unrelated: do not use the same name for different purposes in the same context. Use text = file.read() instead. Keep the text as Unicode, do not encode it to bytes unless it is absolutely necessary. –

I want to read a .csv file in python. I don't know if the file exists. My current solution is below. It feels sloppy to me because the two separate exception tests are awkwardly juxtaposed. Is th...

That way, you can simply cd to the directory containing your Python script file and run it. In any case, if your Python script file and your data input file are not in the same directory, you always have to specify either a relative path between them or …

If you're getting a FileNotFound error, the problem is most likely that the file name or the path to the file is incorrect. If you're trying to read AND write to a file that doesn't exist yet, change the mode from 'r' to 'w+'. It may also help to write out the full path before the file, for Unix users as: '/Users/paths/file'

This will cast a pretty wide net, and you can't assume that the exception is "file not found" without inspecting e.errno, but it may cover your use case. PEP 3151 discusses the rationale for the change in detail.
