IndentationError on build_cells() function

When I open the Python shell and import from dd_game import get_moves I get an IndentationError on the build_cells() function. This doesn't much sense to me as the indentation seems to be correct.

code:

def build_cells(width, height):
    """Create and return a width x height grid of two tuples

    >>> cells = build_cells(2, 2)
    >>> len(cells)
    True

    """

    cells = []

    for y in range(height):
        for x in range(width):
            cells.append((x, y))
    return cells

The error occurs on for y in range(height):

Traceback (most recent call last):

I copy/pasted your code into my editor and it worked fine. Hopefully you figured it out!

I used to get indentation errors a lot when using workspaces. I switched over to a different editor (Visual Studio Code) and found that having indentation lines shown really helped me catch/fix these errors with much less frustration. Maybe give it a try?
