Increase value in hash table

[moonhk]

Works.

     prndev = line.split()
         # print line
         for key in prndev :
             if key in 'lpr':
                val = prndev[5].replace("-P","")
                if val not in printque:
                   printque[val] = 1
                else:
                   printque[val] = printque[val] + 1
             if key in "/dev/null":
                 val='null'
                 if val not in printque:
                    printque[val] = 1
                 else:
                    printque[val] = printque[val] + 1
