Splitting Time Ranges into Periods with Python

Managing time efficiently is crucial in many applications, from scheduling meetings to tracking project hours. Today, we’re going to tackle a common problem: how to split a time range into multiple periods based on an interval using Python. Specifically, we'll demonstrate how to break a period like 9:30 to 11:30 into half-hour slots.

The Problem

Imagine you need to break a set period into manageable chunks. For example, if you have a time range from 9:30 to 11:30 and you want to split this into 30-minute intervals, how can you achieve this using Python? The desired output should be a list of datetime objects that clearly show the start and end times of each period.

Example Input

Start Time: 9:30 AM

End Time: 11:30 AM

Interval: 30 minutes

Expected Output

You want to obtain the following list of datetime ranges:

The Solution

To solve this problem, we can utilize Python's built-in datetime module, which provides powerful functionality for working with date and time. Below is a step-by-step explanation of how to split the time range.

Step 1: Import Necessary Libraries

First, we need to import the datetime module and the timedelta class, allowing us to perform arithmetic operations on datetime objects.

Step 2: Define Start, End Time, and Interval

Next, we need to define our start and end times, along with the interval expressed as a timedelta object.

Step 3: Generate Periods

Now, we’ll create a list to hold our time periods and use a loop to generate the intervals. Here’s how you can do it:

Step 4: Print the Results

To visualize the results, print the periods list.

The periods will be displayed in a list of tuples, where each tuple contains the start and end datetime objects.

Step 5: Format the Output for Readability

If you prefer to display the output in a specific string format, you can define a helper function that formats the datetime objects as follows:

Example Output

The final formatted output will look like this:

Conclusion

By using the datetime module in Python, you can easily break down time ranges into smaller, manageable periods based on an interval. This can be particularly useful for applications in scheduling, event planning, or data logging.
