我知道这样的帖子已经存在，但是我没有帮助。

我正在尝试制作一个加密模块，由于某种原因，Python决定开始向我抛出错误。我可以修复大多数问题，但我认为到目前为止我还不错。这是我的代码：

def encrypt(x):
    try:
        if x == str(x):
            x = str(x).split(['a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z'].join(None))
            x['a'] = 'q'
            x['b'] = 'w'
            x['c'] = 'e'
            x['d'] = 'r'
            x['e'] = 't'
            x['f'] = 'y'
            x['g'] = 'u'
            x['h'] = 'i'
            x['i'] = 'o'
            x['j'] = 'p'
            x['k'] = 'a'
            x['l'] = 's'
            x['m'] = 'd'
            x['n'] = 'f'
            x['o'] = 'g'
            x['p'] = 'h'
            x['q'] = 'j'
            x['r'] = 'k'
            x['s'] = 'l'
            x['t'] = 'z'
            x['u'] = 'x'
            x['v'] = 'c'
            x['w'] = 'v'
            x['x'] = 'b'
            x['y'] = 'n'
            x['z'] = 'm'
            return x
    except TypeError and Exception as e:
        raise TypeError('Cannot convert type to string.\nTech Notes: Original crash was: ' + str(e))
    except Exception as e:
        raise BaseException('Unknown failure of crash. Technical details below.\n' + str(e))
