Working with dates and times is a common requirement, especially for data analysis or scheduling tasks. The datetime module provides classes and functions to work with dates, times, and intervals.

import datetime

# datetime, date, time, timedelta, timezone

Examples:

from datetime import datetime, timedelta

# Current date and time
current_time = datetime.now()
print("Current date and time:", current_time)

# Custom date and time
custom_date = datetime(2022, 12, 31, 23, 59, 59)
print("Custom date and time:", custom_date)

# Convert string to datetime
date_str = "2023-01-01 00:00:00"
date_obj = datetime.strptime(date_str, "%Y-%m-%d %H:%M:%S")
print("String to datetime:", date_obj)

# Convert datetime to string
date_str2 = date_obj.strftime("%Y-%m-%d %H:%M:%S")
print("Datetime to string:", date_str2)

# Date and time arithmetic
one_day = timedelta(days=1)
yesterday = current_time - one_day
tomorrow = current_time + one_day
print("Yesterday:", yesterday)
print("Tomorrow:", tomorrow)
