Prerequisites

Before installing python 3.7 there are some dependencies that we need to install. Use the following command to install the required dependencies.

sudo apt-get install -y build-essential tk-dev libncurses5-dev libncursesw5-dev libreadline6-dev libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev libffi-dev

2. Install Python 3.7 On Raspberry Pi

Now we will extract and install Python from the source.
sudo tar zxf Python-3.7.0.tgz
cd Python-3.7.0
sudo ./configure
sudo make -j 4
sudo make altinstall

4. Make Python 3.7 as the default version

If you want to use python 3.7 as a default version you can create an alias.

Let’s check the path of Python.

vim ~/.bashrc

alias python='/usr/local/bin/python3.7'

Then source the .bashrc file.

source ~/.bashrc

If the path of Python is not /usr/local/bin/python3.7 the use which to get the path of python.
which python3.7
/usr/local/bin/python3.7
and then follow the Step 4 again.

5. Check Python Version

After creating an alias check the python version again.

python -V
Python 3.7.0

Now you have successfully installed Python 3.7 on Raspberry Pi.

    • Hey Joie,

      Thanks for your message. I like to use vim so I write to use the vim. You can feel free to use any other editor of your choice.

  1. When we do the above steps, every time the system turn on it will go into python environment instead of system environment. May I know if there is anywhere to undo the above, ie remove the modification in ./bashrc?
    so that at bootup, it will becomes at the prompt of
    pi@raspberrypi: etc

    appreciate you advice in this as I ma new to raspberry

  2. This is due to the fact that you added to .bashrc file the following lines:
    which python3.7
    /usr/local/bin/python3.7

    If you remove that you will not have that behaviour.

  3. hang on! I’m stuck in python, How do I get a normal terminal back so I can do this?
    “This is due to the fact that you added to .bashrc file the following lines:
    which python3.7
    /usr/local/bin/python3.7”

    As I’m stuck in python!

    • Hey John,
