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.")

Since we have roughly established how to calculate the elapsed time, we can refine our code a little. Python's time module offers us alternatives to the time() function, all reporting the time in seconds but in different ways.

This depends on your code logic. But from the code supplied, most probably it is Timer from threading module, so you just have to add this at the top of your code
from threading import Timer
Documentation is here: threading.Timer

Even though this is probably not the case here given the context, it is also possible that the Timer is from the timeit module which allows to run tests on the quickness of execution.
That is, from timeit import Timer

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.

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 ! 🐍

sounds like you can use the time, module for this or schedule module along with time coukd work as well. Im still a beginner too. https://www.geeksforgeeks.org/python-time-module/

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!")

I have a computer science gcse project and part of it is creating a timer alongside a test to time the user on how long they take to complete it which that data is then transferred into a dedicated file. I’ve gotten no further then creating the time module, does anyone have any advice on how to start the timer/ stopwatch and then check how long a task took to do? I don’t mind I don’t mind whether it’s in min or sec.

Here’s one idea: start_time = time.time() Returns number of seconds since the epoch(beginning of time, me thinks) time_limit = 120 * 60 120 minutes (seconds * 60) Then, later on in your while loop(assuming you have one for constant progress) elapsed_time = time.time() - start_time if elapsed_time > time_limit: here you might punish the user.

The most bare bones way might be to use time.perf_counter() and a pair of input()'s, one to say when to start and one to say when to stop. Get the counter value after the start and again after the stop, and subtract to get the elapsed time. https://docs.python.org/3/library/time.html#time.perf_counter
