createeeee aaaa flask server in python

To create a Flask server in Python, follow these steps:

1. Install Flask: Before creating a Flask server, you need to install the Flask package in Python. You can install it using pip. Open your terminal/command prompt and type:

main.py
pip install Flask

2. Import the Flask package: The first step in creating a Flask server is to import the Flask package in your Python code. You can do this using the following line of code:

main.py
from flask import Flask
24 chars
2 lines

3. Create an instance of the Flask class: After importing the Flask package, you need to create an instance of the Flask class. This instance will be the main application object. You can create it using the following line of code:

main.py
app = Flask(__name__)

2 lines

4. Define routes: A route is a URL pattern that the application will respond to. You can define a route using the @app.route decorator. For example, if you want to create a route for the home page, you can do it like this:

main.py
@app.route('/')
def home():
    return 'Hello, World!'

4 lines

5. Run the application: Finally, you need to run the application using the run() method of the Flask class. You can do it like this:

main.py
if __name__ == '__main__':
    app.run()

3 lines

Here's the complete example code for creating a simple Flask server:

main.py
from flask import Flask

app = Flask(__name__)

@app.route('/')
def home():
    return 'Hello, World!'

if __name__ == '__main__':
    app.run()

Save this code to a Python file (e.g., app.py) and run it using the command python app.py. You should see the message "Hello, World!" printed on the console.
