There is a file there called data.csv. The python script indicates an error: Error in Python IOError: [Errno 2] No such file or directory: 'data.csv' What does this error mean and how do I fix it?

You can fix the problem by either cding to the directory containing data.csv before executing the script, or by using the full path to data.csv in your script, or by calling os.chdir(...) to change the current working directory from within your script. Note that all subsequent commands that use the current working directory (e.g. open and os.listdir) may be affected by this. share|improve this answer edited Oct 21 '12 at 18:09 answered Oct 21 '12 at 17:49 unutbu 385k46713826 2 os.chdir() should be used with care or better yet not at all in this case (os.path.join could be used instead). –J.F.
