Sorry Emile, The OP is correct.
######################
>>> help(''.endswith)
endswith(...) method of builtins.str instance
S.endswith(suffix[, start[, end]]) -> bool
Return True if S ends with the specified suffix, False otherwise.
With optional start, test S beginning at that position.
With optional end, stop comparing S at that position.
suffix can also be a tuple of strings to try.
#######################
The tuple is the set of suffices and the numbers are the
start/end points. Its not often seen like that but the
OP is quite correct.
The test against False is unusual it woyuld normally look like
if not cell.endswith(suffix, 14, 16):
but that is just a style issue.
