Creating "Hello World" with Flask [Python Framework] on A SMARTPHONE


Python Class



Creating a simple "Hello World" application using Flask in Pydroid 3:


1. Install Pydroid 3 from Play Store.


2. Open the app and locate the "Terminal Button" and tap it to open a dark phase side of the app. Then, write/code:


pip install flask


Wait for the installation process to complete.


3. Then, go back to the project side that is usually in the light phase and create a new file. Name the file as "app.py". In this file, write/code:


from flask import Flask 

app = Flask(__name__) 


@app.route("/") def hello(): return "Hello, World!" 


if __name__ == "__main__": app.run(debug=True) 


4. Save the changes and go to the terminal and write/code:


python app.run


5. Run it by tapping the Enter Key of your keyboard and wait for it to load. A temporary local host; http://127.0.0.5000 will be generated. Tap the local host, you will be redirected to choose a browser. Choose and wait for it to load the "Hello World."


This is the simplest way to create/write "Hello World" with Python using Flask Framework on Smartphone.
