  - - - d = {'simple_key':'hello'}
        grab hello
        d['simple_key']
      - d = {'k1':{'k2':'hello'}}
        grab hello
        d['k1']['k2']

        r = read only
        w = write only
        a = append (adding more text at the end of a file)
        r+ = reading and writing
        w+= writing and reading (overwrite existing file)
