多行数组或列表语法错误

那是不正确的语法。您有[]一个list，但您要将每个值分配给另一个值，该值更像是dict，因此不起作用。您可以通过将其发送给dict()函数以创建字典，以最小的更改来解决此问题：

>>> alphabet = dict(a = 0, b = 1, c = 3, d = 4, e = 5, f = 6, g = 7, h = 8,
...             i = 9, j = 10, k = 11, l = 12, m = 13, n = 14, o = 15, p = 16,
...             q = 17, r = 18, s = 19, t = 20, u = 21, v = 22, w = 23, y = 24,
...             x = 25, z = 26)
>>> alphabet['b']
