How to Run Your Web App using Flask in Pycharm Community Edition

 I'd be glad to guide you through installing Flask in PyCharm Community Edition:

Method 1: Using PyCharm's Package Installer

1. Open your PyCharm project or create a new one.

2. Navigate to File -> Settings (or Preferences on macOS).

3. Go to Project: [Your Project Name] -> Project Interpreter.

4. Click the green "+" button in the top right corner to install a new package.

5. Search for "Flask" in the search bar.

6. Select "Flask" from the results and click "Install Package".

PyCharm will download and install Flask for your project's virtual environment (if you're using one).

Method 2: Using the Terminal

1. Open a terminal window on your system.

2. Activate your project's virtual environment (if you're using one). You can usually do this by running a script or command provided by your virtual environment manager (e.g., source venv/bin/activate for a virtual environment created with venv).

3. Run the following command to install Flask using pip:

   Bash

   pip install Flask
   

Verifying Installation

Once you've installed Flask using either method, you can verify it by creating a simple Python script:

1. Create a new Python file in your project (e.g., app.py).

2. Add the following code to your script:

from flask import Flask

app = Flask(name)

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

if name == "main": app.run(debug=True)

3. **Run the script** from PyCharm or the terminal.

- In PyCharm, right-click on the `app.py` file and select "Run 'app.py'".
- In the terminal, navigate to your project directory and run `python app.py`.

4. **Open your web browser** and go to `http://127.0.0.1:5000/` (or the address specified by `app.run`). You should see "Hello, World!" displayed.

This confirms that Flask is successfully installed and working in your PyCharm project.
