Examples

Basic Usage

Here is an example of how to use datetime.combine to combine a date and time into a datetime object.

Example

from datetime import datetime, date, time

# Creating a date object
date_obj = date(2024, 7, 20)

Combining Date and Time

This example shows how to combine the current date with a specific time.

# Defining a specific time
specific_time = time(9, 45)

# Combining the current date with the specific time
combined_datetime = datetime.combine(current_date, specific_time)
print("Combined datetime with current date:", combined_datetime)

Output:

Combined datetime with current date: 2024-07-23 09:45:00
