Right now im using standard text file storage and max(), min() and sorted() for sorting and ordering.

Try using shelve instead.

Import shelve

#to write
writer = shelve.open('textfile.txt')
writer['textfile'] = 'textintextfile'
writer.close()

#to read
reader = shelve.open('textfile.txt')
text = reader['textfile']
reader.close()

Also shelve may be favorable since user's can't access the text file easily. Neither mac not windows have a built in reader for the type of text file it creates.

you can also use and call the following functions
def shelvewrite(textfilename,towrite): #write to text file
textfilenametxt = textfilename + '.txt'
writer = shelve.open(str(textfilenametxt))
writer[str(textfilename)] = towrite
writer.close()
def shelveread(textfilename): # read form text file
textfilenametxt = textfilename + '.txt'
reader = shelve.open(str(textfilenametxt))
text = reader[str(textfilename)]
reader.close()
return text
def shelveappend(textfilename, toappend): #append to text file
textfilenametxt = textfilename + '.txt'
read = shelveread(textfilename)
toappend = (read, toappend)
shelvewrite(textfilename, toappend)
