How to update Python in Ubuntu?

Question

Can anyone tell me how to update Python in Ubuntu?

Answer 1

For updating Python in Ubuntu, first of all, you need to download PPA as this file is having the current version of Python. To download PPA, you can use the below code:

$ sudo add-apt-repository ppa:deadsnakes/ppa

After downloading and installing PPA, the next thing is to update the packages. For updating, you can execute the below command:

$ sudo apt-get update

Now, the main task is to update the version from Python 2x to Python 3x. You can use the following code for that:

$ sudo apt-get install Python3.6

$ sudo apt-get install Python3.7

After installing Python 3x, now, you should install pip using the below code:

$ sudo apt install Python3-pip

Finally, you have to set the priority for both Python 3.6 and Python 3.7 using the following:

$ sudo update-alternatives --install /usr/bin/Python3 Python3 /usr/bin/Python3.6 1

$ sudo update-alternatives --install /usr/bin/Python3 Python3 /usr/bin/Python3.7 2
