“How To Schedule A Function To Run Every Hour On Flask?” ~ bbaz
Introduction:
In the world of web development, Flask is one of the most popular Python web frameworks that allows developers to build web applications quickly and efficiently. Flask has gained its popularity due to its simplicity in design, flexibility, and scalability. One of the most useful features of Flask is the ability to automate hourly functions without any external libraries. In this article, we will discuss a step-by-step guide on how to automate hourly functions on Flask without any external libraries.
Basic Requirements:
There are certain requirements that we need to complete before we proceed with automating hourly functions. These requirements include:
- Python 3.x installed on your machine
- Virtual environment installed
- Flask version 1.x installed
Creating a Flask Project:
Creating a Flask project is the first step in building a web application with Flask. The following command should be entered in your CLI to create a new Flask project:
mkdir project_namecd project_namepython3 -m venv venvsource venv/bin/activatepip install flaskExplanation:
The first line creates a new directory with the name of your project. The second line changes your current directory to the project directory. The third line creates a virtual environment for your project, and the fourth line activates the virtual environment. Finally, the fifth line installs the Flask package.
Create a Python Script:
Create a new Python script file within your project directory using your favorite code editor. In our example, we will name our file app.py. Copy the following code into the file:
from flask import Flaskimport datetimeapp = Flask(__name__)@app.route('/')def hello_world(): now = datetime.datetime.now() current_time = now.strftime(%H:%M:%S) return f'Current Time is: {current_time}'if __name__ == '__main__': app.run()Explanation:
This code initializes the Flask application and creates a route at the root of the application. When the user accesses the root page, the function is executed, and the current time is displayed on the screen.
Automating Hourly Functions:
In order to automate hourly functions, you need to use the threading module in Python. The threading module allows us to run multiple threads (smaller parts of code) in parallel. To automate a task hourly, we can use the Python sleep function along with threading.
Create a new Python file clock.py within your project directory using your favorite code editor. Copy the following code:
from threading import Threadimport timedef clock(app): def update_time(): with app.app_context(): while True: print('Updating current time...') time.sleep(3600) thread = Thread(target=update_time) thread.start()Explanation:
The above code initializes the clock function which updates the time every hour. It then creates a thread and starts it. This causes the clock function to run indefinitely in the background.
Integrating Clock Function:
The last step is to incorporate the clock function into our Flask application. Add the following line of code to your app.py file:
from clock import clockclock(app)Explanation:
With this line of code, the clock function will be executed along with your Flask application. It will call every hour and update the time.
Comparison Table:
The table below summarizes the main differences between manual and automated hourly functions:
| Manual | Automated |
|---|---|
| Requires user to manually run code. | Executed automatically after a set interval of time. |
| Requires user interaction. | Runs in the background. |
| Less efficient. | More efficient and less error-prone. |
Conclusion:
In conclusion, automating hourly functions on Flask is simple and can be done without any external libraries. By following the steps outlined in this article, you can update time every hour without requiring any user intervention. This leads to more efficient and less error-prone code.
We hope you found this step-by-step guide on automating hourly functions on Flask helpful! By following these instructions, you can save time and increase accuracy when running repetitive tasks. With a few lines of code, you can automate processes like sending emails or updating data in your database on an hourly basis.
Using Flask and Heroku makes setting up your automated process straightforward and accessible. Flask’s quick, lightweight framework allows you to write simple, clear code that executes faster than other web frameworks. Heroku’s platform is designed to help developers deploy and manage their applications with ease.
Now that you have the tools, it’s time to put them into practice. Experiment with different hourly functions and see how they can enhance your productivity. Remember that automation is not only about saving time but also reducing errors and improving the accuracy of your work. Happy coding!

- What are some common hourly functions to automate on Flask?
Flask is a micro web framework written in Python. It is designed to be lightweight and flexible, making it an ideal choice for building web applications that require rapid prototyping and minimal boilerplate code.
Automating hourly functions can help you save time and reduce errors by eliminating the need for manual intervention. This can be especially useful for tasks like data processing or report generation that need to be run frequently and consistently.
To set up a Flask app, you will need to install Flask using pip and create a new Python file with your application logic. You can then define routes and views to handle incoming requests and render responses.
You can use the Flask-Scheduler extension to schedule functions on a regular interval. This allows you to specify the frequency and timing of your functions, and ensures they run even if your application is restarted or crashes.
Some common hourly functions to automate on Flask include data processing, report generation, and backup tasks. You can also use Flask to schedule periodic emails or notifications, or to integrate with external APIs or services.
