A file object is its own iterator so you can
do more simply:
input_file = open(filename)
input_file.next() # Skip line.
for line in input_file:
print line,
input_file.close()
Since the line read includes the terminating
EOL character(s), print it with a "print ... ,"
to avoid adding an additional EOL.
If the OP needs line numbers elsewhere in the
code something like the following would work.
infile = open(fileName, 'r')
for lineNumber, line in enumerate (infile):
# enumerate returns numbers starting with 0.
if lineNumber == 0: continue
print line,
