	2	+
	3	+	__Python Virtual Environments__ are a tool used to create isolated spaces on your computer where you can install
	4	+	and manage different versions of Python, as well as their respective packages, without affecting
	5	+	the global system installation. This isolation helps avoid version conflicts between projects that
	6	+	require different dependencies or libraries.
	7	+
	8	+	Here's an in-depth look at how they work:
	9	+
	10	+	### Why Use Virtual Environments?
	11	+
	12	+	- Isolation: Each virtual environment is independent of others, ensuring no interference occurs between projects with conflicting requirements.
	13	+	- Dependency Management: It allows you to manage dependencies for a specific project without affecting other projects or the system's Python installation.
	14	+	- Reproducibility: By using virtual environments, it becomes easier to replicate your development environment on another machine or share with others.
	15	+	- Safety: It prevents accidental modification of global packages and allows you to experiment without risking the system's Python installation.
