How Can I Efficiently Measure the Total Execution Time of My Python Program?

Measuring Execution Time of Python Programs

In Python, quantifying the execution time of a program is a common requirement, particularly for performance optimization and debugging purposes. This article addresses the specific challenge of measuring the total execution time of a Python script.

While the timeit module is efficient for timing small code snippets, it's not suitable for measuring the runtime of an entire program. Hence, we present a straightforward approach using the time module:

import time

# Record the start time
start_time = time.time()

# Execute the main program logic
main()

# Get the elapsed time
elapsed_time = time.time() - start_time

# Print the result
print("--- %s seconds ---" % elapsed_time)

This approach assumes that your program takes at least a tenth of a second to run. The elapsed time is then printed in seconds, accounting for the time it takes to execute the entire script. This method provides a clear and concise way to determine the total execution time of your Python programs.
