Question

I have a python dictionary, definition of which does not fit in a single line. Could anyone please tell me guidelines for python dictionaries. I currently have this which does not look good to my eyes.

initialstate =  {
                    'state':grid,
                    'f':find_manhattan_distance(grid,goal),
                    'g':0,
                    'h':find_manhattan_distance(grid,goal),
                    'ancestor': None
                }

Answer 1

pep8.py says:

mydict.py:2:28: E231 missing whitespace after ':'
mydict.py:1:15: E222 multiple spaces after operator

Try this:

initialstate = {
    'state': grid,
    'f': find_manhatten_distance(grid, goal),
    'g': 0,
    'h': find_manhatten_distance(grid, goal),
    'ancestor': None
}

Notice the change in spacing after commas and operators. This version passes all the pep8.py tests.
