When programming in Python, you may sometimes want to pause the execution of your script for a short period of time, such as one second. This can be useful for a variety of reasons, such as displaying information to a user, throttling requests to a server, or simulating real-world processes that take time to complete. In this blog post, we’ll explore how to make Python wait for one second using the time.sleep() function.
Using the time Module
The time module is part of Python’s standard library and provides various functions for working with time. One such function is time.sleep(), which causes the program to pause for a specified number of seconds. To make Python wait for one second, we can simply call the time.sleep() function with an argument of 1:
import time print("Starting script...") time.sleep(1) print("...1 second later.")
When you run the above script, you’ll notice that there is a pause of one second between the output of the two print() statements. This is because the time.sleep(1) line causes the script to pause for one second before proceeding to the next line.
Using time.sleep() in Loops
You can also use the time.sleep() function within loops to create recurring delays. For example, let’s say you want to create a simple countdown timer that starts at 5 and counts down to 1, with a one-second pause between each number. You could achieve this by using a for loop and the time.sleep() function:
import time for i in range(5, 0, -1): print(i) time.sleep(1) print("Time's up!")
When you run the above script, you’ll see the numbers 5 through 1 displayed on the screen, with a one-second pause between each number. After the countdown reaches 1, the message “Time’s up!” is displayed.
In this blog post, we demonstrated how to make Python wait for one second using the time.sleep() function from the time module. This powerful function allows you to easily pause your script for a specific duration, making it simple to add delays, implement countdowns, or throttle requests in your Python programs. Happy coding!
