You can install Flask using the pip command in Python 3 by following these steps:

Open a command prompt or terminal window on your computer.

Make sure you have Python 3 installed. You can check the Python version by running the following command:

css

python --version
If you have Python 3 installed, the output should show the version number (e.g., 3.x.x). If you don't have Python 3 installed, you can download and install it from the official Python website (https://www.python.org/).

Once you have Python 3 installed, you can install Flask using the pip command. Pip is a package manager for Python that allows you to install third-party libraries. Run the following command:

pip install flask
This will download and install the Flask library along with its dependencies.

After the installation is complete, you can verify that Flask is installed by running the following command:

pip list
This will display a list of installed packages, and Flask should be listed among them.

That's it! You have successfully installed Flask using the pip command in Python 3. You can now start using Flask to build web applications in Python.
