print(caser(s))`运行后得到i hope you didnt translate it by hand thats what computers are for doing it in by hand is inefficient and that s why this text is so long using string maketrans is recommended now apply on the url
可知url为map.html。
输入map运行，得到ocr。
使用maketrans（）

inword = 'abcdefghijklmnopqrstuvwxyz'
