Anyone who got the previous message, there was a typo. This looks better
opt_map = {'m': 'Queue Manager', 's': 'Server', 'p': 'Port',
'o': 'Object', 'k': 'Key', 't': 'To',
'c': 'Check', 'd': 'Report', 'q': 'Display}
afile = open("filename")
settings = {}
for aline in afile:
splitline = aline.split()
flags, options = splitline[::2], splitline[1::2]
flags = [f[1] for f in flags] # get rid of pesky "-"s
for flag, option in zip(flags, options):
settings[opt_map(flag)] = option
print "%s = %s" % (opt_map(flag), option)
afile.close()
