Install Python

CCDciel include a Python scripting interface.

For simple script it is sufficient to use the default Python included with Linux or installed by CCDciel on Windows. In this case you can ignore the end of this page..

But if you use a Mac or want a more advanced usage that need to install specific astronomy modules, you can follow the instructions below

Windows

Download the Python installer from https://www.python.org/downloads/windows
Get the last stable installer corresponding to your system, for example Windows installer (64-bit)
Run the downloaded installer and click on “Install Now”, follow the next steps to the end.

Open a command line prompt to use pip to install the additional modules you need.
For example:
```
py -m pip install astropy astroplan matplotlib numpy requests pyserial tk
```

In CCDciel preference change the Python command to py.exe

macOS

Old Mac version used to provide a Python version 2, this is not suitable for our use. New macOS do not provide anything. In all case you need to install Python 3 as describe below.

Download the Python installer from https://www.python.org/downloads/macos, Get the last stable universal installer.
Open the downloaded installer, follow the steps to the end.
Open a command line prompt to create a virtual environment:
```
python3 -m venv ~/.venvs/astro
```
Activate the environment:
```
source ~/.venvs/astro/bin/activate
```

From the same activated shell install the modules you need:

pip3 install astropy astroplan matplotlib numpy pyserial tk

In CCDciel preference change the Python command to:
/Users/{username}/.venvs/astro/bin/python3

Linux

On Linux Python and many modules are already installed with the system.
If you want more, the best is to create a virtual environment to install the additional modules.

Create the virtual environment:
```
python3 -m venv ~/.venvs/astro
```
Activate the environment:
```
source ~/.venvs/astro/bin/activate
```

From the same activated shell install the modules you need:

pip3 install astropy astroplan matplotlib numpy pyserial tk

In CCDciel preference change the Python command to:
/home/{username}/.venvs/astro/bin/python3
