructor for dt = datetime(year, month, day, hour, minute, second, microsecond) Create from a String
dt = datetime.strptime(date_string, format) The dt = datetime.strptime("12:30 15/06/2021", "%H:%M %d/%m/%Y") There are many symbols that can be used to specify the format of the string. The most important are:

Modifying an objectIt is possible to modify a single field of an object by using the d = date(2021, 7, 20) Getting values from objectsThe values of the day, month, year (for dt = datetime(2021, 7, 21, 14, 30, 0, 0) Get the data as a StringWe can also get the value stored in a dt = datetime(2021, 7, 21, 14, 30, 0, 0) To check which symbols can be used in the format string, see here. Get the day of the weekThe function d = date(2021, 7, 28) Arithmetic operationsWith the Datetime library, it is also possible to perform arithmetic operations over dates
and times. In order to do so there is another class, timedelta(days=0, seconds=0, microseconds=0, milliseconds=0, minutes=0, hours=0, weeks=0) To get the total time stored in a elapsed = timedelta(hours = 1) This class can be used to increase or reduce the value stored in a We can:
Other useful methodsThere are many other methods that can be useful when dealing with dates. First of all, there is a built-in method to get the current date and time:
Converting objectsWe can also convert a dt = datetime(2021, 7, 21, 14, 30, 0, 0) ConclusionThank you for reading through to the end!
