No module named flask

It seems like you're encountering an error related to the Flask module. The error message "No module named flask" indicates that Flask is not installed in your Python environment.

To resolve this issue, you can follow these steps:

1. Open your command prompt or terminal.
2. Create a virtual environment (optional but recommended):

   python -m venv myenv

3. Activate the virtual environment:
- For Windows:

     myenv\Scripts\activate

- For macOS/Linux:

     source myenv/bin/activate

4. Install Flask using pip:

   pip install flask

5. Once the installation is complete, you should be able to import Flask in your Python script without any errors.

Make sure you have a stable internet connection during the installation process. If you already have Flask installed but are still encountering this error, try updating Flask to the latest version by running `pip install --upgrade flask`.
