Line Endings in a Mixed Environment Application
If you have to operate on text strings and files in an application that can be used interchangeaby in Windows and other environments, it can be a bit confusing. Below is what I found (all on Python 3.4). When reading a file into a Python string: File contents Windows Others 'A' \x0D \x0A 'B' 'A\nB' (len=3) '\A\r\nB' (len=4) 'A' \x0A 'B' 'A\n\B' (len=3) '\A\nB' (len=3) When writing a Python string to a file, this is the file content: String Windows Others 'A\nB' 'A' \x0D \x0A 'B' 'A' \x0A 'B' 'A\r\nB' 'A' \x0D \x0D \x0A 'B' 'A' \x0D \x0A 'B' If you copy a file from a non-Windows to a Windows system, the file will not have CR, but the Python app in Windows will read nicely. But if you write it out again, then the new file will have different line endings from the original. If you copy a file from Windows to a non-Windows system...
