python virtual environment windows | How to install python and activate environment смотреть онлайн

Creating a Python virtual environment is a useful way to isolate and manage your Python project's dependencies. To create a Python virtual environment, follow these steps:

Open a Terminal (Command Prompt on Windows): You'll need to use a command-line interface to create the virtual environment.

Navigate to Your Project Directory: Use the cd command to navigate to the directory where you want to create the virtual environment. For example:

bash
Copy code
cd path/to/your/project
Create the Virtual Environment: Use the python -m venv command followed by the name you want to give to your virtual environment. Replace env_name with your chosen name:

bash
Copy code
python -m venv env_name
For example:

bash
Copy code
python -m venv myenv
Activate the Virtual Environment:

On Windows:

bash
Copy code
env_name\Scripts\activate
On macOS and Linux:

bash
Copy code
source env_name/bin/activate
After activation, your terminal prompt should change, indicating that you are now working within the virtual environment.

Install Dependencies: Inside the activated virtual environment, you can use pip to install Python packages and dependencies specific to your project.

Deactivate the Virtual Environment: When you're done working in the virtual environment, you can deactivate it:

bash
Copy code
deactivate
This will return you to your system's global Python environment.

That's it! You've successfully created a Python virtual environment and can now manage your project's dependencies separately from your system-wide Python installation.
