+
+Maybe you don't need `pyenv` and/or `virtualenv` in most cases.
+
+## Install Python
+
+> Don't have `brew`? Go to <https://brew.sh>.
+
+```
+brew install python3
+```
+
+If you still need Python 2, run `brew install python`.
+
+## Install Jupyter Notebook
+
+```
+pip3 install jupyter
+python3 -m ipykernel install --user
+```
+
+You also want Python 2 kernel, so then:
+
+```
+pip install ipykernel
+python -m ipykernel install --user
+```
+
+That's all.
+
+# How about `virtualenv`?
+
+Since Python 3 got its own virtual environment tool called [venv](https://docs.python.org/3/library/venv.html), You no longer need `virtualenv` itself.
+
+If you want a virtual envs on your project, run:
+
+```
+python3 -m venv venv
+source ./venv/bin/activate
+```
+
+then `venv` will creates virtual envs on **./venv** folder on the root of your project.
