Python制表未正确写入文本文件

Question

我试图将一个简单的列表制成一个使用tabulate() 格式化的文本文件，fancy_grid 格式是我想要的，它在控制台中打印正常，但是在写入文本文件时，我收到以下错误。删除参数tablefmt='fancy_grid' 使其编写一个简单的表，但这不是我想要的。我也尝试过使用 docx 格式，但仍然出现同样的错误

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

我在linux下运行它。它有效。

我认为问题不在于tabulate，而在于写入文件

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")
