如何使python同时加密大写和小写?

如何使python同时加密大写和小写?,python,python-3.x,case-sensitive,encryption,Python,Python 3.x,Case Sensitive,Encryption,基本上,我希望密码短语作为输出,大写字母被密码转换为大写字母,小写字母被密码转换为小写字母,但没有任何空格或符号被密码转换。它可以加密由所有大写字母组成的段落和由所有小写字母组成的段落,但不能混合使用这两种字母。这是我的 def encrypt(phrase,move): encription=[] for character in phrase: a = ord(character) if a>64 and a<123: if a!=(91,96):

对于短语中的字符:
a=ord(字符)
如果a>64且a
然后

你想在这里发生什么?应该用小写字母代替小写字母,反之亦然吗?基本上是的,我会去编辑这个问题你的最终目标是什么?你想加密还是编码?@miraclixx我不知道加密和编码的区别,但我希望它能像凯撒密码一样工作。你想在这里发生什么?应该用小写字母代替小写字母,反之亦然吗?基本上是的,我会去编辑这个问题你的最终目标是什么?你想加密还是编码?@miraculixx我不知道加密和编码之间的区别,但我确实想让它像凯撒密码一样工作。使用它,不断得到这个

hmmm他们可能在python 3中已经删除了它。请给我一分钟时间,弄清楚他们将它改成了什么样子,就像在python3中一样。你可以使用
