# # 代码中的类名、方法名、参数名已经指定,请勿修改,直接返回方法规定的值即可 # # # @param s string字符串 # @param n int整型 # @return string字符串 # class Solution: def trans(self , s: str, n: int) -> str: # write code here all= s.split(' ') all = all[::-1] result = '' for item in all: item= item.swapcase() result = result + item+' ' print(result) return result[:-1]
item.swapcase()这函数很重要
