Table of Contents:

1. Introduction to Python DateTime:

   • Importance of DateTime in programming.
   • Overview of the DateTime module in Python.

2. Creating DateTime Objects:

   • Methods for creating DateTime objects.
   • Utilizing constructors and parsing strings to obtain DateTime instances.

from datetime import datetime

# Current date and time
current_datetime = datetime.now()

# Creating DateTime from a string
custom_datetime = datetime.strptime('2022-01-01', '%Y-%m-%d')

Accessing DateTime Components:

• Extracting date, time, and other components from DateTime objects.
• Understanding attributes like year, month, day, hour, minute, second, etc.

year = current_datetime.year
month = current_datetime.month
day = current_datetime.day
hour = current_datetime.hour
minute = current_datetime.minute
second = current_datetime.second

Performing Arithmetic with TimeDelta:

• Introduction to TimeDelta for representing time differences.
• Performing arithmetic operations to add or subtract time intervals.

from datetime import timedelta

# Time difference of 1 day
one_day_difference = timedelta(days=1)

# Calculating future date
future_date = current_datetime + one_day_difference

Formatting DateTime Strings with Strftime:

• Using the Strftime method to format DateTime objects as strings.
• Creating custom date and time representations.

formatted_date = current_datetime.strftime('%Y-%m-%d')
formatted_time = current_datetime.strftime('%H:%M:%S')

Parsing Strings to DateTime Objects with Strptime:

• Employing Strptime to convert formatted strings to DateTime objects.
• Handling different date and time formats.

custom_datetime = datetime.strptime('2022-01-01', '%Y-%m-%d')

Time Zone Awareness in DateTime:

• Understanding time zones and their significance.
• Working with time zone-aware DateTime objects.

from datetime import timezone

# Creating a time zone-aware DateTime
aware_datetime = datetime(2022, 1, 1, tzinfo=timezone.utc)

1. Handling Time and Date in Real-World Scenarios:

   • Practical examples of using DateTime in applications.
   • Dealing with scenarios like calculating age, scheduling tasks, etc.
