多行数组或列表语法错误

Question

到目前为止，我在网络上还没有找到任何可以帮助解释这一问题的东西，我认为这一定对我有帮助。问题是，在使用Spyder2作为IDE的Python 3.4中，我一直在列表中遇到语法错误，我需要帮助来理解它。

所以这是我尝试过的。

• 在多行语句中使用“ /”。
• 仔细检查是否有空白。
• 使列表的长度小于行的长度。

当我将列表保持相对较小时，它似乎可以正常工作，但是一旦超过76个字符，就会出现此错误：

runfile('C:/Users/ghost/.spyder2-py3/temp.py', wdir='C:/Users/ghost/.spyder2-py3')
  File "C:/Users/ghost/.spyder2-py3/temp.py", line 7
    alphabet = [a = 0, b = 1, c = 3, d = 4, e = 5, f = 6, g = 7, h = 8,
SyntaxError: invalid syntax

码

# -*- coding: utf-8 -*-

alphabet = [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]
print(alphabet)

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']
