The Changelog constructor takes the changelog contents as an iterable of
str or unicode lines (e.g. a file object), or a single str or unicode.
It doesn't take a filename. You want something like
>>> from debian import changelog
>>> f = open('/tmp/python-debian-test.changelog')
>>> c = changelog.Changelog(f)
>>> c.get_version()
Version('0.1')
It seems pretty clear in the docs:
>>> help(changelog.Changelog)
Help on class Changelog in module debian.changelog:
class Changelog(__builtin__.object)
| Represents a debian/changelog file.
|
| Methods defined here:
|
| __init__(self, file=None, max_blocks=None, allow_empty_author=False,
strict=True, encoding='utf-8')
| Initializer.
|
| Args:
| file: The contents of the changelog, either as a str, unicode
object,
| or an iterator of lines (each of which is either a str or
unicode)
Unfortunately, you have to get at them with an interactive interpreter
or by examining the source. We probably should be putting epydoc output
in /usr/share/doc/python-debian.
