You have 3 conda download options:
You can download any of these 3 options with legacy Python 2.7 or current Python 3.
You can also choose a version with a GUI or a command line installer.
If you are unsure which option to download, choose the most recent version of Anaconda3, which includes Python 3.6, the most recent version of Python. If you are on Windows or macOS, choose the version with the GUI installer.
Choose Anaconda if you:
Are new to conda or Python.
Like the convenience of having Python and over 150 scientific packages automatically installed at once.
Have the time and disk space---a few minutes and 300 MB.
Do not want to individually install each of the packages you want to use.
Choose Miniconda if you:
Do not mind installing each of the packages you want to use individually.
Do not have time or disk space to install over 150 packages at once.
Want fast access to Python and the conda commands and you wish to sort out the other programs later.
Both GUI and command line installers are available for Windows, macOS, and Linux:
If you do not wish to enter commands in a terminal window, choose the GUI installer.
If GUIs slow you down, choose the command line version.
The last version of Python 2 is 2.7, which is included with Anaconda and Miniconda.
The newest stable version of Python is 3.7, which is included with Anaconda3 and Miniconda3.
You can easily set up additional versions of Python such as 3.5 by downloading any version and creating a new environment with just a few clicks. See Getting started with conda.
