Python Datetime Tutorial
Python has a special date class, called “date.” A date, like a string, or a number, or a numpy array, has special rules for creating it and methods for working with it.
Example of creating a datetime object
Here’s how to create a datetime object that computes the local time.
# Import datetime from the datetime module from datetime import datetime # Compute the local datetime: local_dt local_dt = datetime.now() # Print the local datetime print(local_dt)
Creating date objects
# Import date from datetime import date # Create Dates two_hurricanes_dates = [date(2016, 10, 7), date(2017, 6, 21)]
Here we’ve created dates corresponding to two hurricanes, now as python date objects. The inputs to date(), are the year, month, and day. The first date is October 7, 2016 and the second date is June 21, 2017.
Attributes of a Date
You can access individual components of a date using the date’s attributes. You can access the year of the date using the year attribute, like so, and the result is 2016. Similarly, you can access the month and day using the month and day attributes.
# Import date from datetime import date # Create Dates two_hurricanes_dates = [date(2016, 10, 7), date(2017, 6, 21)] print(two_hurricanes_dates.year) print(two_hurricanes_dates.month) print(two_hurricanes_dates.day)
