A demonstration of writing prettier arrays in Python.

list.py

major_lst = []
symbols = ['.',',','!','@','#','$','%','&','*','^','-',
           '|','[',']','{','}','(',')','_','+','=',';',
           ':',"'",'"','?','/','>','<','`','~','\\']
uppercase = ['A','B','C','D','E','F','G','H','I','J','K',
             'L','M','N','O','P','Q','R','S','T','U','V',
             'W','X','Y','Z']
lowercase = ['a','b','c','d','e','f','g','h','i','j','k',
             'l','m','n','o','p','q','r','s','t','u','v',
             'w','x','y','z',' ']
numbers = [0,1,2,3,4,5,6,7,8,9]

pri_list = symbols + uppercase + lowercase + numbers

thanks a lot
