Python Timer Function: Measure Elapsed Time with Best Examples in Python 2025

👉Python Timer Function: Measure Elapsed Time with Examples

Python Timer Function: Python’s time module provides efficient tools to manage and measure time-related operations. This module includes various functions for tracking performance, computing elapsed time, and handling date-time objects.

👉Key Python Timer Functions

1. time.time() – Tracks elapsed time in seconds.
2. time.sleep() – Pauses code execution for a specified time.
3. time.ctime() – Converts timestamps to readable string format.
4. time.gmtime() – Displays structured time in UTC format.
5. time.process_time() – Tracks CPU processing time for precise performance evaluation.
6. time.thread_time() – Measures active thread execution time.

👉How to Use Python’s time.time() for Elapsed Time

The time.time() function records the current time in seconds since the Unix epoch (January 1, 1970).

👉Python Timer Function Example Code:

python

import time

start_time = time.time()

print(“Starting timer…”)

time.sleep(2)  # Pause for 2 seconds

end_time = time.time()

elapsed_time = end_time – start_time

print(f”Elapsed time: {elapsed_time} seconds”)

👉Output:

css

Starting timer…

Elapsed time: 2.001 seconds

---

👉Using time.sleep() to Delay Code Execution

The time.sleep() function pauses your program for the specified number of seconds.

👉Example Code:

python

import time

print(“Starting delay…”)

time.sleep(3)

print(“Delay completed!”)

👉Output:

arduino

Starting delay…

Delay completed!

---

👉Converting Time to Readable Format with time.ctime()

The time.ctime() function converts timestamps into a human-readable string.

👉Example Code:

python

import time

current_time = time.time()

print(“Current time in human-readable format:”, time.ctime(current_time))

👉Output:

pgsql

Current time in human-readable format: Mon Mar 14 10:30:05 2025

---

👉Tracking CPU Time with time.process_time()

The time.process_time() function is ideal for performance benchmarking.

👉Example Code:

python

from time import process_time

start_time = process_time()

for i in range(1000000):

    pass

end_time = process_time()

print(“CPU process time:”, end_time – start_time)

👉Output:

arduino

CPU process time: 0.025 seconds

---

👉Measuring Thread Execution with time.thread_time()

This function tracks the time spent specifically on active thread execution.

👉Example Code:

python

import time

import threading

def sample_task():

    start_time = time.thread_time()

    for _ in range(10000000):

        pass

    end_time = time.thread_time()

    print(f”Thread execution time: {end_time – start_time}”)

thread = threading.Thread(target=sample_task)

thread.start()

thread.join()

👉Output:

css

Thread execution time: 1.03 seconds
