![]() ![]() Each thread prints and then waits for 1 second before printing again. In this example, we have two threads that run concurrently. # (After a 1 second delay, the program prints.) Threading.Thread(target=print_letters).start() Threading.Thread(target=print_nums).start() This can be achieved using the time.sleep() function in the relevant thread. In a multi-threaded program, you might want one thread to wait while the other threads continue their execution. This way, we manage to introduce a delay in each iteration. In each iteration, it prints the current iteration number and then waits for 2 seconds before proceeding to the next iteration. In this example, we have a loop that iterates five times. # (After a 2 second delay, the program prints.) Time.sleep(2) # Makes Python wait for 2 seconds in each iteration This can be achieved by placing the time.sleep() function inside the loop. In some cases, you might want your Python program to wait for a certain duration in each iteration of a loop. Two such scenarios involve using the wait function in loops and alongside threading. Python Wait in Loops and ThreadingĪs we delve deeper into the Python wait function, we uncover its potential in more complex scenarios. While it’s a powerful tool for controlling the flow of your program, it should be used wisely to avoid creating programs that are unresponsive or slow. This is a key point to keep in mind when using time.sleep(). But if your Python program is single-threaded, it will be completely unresponsive while it’s sleeping. This means that if you have a multi-threaded program and one thread goes to sleep, the other threads continue executing. However, it’s important to note that while Python is sleeping, it’s not doing anything else. The time.sleep() function is straightforward and easy to use, which makes it perfect for beginners. After the wait, Python prints ‘Hello, World!’. Then, we use the time.sleep() function to make Python wait for 3.5 seconds. ![]() In this example, we first import the time module. # (After a 3.5 second delay, the program prints.) Time.sleep(3.5) # Makes Python wait for 3.5 seconds This argument can be an integer or a float, which means you can make Python wait for a precise amount of time, right down to the millisecond. The time.sleep() function takes one argument: the number of seconds that you want Python to wait. This function is part of Python’s time module and is your go-to tool for pausing the execution of your Python scripts. Python Wait 101: The time.sleep() FunctionĪt the heart of making Python wait is the time.sleep() function. Wrapping Up: Mastering the Python Wait Function.Real-World Applications of Python Wait Function.Troubleshooting Python Wait: Common Issues and Solutions.Exploring Asynchronous Waiting in Python.Python Wait 101: The time.sleep() Function.Continue reading for a more detailed understanding and advanced usage scenarios. This is a basic way to make Python wait, but there’s much more to learn about controlling the flow of your Python programs. The argument to sleep() is the number of seconds that Python should wait. In this example, we import the time module and use the sleep() function to make Python pause for 5 seconds. # (After a 5 second delay, the program continues.) Time.sleep(5) # Makes Python wait for 5 seconds This function makes Python wait for a specified number of seconds. ![]() To pause or delay execution in Python, you can use the sleep() function from Python’s time module: time.sleep(5). Let’s get started! TL DR: How Do I Make Python Wait or Pause in My Code? We’ll cover everything from the time.sleep() function, to more complex uses such as using it in loops or with threading, and even alternative approaches. In this guide, we’ll walk you through the process of using the Python wait function, from the basics to more advanced techniques. Many developers find themselves in need of this feature, but Python, like a well-timed comedian, has the ability to pause its execution – using the wait function. Ever found yourself in a situation where you needed your Python program to take a breather, or wait for a specific duration? You’re not alone. ![]()
