Is there a way to parse a config file like this with Python3?
path = .MyAppData
prefer = newer
path = Dokumente
Please don't blame me. ;) I didn't build the software producing config files like this. But they make sense in that special context.
I know ConfigParser and configobj for Python3 but don't see a way to do this.
The ConfigParser initialiser supports the strict=False argument, which allows duplicates. But which value is retained in that case isn't mentioned in the documentation as far as I can tell.
One simple solution is to convert the lines into a dictionary yourself;
In [1]: txt = '''path = .MyAppData
...: prefer = newer
...: path = Dokumente'''
In [2]: txt.splitlines()
Out[2]: ['path = .MyAppData', 'prefer = newer', 'path = Dokumente']
(After splitting the text in lines, you might want to filter out comments and empty lines.)
In [3]: [ln.split('=') for ln in txt.splitlines()]
Out[3]: [['path ', ' .MyAppData'], ['prefer ', ' newer'], ['path ', ' Dokumente']]
In [4]: vars = [ln.split('=') for ln in txt.splitlines()]
(At this point you might want to add a filter for the inner lists so that you only have lists of length 2, indicating a succesfull split.)
In [5]: {a.strip(): b.strip() for a, b in vars}
Out[5]: {'path': 'Dokumente', 'prefer': 'newer'}
In the dict comprehension (In [5]), later assignments will override earlier ones.
Of course, if prefer = older, you'd have to reverse the lines before the dict comprehension.
