Getting what the grading system gave me.

gistfile1.py

import sys

lines = []

for i in range(1, len(sys.argv)):
    lines.append("================================== START OF sys.argv%s==========================\n" % i)
    with open(sys.argv[i]) as fobj:
        for line in fobj:
            lines.append(line.decode('utf-8'))
    lines.append("================================== END OF sys.argv%s==========================\n" % i)        

s = "".join(lines)
raise ValueError(s)
