how to make a timer using python

1import time					
2tic = time.perf_counter() # Start Time
3your_program() 			  # Your code here
4toc = time.perf_counter() # End Time
5# Print the Difference Minutes and Seconds
6print(f"Build finished in {(toc - tic)/60:0.0f} minutes {(toc - tic)%60:0.0f} seconds")
7# For additional Precision
8print(f"Build finished in {toc - tic:0.4f} seconds")

1import time, os
2
3seconds_to_go_for = 10 # How long the timer will go for
4current_time = int(time.time()) # Gets the time before the timer starts

6def clear():
7  if os.name == "nt":
8    os.system("cls") # Clear function, to avoid spam. Source: geeksforgeeks.org
9  else:
10    os.system("clear")
11
12while True:
13  time_now = int(time.time()) # Gets time during the timer's running
14  if time_now >= current_time + seconds_to_go_for: # Checks if enough time has passed
15    break # Stops loop if so
16  
17  print(f"Seconds passed: {time_now - current_time}") # Prints how much time has passed
18  clear()
19print("The timer has ended")

2    print "hello, world"
3
4t = Timer(30.0, hello)
5t.start() # after 30 seconds, "hello, world" will be printed

1# The simplest way to create a timer is to use time.sleep and winsound
2import winsound

4sec_time = min_time * 60 
5time.sleep(sec_time)
6#Now for the sound, I'll use winsound.beep. You can use whatever you want
7# Frequency is hoiw high or low pitched the sound to be (It's measured in Hz)
8frequency = 500
9# Duration is measured in milliseconds here. 1 second = 100 milliseconds
10duration = 100
11# I want it to beep 5 times, so I'll create a for loop.
12for i in range(0,5):
13    winsound.Beep(frequency,duration)
