Rounding up to nearest 30 minutes in Python

Rounding up to nearest 30 minutes in Python

To round up a given time to the nearest 30 minutes in Python, you can use the datetime module to perform the calculations and adjustments. Here's how you can do it:

from datetime import datetime, timedelta def round_up_to_nearest_30_minutes(dt): remainder = dt.minute % 30 if remainder == 0: return dt else: return dt + timedelta(minutes=30 - remainder) # Current time current_time = datetime.now() # Round up to nearest 30 minutes rounded_time = round_up_to_nearest_30_minutes(current_time) print("Current Time:", current_time) print("Rounded Time:", rounded_time)

In this example, the round_up_to_nearest_30_minutes() function takes a datetime object as input, calculates the remainder when minutes are divided by 30, and adjusts the time accordingly. If the remainder is 0, the function returns the input time. Otherwise, it adds the appropriate number of minutes to round up to the nearest 30 minutes.

You can replace current_time with any other datetime object that you want to round up. The resulting rounded_time will be adjusted to the nearest 30-minute interval.
