Recall the 2004 Harvard–Yale prank, in which the “Harvard Pep Squad” (i.e., Yale) tricked Harvard fans into spelling “GO HARVARD” with red placards, held above their heads like a bitmap:

Let’s simplify the prank a bit. Included in squad/ are six .txt files, each of which contains a “bitmap” that’s 6 “pixels” tall and 6 “pixels” wide, wherein each “pixel” is implemented as a hash (#) or a space ( ). Assume that each hash represents a red placard and that each space represents a white placard.

1. (4 points.) Let’s determine how many red placards Yale should bring to Harvard for a given bitmap. In squad/red.py, write a program that prints the number of hashes therein. The program should accept as its sole command-line argument the name of a .txt file. For instance, executing

 python red.py G.txt


in squad/ should print the number of hashes in G.txt. If the program is executed without a command-line argument or more than one command-line argument, it should exit with a status code of 1.

1. (6 points.) Let’s give Harvard fans something to spell. In squad/prank.py, implement a program that prints, from left to right, the contents of its command-line arguments, with one column of spaces between each letter. No need for additional spaces between words. For instance, executing

 python prank.py G.txt O.txt H.txt AR.txt VA.txt RD.txt


in squad/ should presumably print:

  ####   ####  #    #   ##   #####  #    #   ##   #####  #####
#    # #    # #    #  #  #  #    # #    #  #  #  #    # #    #
#      #    # ###### #    # #    # #    # #    # #    # #    #
#  ### #    # #    # ###### #####  #    # ###### #####  #    #
#    # #    # #    # #    # #   #   #  #  #    # #   #  #    #
####   ####  #    # #    # #    #   ##   #    # #    # #####


Well, ideally.
