How to Create a Countdown Timer in Python
In this tutorial, we will program 'How to Create a Countdown Timer in Python'. We will learn how to create a proper countdown timer. The main goal here is to create a reliable countdown timer that can be used to time any events. I will provide a sample program to demonstrate the actual coding of this tutorial.
This topic is very easy to understand; just follow the instructions I provide, and you can also do it yourself with ease. The program I will show you covers the basics of programming for creating a countdown timer. I will do my best to provide you with the easiest method of creating this countdown timer program. So, let's start with the coding.
Getting Started:
First you will have to download & install the Python IDLE's, here's the link for the Integrated Development And Learning Environment for Python https://www.python.org/downloads/.
Creating Main Function
This is the main function of the application. The following code will display a simple GUI in terminal console that will display the countdown timer. To do this, simply copy and paste these blocks of code into the IDLE text editor.- import time
- def countdown(time_sec):
- while time_sec:
- mins, secs = divmod(time_sec, 60)
- timeformat = '{:02d}:{:02d}'.format(mins, secs)
- print(timeformat, end='\r')
- print("\n")
- time.sleep(1)
- time_sec -= 1
- print("Timer end")
- while True:
- ret=False
- print("\n\n=============== Countdown Timer ===============\n\n")
- sec=int(input("Set your timer in sec: "))
- countdown(sec)
- user_input=input("\n\nTry Again? (Yes/No): ")
- if user_input.lower()=='no':
- print("Exit program.")
- break
- elif user_input.lower()=='yes':
- ret=True
- else:
- print("Wrong input.")
- ret=True
- if ret:
- continue
In the provided code, we simply enclosed the code with a while loop to allow for continuous execution of the program. We will create a method that will set the timer based on the input you provide. You just need to call the method in order to display the timer.
