Question

I’m starting to work on problems for google’s Code Jam. However I there seams to be a problem with my submission. Whenever I submit I am told “Your output should start with ‘Case #1: ‘”. My output a print statement starts with “”Case #%s: %s”%(y + 1, p)” which says Case #1: ext… when I run my code.

I looked into it and it said “Your output should start with ‘Case #1: ‘: If you get this message, make sure you did not upload the source file in place of the output file, and that you’re outputting case numbers properly. The first line of the output file should always start with “Case #1:”, followed by a space or the end of the line.”

So what is an output file and how would I incorporate it into my code?

Extra info: This is my code I’m saving it as GoogleCode1.py and submitting that file. I wrote it in the IDLE.

import string
firstimput = raw_input ("cases ")
for y in range(int(first)):
    nextimput = raw_input ("imput ")
    firstlist = string.split(nextimput)
    firstlist.reverse()
    p = ""
    for x in range(len(firstlist)):
        p = p +firstlist[x] + " "
    p = p [:-1]
    print "Case #%s: %s"%(y + 1, p)

I/O redirection aside, the other way to do this would be to read from and write to various files. Lookup file handling in python

input_file = open('/path/to/input_file')
output_file = open('/path/to/output_file', 'w')
for line in input_file:
    answer = myFunction(line)
    output_file.write("Case #x: "+str(answer))
input_file.close()
output_file.close()
