It's always helpful to give example input and output, as well as show us
what you've done so far.It's *also* a good idea to tell us what your end
goal is, rather than just "I have this data and I want to manipulate it
thus", because oft times it turns out that there are much better ways to
accomplish the end goal.
Here's what it sounds like you say you want to do:
line_xy = ['1 1', '2 2', '3 3', '4 4'] # Coordinates along the line y = x
def dictify_list(coords):
returnval = {}
for pair in coords:
x, y = pair.split()
returnval[x] = y
return returnval
dictify_list(line_xy) # produces {'1':'1', '3':'3', '2':'2', '4':'4'} or
some equivalent dict - they're non-ordered
But I can't think of a time that I would want data collected this way. My
guess is that unless you have a super special case, you don't really need
the data that way either.
