這篇文章一看就是將所有字串反轉且字串中單詞也反轉了所以要還原成正常順序就要進行反轉

def gettext():
    txt=open("input.txt","r",encoding='UTF-8').read()
    txt=txt.lower()
    for ch in '!"#$%&()*+,-./:;<=>?@[\\]^_`{|}，~ ‘’':
        txt=txt.replace(ch," ")
    return txt
rtxt=gettext()
str_dst=rtxt.split()#以空格符為分隔符，將各單詞取出來放在串列中
result = ""
for c in str_dst:#拆字
    new=c[::-1]#將字串中的單詞反轉
    result =new+result#將字串反轉
    print(result)

反轉后的內容為
