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'
