Failed to start -.-

I understand you frustration, I have had this exact problem with Python a few times myself :(

Personally I find the way Python uses indentation to be helpful writing short bits of code, but clunky and error-prone for larger bits of code like this. It does not help that different editors do different things with tab characters.

As for copying code or other files between a Raspberry Pi and a Windows machine, I usually create a network share in Windows and mount that share on the Pi. It is not hard to do, but you will need to run the command to mount the share each time the Pi has been restarted.

First you will need to create a directory to mount the Windows share to. I usually create mine in the /mnt directory like this:

sudo mkdir /mnt/windows
sudo chown pi /mnt/windows

You only need to do this the first time, the next time the directory will already exist.

You can then run a rather long command to mount the Windows share onto this directory:

sudo mount.cifs //192.168.0.100/SHARENAME /mnt/windows -o rw,noperm,username=USERNAME

but replace:

• 192.168.0.100 with the IP address of the Windows machine
• SHARENAME with the name of the Windows share
• /mnt/windows with the directory you created
• USERNAME with your Windows username

When you run the mount.cifs command it will ask for your Windows password to access the share. After that you can then copy to and from the /mnt/windows directory like any other one on the Pi :)

I will be looking at all of the entries which did not work sometime later tomorrow. I will confirm with you if the indentation is indeed the cause of problem.

If you're working command line on the Pi, then a very useful utility to install is 'mc' (Midnight Commander): it's a text based file management system very similar to an old DOS application called 'XTree' for the days of yore.

install it with

sudo apt install mc

and just run it with mc

It's extremely useful for when you've got an external drive mounted because it has two panes for you to copy between.

One of the first things I tend to install on a headless machine.
