Hello,
I am new to Python and have one simple question to which I cannot find
a satisfactory solution.
I want to read text line-by-line from a text file, but want to ignore
only the first line. I know how to do it in Java (Java has been my
primary language for the last couple of years) and following is what I
have in Python, but I don't like it and want to learn the better way
of doing it.
file = open(fileName, 'r')
lineNumber = 0
for line in file:
if lineNumber == 0:
lineNumber = lineNumber + 1
else:
lineNumber = lineNumber + 1
print line
Can anyone show me the better of doing this kind of task?
Thanks in advance.

Files are iterators, and iterators can only go through the object once. Just
call next() before going in the for loop. Also, don't use "file" as a
variable name. It covers up the built-in type.
afile = open(file_name, 'r')
afile.next() #just reads the first line and doesn't do anything with it
for line in afile :
print line

==================
actually:
import os
file = open(filename, 'r')
for line in file:
dummy=line
for line in file:
print line
is cleaner and faster.
If you need line numbers, pre-parse things, whatever, add where needed.
