 Analog to managing python versions, `pipenv` can manage pip and package versions.

+### Manual Installation
+
+This section is based on a guide by [Linuxize](https://linuxize.com/post/how-to-install-python-3-9-on-ubuntu-20-04/).
+
+On [Linux-based systems](/wiki/linux.md) Python can be easily installed using make.
+The following shows a process of installing Python 3.9.1.
+When another Python version is needed the version number has to be adapted accordingly.
+
+First make sure all the dependencies are installed.
+On a [Ubuntu](/wiki/linux.md#distributions) system or other systems using the apt
+[package manager](/wiki/linux/package_manager.md) this can look like the following
+
+```sh
+sudo apt update
+sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev libsqlite3-dev wget libbz2-dev
+```
+
+Afterwards the python source code can be downloaded.
+
+```sh
+wget https://www.python.org/ftp/python/3.9.1/Python-3.9.1.tgz
+tar -xf Python-3.9.1.tgz
+cd Python-3.9.1
+```
+
+Afterwards if OpenSSL should be enabled for Python uncomment all the corresponding lines in
+`Modules/Setup`.
+
+Then proceed with the installation.
+
+```sh
+./configure --enable-optimizations
+make
+sudo make altinstall
+```
+
+Afterwards you can check if the Pyhton version is installed using the following command.
+
+```sh
+python3.9 --version
+```
