The time module
The time module allows the user to directly get the time, in seconds, since 1970 (See: https://docs.python.org/3/library/time.html). This means that we can subtract the time before from time after to see how long it has been, namely how long it took the user to finish the typing test. From there, it is as easy as printing the result. You can round the time using int to get a purely seconds result without milliseconds.
The code
# Import the time library
import time
# Calculate the start time
start = time.time()
# Code here
# Calculate the end time and time taken
end = time.time()
length = end - start
# Show the results : this can be altered however you like
print("It took", length, "seconds!")

You can use the built-in time library:
import time
str_to_type = "The cat is catching a mouse."
start_time = time.perf_counter()
print("Type: '" + str_to_type + "'.")
typedstring = input()
if typedstring == str_to_type:
end_time = time.perf_counter()
run_time = end_time - start_time
print("You typed '" + str_to_type + "' in", str(run_time), "seconds.")

March 23, 2022Count down timer Python
You need to re-calculate the time inside your loop. I am going to use the datetime.timedelta object to hold the time difference; it makes the calculation simpler and more reliable. https://docs.python.org/3/library/datetime.html#timedelta-objects >>> import time >>> event_time = datetime.datetime(2041, 10, 4, 0, 0) >>> remaining_time = event_time - datetime.datetime.now() >>> while remaining_time.seconds > 0: ... remaining_time = event_time - datetime.datetime.now() ... print("{} Years, {} days, {:02d}:{:02d}".format(remaining_time.days//365, remaining_time.days%365, remaining_time.seconds//3660, (remaining_time.seconds//60)%60)) ... time.sleep(10) ... 19 Years, 200 days, 13:04 19 Years, 200 days, 13:04 19 Years, 200 days, 13:03 19 Years, 200 days, 13:03 19 Years, 200 days, 13:03 19 Years, 200 days, 13:03 19 Years, 200 days, 13:03 19 Years, 200 days, 13:03 19 Years, 200 days, 13:02 More on reddit.com

One advantage of using the @contextmanager decorator to define our timer is that we can use the timer both using the with statement and as a function decorator, like in the last example. If we wanted to time a certain operation once, we could call in timer() using a with statement.

September 27, 2022 - Within the loop, we use the timedelta() function to calculate the time left on the timer. The program prints the time left in hours:minutes:seconds format for the user to see. Immediately after, the program pauses for one second, reduces total_seconds by one second, and repeats the while loop. The loop continues until total_seconds reaches zero, at which point the program leaves the while loop and prints “Bzzzt! The countdown is at zero seconds!” · You can use Python to measure the time it takes for a program to finish execution.

Hello guys ! I’m starting with python a week ago, I don’t have all the knowledge etc…, but I’m very curious and I wish to know a method or how to make a Timer in python… like my timer start at 35min and decrease to 0 or to 0 to 35. If anybody have an idea how to do this, I'll take it !! See you ! 🐍

The simplest way would be to simply loop for the required number of minutes, and "sleep" for one minute before the next loop. Here is an example counting down in seconds: from time import sleep def countdown(num): for n in range(num, 0, -1): print(n) sleep(1) print("Blast off!") While this may be accurate enough for a few loops, it will run a little bit slower than intended, because each loop takes a little over 1 second (sleep for 1 second + time to print + time to loop). The error is cumulative, so the timer will gradually get later the more times that it loops. To avoid this potential issue, you need to use the same time reference for every loop. Here is an example: from time import time, sleep def countdown(num): print_time = time() for counter in range(num, 0, -1): print(counter) print_time += 1 # wait until elapsed time reaches print_time. while time() < print_time: sleep(0.001) print("Blast off!")
Python

time — Time access and conversions
On Windows, if secs is zero, the thread relinquishes the remainder of its time slice to any other thread that is ready to run. If there are no other threads ready to run, the function returns immediately, and the thread continues execution. On Windows 10 and newer the implementation uses a high-resolution timer which provides resolution of 100 nanoseconds.

Yes. But if you want to make it shorter you have to type faster :slightly_smiling_face:; you are also measuring how long it takes you to type the directory name. start = time.time() is before you ask for the directory name.

I see your point. :slight_smile:
After moving start = time.time(), I get 0.0001838207244873047.

How to create a timer in Python
Countdown timers: These timers are established with a designated time duration that diminishes until the timer reaches zero. They are commonly used to create time limits, implement timeouts, schedule reminders, or trigger actions at specific points in time. Python offers the option to construct timers from scratch using either the threading module or the time module.
