pip install dependencies only

Sure, let's create a simple tutorial on installing Python dependencies using pip with code examples. In this tutorial, we'll cover the basics of creating a virtual environment, installing dependencies from a requirements file, and upgrading packages.
A virtual environment is a isolated Python environment for your project. It helps manage dependencies without interfering with system-wide packages.
Use pip to install the dependencies listed in the requirements file:
This command installs all the dependencies along with their specified versions.
To verify that the packages were installed successfully, you can check the installed packages:
This command lists all installed packages along with their versions.
To upgrade packages to the latest versions, use:
This command upgrades all the packages to the latest versions specified in the requirements file.
When you're done working on your project, deactivate the virtual environment:
This ensures that your system environment is not affected by the project's dependencies.
