Daily programmer challenge #102 was to create a program that counted the number of unique characters in a list of words and output the total number that were below a number you give it. My version does that and works like a command line program by passing system arguments. The file it takes should be a text file that can have multiple words on a line.
./102_intermediate.py file.txt 4
Total words with unique characters under or equal to 4 is 10442
