endswith(...)
S.endswith(suffix[, start[, end]]) -> bool
suffix:字符串或一个元素，就是需要查找的字符或字符串
start：字符串的开始位置
end：字符串结束位置

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.
