virtualenv environments (and optionally doesn’t access the globallyinstalled dependencies either). You can even configure what version of Pythonyou want to use for each individual environment. It's very much recommended touse virtualenv when dealing with Python applications.

It will get installed in the
venv/ folder, and not conflict with otherprojects.
To leave the virtual environment run:
Important: Remember to add
venv to your project's .gitignore file soyou don't include all of that in your source code.
![]()
It is preferable to install big packages (like Numpy), or packages you alwaysuse (like IPython) globally. All the rest can be installed in a

Virtualenvwrapper
To make it easier to work on multiple projects that has separate environmentsyou can install
