Anaconda is a very popular distro of Python, which provides a convenient package Manager Conda, a few pre-installed versions of Python (2.7, 3.4 and 3.7) and the development environment IDLE Spider and many libraries that are easy to install. Yet there is a library to handle Big Data, predictive Analytics, and scientific computing. You can also manage everything via a graphical utility, Anaconda Navigator.
In this article, we’ll look at how to download and install Anaconda Python Ubuntu 18.04 from the official website of the program, and how to prepare the platform for operation.
Anacoda to install in Ubuntu

You can download the program directly in the browser or copy the link to download via wget. For example, for the current version of the command will look like this:
Since it is quite a large file, after the download is complete it is advisable to check it on control points. To find the checksum of the downloaded file with the command:
Then, it must compare with total shown on this page are for your version of the program. If the resulting values match, then all right.
Next, run the script:
In the first step of the installation press Enter, then type yes to accept the license agreement:

conda init bash
Then run the following command to read settings:
Now you can check if everything works by running the following command:
The Anaconda installation of Ubuntu completed.
2. Update Anaconda
Update Anaconda is also quite simple to perform. You must first update the conda tool. To do this, run:
conda update conda
On programme questions, answer y. When the update has completed, you can upgrade the Anaconda 3:
conda update anaconda
Like the previous item, press yto continue the update.
3. Environment Conda
As I said, Сonda is a package Manager, and this Manager environments. You can create multiple environments with different Python versions, and with different installed libraries. View the list of available environments with the command:
conda info --envs
To activate the environment, use the command activate. For example, do active environment base:
conda activate base
You can also create a new environment with a different version of Python. For example do environment with Python 3.5:
conda create --name ptn35env python=3.5
The program will create the environment and let you know which packages it is necessary to install, accept the installation:
Then activate the desired environment:
conda activate ptn35env
To deactivate the current environment, use the deactivate command:
To remove the environment ptn35env, you need to use the uninstall command and remove:
conda remove --name ptn35env -all
4. Install the packages Conda
View the list of installed packages with the list command:
To find the desired package, use search, for example, looking for package Manager Python – pip:

To remove the Anaconda from his system, enough to run the following commands:
Open the file ~/.bashrc and delete out the lines added Anaconda usually are between tags conda initialize:
Then delete the hidden folders with additional files and configuration platforms:
rm-rf ~/.condarc ~/.conda ~/.continuum
Now install Anaconda on Ubuntu completed. You can start using the package Manager Conda, use of virtual environments in Python and easy to install packages. We discussed only the basics of using conda to study better, read the official documentation.
