Trying to print an uneven list to a even table

[perfringo]

if I wanted to do this with out adding commas or removing the spaces is this possible?

I think that this assignment more about cleaning string than printing table. As there are strings which don't have spaces between state abbreviation and zip-code one should normalise them (split to chars and construct new string without spaces) and use index (all states have two-letter abbreviation):

for row in mycities: 
    city, state_and_zip = row.split(',') 
    location = ''.join(char for char in state_and_zip.split()) 
    print(f'{city:20}{location[:2]:3}{location[2:]:10}') 

Output:
Cape Girardeau      MO 63780     
Columbia            MO 65201     
Kansas City         MO 64108
