Dealing with Dates and Times in Python

1. Working with Dates

What Day is it Today?Creating a Date Object Date Attributes Date Methods Date Formats One More Formatting Date Difference Arithmetic Operations with timedelta Objects

2. Working with Times

What Time is it Now?Creating a datetime Object Datetime Attributes Datetime Methods Datetime Formats 12-Hour and 24-Hour Formats Date and Time Difference Reading Date and Time from String

3. Timezones and Daylight Savings Time (DST)

The Variery of Timezones Timezone Examples Applying Timezone to Datetime Object What Time is it in ... ?Daylight Savings Time

4. Working with Dates and Times in pandas

Challenge: What Will We Work With?Challenge: Converting Columns into datetime Type Challenge: Extreme Trips Durations Challenge: Investigation Challenge: Negative Trip Duration Challenge: Is this Common Issue?Challenge: Fixing the Issues Challenge: Average Metrics Across Taxi Types Challenge: Corrected Metrics Across Taxi Types Challenge: Group by Period?

Date and Time Difference

Remember the timedelta object we learned in the first section? At that time we missed the time part in timedelta objects since we compared two dates only. Now there is even more sense in using timedelta since we can perform different operations with time also.

For example, imagine that we have both departure and arrival times on the ticket. Using timedelta we can easily calculate the expected duration for this trip.

Departure: 25 May 2021, 18:20
Arrive: 26 May 2021, 07:40


              12345678910
            
# Load classes from library
from datetime import datetime
from datetime import timedelta

# Create two datetimes objects
dep = datetime(2021, 5, 25, 18, 20)
arr = datetime(2021, 5, 26, 7, 40)

# Calculate estimated trip duration
print(f"Estimated trip duration: {arr - dep}")

Завдання

Sydney - Perth is one of the world's longest direct rail route, running for 4,352 kilometers or 2,704 miles. The ticket information looks as follows:

Departure: July 19, 03:00 PM
Arrival: July 23, 03:00 PM.

The year on the tickets is 2022. Create variables dep and arr with the respective dates and times and calculate the duration of such a trip.
