To calculate the runtime of your Python code, you can use the 'time' module of Python. This module contains functions that measure the time taken to perform the instructions. You can import the time module in your Python code and use the 'time.perf_counter()' function to determine the time taken to execute that particular block of code. This is a function that calculates the current time in seconds. To calculate the runtime of a Python code, you can use the following steps: 🔹Import the time module. 🔹Start time by calling time.perf_counter(). 🔹Run the block of code that you want to measure its execution. 🔹Finally, call the time.perf_counter() function to stop the timer. 🔹Start time minus the end time equals the runtime. ❗Sample Code <code> import time def my_function(): # put some instruction pass start_time = time.perf_counter() my_function() # call the function end_time = time.perf_counter() runtime = end_time - start_time print("The runtime is:", runtime) </code> Here are some examples of when you might want to measure the runtime : 🔸Your code runs slower and needs identification of performance bottlenecks. 🔸When you start making changes to code you want to make sure, it doesn't affect the runtime. 🔸The efficiency of different Python code implementations. You can use these runtime measurements to improve the performance of your Python code.
