Virtual environment (pipenv)

Python has another tool that name is Pipenv. This tool combines pip and Venv to the one tool. Pipenv for python like npm for javascript.

pip install pipenv

Then

pipenv install request

For activate a virtual environment

pipenv shell

For deactivate

exit

When we use pipenv for virtual environment it create two file in the project directory with name "Pipfile" and "Pipfile.lock". When you want to move the project to another computer you can use this file to install the dependency of the project.

If you want to install dependency with the latest version that release you should use Pipfile

pipenv install

But if you want to install dependency with specific version you should use Pipfile.lock

pipenv install --ignore-pipfile

If you want to know about the dependency of the package you can use the below command

pipenv graph
