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.

#案例
#判断字符串是否以指定后缀结尾
str=‘xiaodeng love python‘
suffix=‘python‘
print str.endswith(suffix)#True
suffix=‘is‘
print str.endswith(suffix)#False
suffix=‘love‘
print str.endswith(suffix,4,13)#True
