Question

到目前为止，我还没有找到任何有助于在网上解释这一点的内容，我认为这一定是我的一些问题。问题是，在Python 3.4中使用Spyder2作为IDE我在列表中不断出现语法错误，我需要帮助理解它。

所以这就是我的尝试。

使用'/'表示多行声明。
仔细检查错误的空白区域。
保持列表的长度小于该行。

当我保持列表相对较小时，它似乎工作正常，但一旦超过76个字符就开始给我这个错误：

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

代码

# -*- coding: utf-8 -*-
"""
Spyder Editor

This is a temporary script file.
"""
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)

Answer 1

这是不正确的语法。对于[]，您有list，但是您要将每个值分配给另一个值，这更像是dict，因此不起作用。您可以通过将其发送到dict()函数来创建字典来解决最小的更改：

>>> 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']
