String strip methods take a set of characters to strip, not a specific string / character sequence. They remove ALL the characters in that set from the left or right until the first character which is not in the set. This can be simply demonstrated here:
"foobar".strip("f") 'oobar' "foobar".strip("fo") 'bar'

Anyone experienced anything like this?
The behavior seems consistent but unexpected.
python 3.6 on both windows (10) and linux (ubuntu 18.04) seem to exhibit the same odd behavior.
something about a docker-image looking string seems to trigger this behavior. The behavior seems as expected for other strings.
