How Can I Accurately Measure the Execution Time of a Python Program?

Measuring Execution Time of a Python Program

To gauge the precise duration of a Python program's execution, particularly a command line program that demands extended runtime, the following strategies may be employed:

The timeit module offers an effective approach for timing concise code snippets. However, for whole program measurement, consider employing a more comprehensive solution:

import time

# Capture the program's start time
start_time = time.time()

# Execute the program's main function
main()

# Calculate and display the execution time
print("--- %s seconds ---" % (time.time() - start_time))

This method hinges on the assumption that your program consumes at least 0.1 seconds to execute. Moreover, it outputs the execution time in a human-readable format, making it convenient to analyze the program's performance:

--- 0.764891862869 seconds ---
