Question

在python中，我如何从包含以下内容的txt文档中选择单个字符：

A＃

M *

N％

（在单独的行上）...然后用字母作为键，符号作为值更新字典。

我最接近的是：

ftwo = open ("clues.txt", "r")
for lines in ftwo.readlines():
    for char in lines:

我对编码很新，所以不能解决它！

Answer 1

假设每行包含两个字符（首先是键，然后是值）：

with open('clues.txt', 'r') as f:
    myDict = {a[0]: a[1] for a in f}

如果输入文件中有空行，则可以将其过滤掉：

with open('clues.txt', 'r') as f:
    myDict = {a[0]: a[1] for a in f if a.strip()}

Answer 2

首先，您希望一次读取每一行：

my_dict = {}
with open ("clues.txt", "r") as ftwo:
    for line in ftwo:
        # Then, you'll want to put your elements in a dict
        my_dict[line[0]] = line[1]

将外部文件中的字符添加到字典中
