You have splitted your code into multiple functions, documented them, written the usual if __name-- == 'main': test : this is already a pretty good beginning.

Also, pep8 only complies about some whitespaces not following the Python Style Guide (this is worth fixing it anyway).

• your code can be python 3 compliant by adding parenthesis in your calls to print.
• you have the same typo rorate in multiple places
• list is a bad name for a list as you can easily mix-up with the type
• your function and variable names does not follow the convention.

In Programming Pearls (sorry I couldn't find the relevant full text), Jon Bentley describes different solutions to the problem. Some behind quite original and actually very easy to implement on top of being efficient. I'll let you google "programming pearls rotate" if you want to read more about this. It is defintly worth a read (and the whole book is too).

And more generally

            ...
            copy_digit(lst, i + 1, item_to_shift)
            ...

            ...
            lst[i + 1] = item_to_shift
            ...

...
copy_digit(lst, i + 1, item_to_shift)
...

...
lst[i + 1] = item_to_shift
...

Then, it seems like the item_to_shift variable is not really required anymore :

for i in range(len(lst) - 2, -1, -1):
    lst[i + 1] = lst[i]
