Python：如何导入带有控制字符分隔符的 csv 类 dat 文件

Question

我有一个以 DC4 控制字符作为分隔符的数据文件。这是我现在的代码（我从别人那里复制的，不是我的代码）。

import csv
with open('Test.dat') as csv_file:
    csv_reader = csv.reader(csv_file, quotechar='þ', delimiter='')
    line_count = 0
    for row in csv_reader:
        if line_count == 0:
            print(f'Column names are {", ".join(row)}')
            line_count += 1
        else:
            print(f'\t{row[0]} works in the {row[1]} department, and was born in {row[2]}.')
            line_count += 1
    print(f'Processed {line_count} lines.')

如您所见，字符由一个框显示，到目前为止只有 notepad++ 可以读取它。我找到了 curses.ascii.isctrl(c)，它似乎能够通过 python 读取该字符，然后将其读取为插入符号？ (https://docs.python.org/3.2/library/curses.ascii.html)

我是编码新手，不确定如何实现它，或者它是否对我有用。下面是我试图以文本和屏幕截图形式读取的 dat 文件示例。

þIdentifierþþColumn 2þþColumn 3þ
þXX_0012345þþRandom Data 1þþRandom Data 1þ
þXX_0012346þþRandom Data 6þþRandom Data 2þ
þXX_0012347þþRandom Data 1þþRandom Data 3þ
þXX_0012348þþRandom Data 8þþRandom Data 4þ
þXX_0012349þþRandom Data 1þþRandom Data 5þ
þXX_0012345þþRandom Data 9þþRandom Data 1þ

Text File to see the DC4 control character

这是在 python 3.6.1 上使用此代码时的输出。一切看起来都不错，除了 þ 字符，这是 DC4 字符的读取方式。

Column names are þIdentifierþ, þColumn 2þ, þColumn 3þ
    þXX_0012345þ works in the þRandom Data 1þ department, and was born in þRandom Data 1þ.
    þXX_0012346þ works in the þRandom Data 6þ department, and was born in þRandom Data 2þ.
    þXX_0012347þ works in the þRandom Data 1þ department, and was born in þRandom Data 3þ.
    þXX_0012348þ works in the þRandom Data 8þ department, and was born in þRandom Data 4þ.
    þXX_0012349þ works in the þRandom Data 1þ department, and was born in þRandom Data 5þ.
    þXX_0012345þ works in the þRandom Data 9þ department, and was born in þRandom Data 1þ.

对此的任何帮助将不胜感激。谢谢！

Answer 1

您可以为此使用转义字符。 DC4 是 Ascii 20 (0x14)

csv_reader = csv.reader(csv_file, quotechar='þ', delimiter='\x14')

Answer 2

事实证明这是我的计算机而不是 python 的问题。显然我看不到那个字符，它只显示为一个白框。有没有办法编辑 windows 10 以显示该字符
