datetime module offers a suite of classes for working with dates and times, including
tzinfo. These classes provide a powerful and flexible way to store, manipulate, and format dates and times in Python.
date class represents a date (year, month, day) and offers methods to perform various date-related operations such as retrieving the current date, formatting dates for output, and performing date arithmetic.
time class represents the time of day and offers methods to perform operations such as formatting times for output and performing time arithmetic.
datetime class combines the features of the
time classes, providing methods to work with both dates and times in a single object.
timedelta class represents a duration or the difference between two dates or times, enabling you to perform arithmetic with dates and times by adding or subtracting
tzinfo class allows you to store time zone information and to perform time zone conversions.
Formatting Dates and Times for Output
strftime method of the
datetime classes lets you format dates and times for output. The method takes a format string as an argument and returns a string representation of the date or time in the specified format.
Parsing Dates and Times from Strings
strptime method of the
datetime classes allows you to parse dates and times from strings. The method takes a format string as an argument and returns a
Performing Date Arithmetic
You can perform arithmetic with dates and times by adding or subtracting
timedelta objects. This makes it easy to calculate future or past dates and times.
Time Zone Conversions
pytz library offers time zone support for Python, simplifying time zone conversions.
Here are some examples to help you get started with the
datetime module in Python.
Example 1: Formatting a Date and Time for Output
import datetime # Get the current date and time now = datetime.datetime.now() # Format the date and time for output output = now.strftime("%Y-%m-%d %H:%M:%S") print(output)
Example 2: Parsing a Date and Time from a String
import datetime # Define a date and time string date_string = "2022-01-01 12:00:00" # Parse the date and time string parsed_datetime = datetime.datetime.strptime(date_string, "%Y-%m-%d %H:%M:%S") print(parsed_datetime)
Example 3: Performing Date Arithmetic
import datetime # Get the current date and time now = datetime.datetime.now() # Calculate the date and time one week from now one_week_from_now = now + datetime.timedelta(weeks=1) print(one_week_from_now)
Example 4: Time Zone Conversions
import datetime import pytz # Define a time zone eastern = pytz.timezone("US/Eastern") # Get the current date and time in the Eastern time zone now_eastern = datetime.datetime.now(eastern) # Convert the date and time to the UTC time zone now_utc = now_eastern.astimezone(pytz.utc) print(now_eastern) print(now_utc)
Example 5: Formatting a Timestamp for Output
import datetime # Get the current timestamp timestamp = datetime.datetime.timestamp(datetime.datetime.now()) # Format the timestamp for output output = datetime.datetime.fromtimestamp(timestamp).strftime("%Y-%m-%d %H:%M:%S") print(output)
As you can see, the
datetime module in Python provides a range of powerful and flexible tools for working with dates and times. Whether you need to format dates and times for output, parse dates and times from strings, perform date arithmetic, or perform time zone conversions, the
datetime module has you covered. With the help of this guide, you'll be able to harness the full power of the
datetime module to perform a wide range of date and time-related tasks in Python.
