Python 制表未正确写入文本文件

Question

我正在尝试将一个简单列表制成一个使用 tabulate() 格式化的文本文件，fancy_grid 格式是我想要的并且它在控制台中打印正常，但是在写入文本文件时，我得到下面的错误。删除参数 tablefmt='fancy_grid' 使其编写一个简单的 table，但这不是我想要的。我也尝试过使用 docx 格式，但仍然出现相同的错误

这是在 Windows 环境中。

代码

from tabulate import tabulate

l = [['{:<118}.'.format("Hassan"), 21, "LUMS"], ["Ali", 22, "FAST"], ["Ahmed", 23, "UET"]]
table = tabulate(l, headers=['Name', 'Age', 'University'], tablefmt='fancy_grid', showindex="always")

with open("C:\Users\John\Desktop\kaita.txt", "w") as outf:
    outf.write(table)
os.startfile("C:\Users\John\Desktop\kaita.txt", "print")

错误

Traceback (most recent call last):
  File "E:/Developement/Desktop Applications/GuiWithWx/Learn/Teach/runpython.py", line 160, in <module>
    outf.write(table)
  File "C:\Python\lib\encodings\cp1252.py", line 19, in encode
    return codecs.charmap_encode(input,self.errors,encoding_table)[0]
UnicodeEncodeError: 'charmap' codec can't encode characters in position 0-150: character maps to <undefined>

Answer 1

请添加：.encode("utf-8").

from tabulate import tabulate

l = [['{:<118}.'.format("Hassan"), 21, "LUMS"], ["Ali", 22, "FAST"], ["Ahmed", 23, "UET"]]
table = tabulate(l, headers=['Name', 'Age', 'University'], tablefmt='fancy_grid', showindex="always")

with open("C:\Users\John\Desktop\kaita.txt", "w") as outf:
    outf.write(table.encode("utf-8"))
os.startfile("C:\Users\John\Desktop\kaita.txt", "print")

信用：UnicodeEncodeError: 'charmap' codec can't encode characters

Answer 2

我运行它在linux下。它有效。

我认为问题不在tabulate，而是在写入文件

您可以尝试使用 utf-8 文件格式保存文件：

import io
from tabulate import tabulate

l = [['{:<118}.'.format("Hassan"), 21, "LUMS"], ["Ali", 22, "FAST"], ["Ahmed", 23, "UET"]]
table = tabulate(l, headers=['Name', 'Age', 'University'], tablefmt='fancy_grid', showindex="always")

with io.open("C:\Users\John\Desktop\kaita.txt", "w", encoding="utf-8") as outf:
    outf.write(table)

os.startfile("C:\Users\John\Desktop\kaita.txt", "print")
