[Tutor] String question (original) (raw)

For starters, you don't need to import string. string.split(line) can be done with line.split(). line is of type str, which is a built in and contains most of the string members. import string is only necessary rarely.

Secondly I could be wrong, but I don't think you have given enough code to really fix the problem. Your error says it's on line 0, but your input() in what you pasted is definitely not. My guess is you have indented someplace you shouldn't, or vice versa, or you have missed a " or something like that.

Good luck

Hello,

I have posted in here a few times asking questions about data filtering. I have part of a code set-up for removing header information and then extracting a column of data (thanks to the python list for help and book recommendations) then writing the column to another file. My question is twofold: How do I maintain a columned format when I write the data to a new file? When I place the data extracting part of my program into the big filter program I receive the error (I am guessing I have an indent problem or syntax): Traceback (most recent call last): File "C:\Python23\filter.py", line 49, in ? input () File "", line 0 ^ SyntaxError: unexpected EOF while parsing. I have included both the extracting code and the filter code I am trying to place the extracting code in. Thank you very much.
