In this project, we will be using the time module and its sleep() function. Follow the below steps to create a countdown timer:

Step 1: Import the time module.

Step 2: Then ask the user to input the length of the countdown in seconds.

Step 3: This value is sent as a parameter 't' to the user-defined function countdown(). Any variable read using the input function is a string. So, convert this parameter to 'int' as it is of string type.

Step 4: In this function, a while loop runs until time becomes 0.

Step 5: Use divmod() to calculate the number of minutes and seconds. You can read more about it here.

Step 6: Now print the minutes and seconds on the screen using the variable timeformat.

Step 7: Using end = '\r' we force the cursor to go back to the start of the screen (carriage return) so that the next line printed will overwrite the previous one.

Step 8: The time.sleep() is used to make the code wait for one sec.

Step 9: Now decrement time so that the while loop can converge.

Step 10: After the completion of the loop, we will print "Fire in the hole" to signify the end of the countdown.
