我正在使用Python 3.4。我在女巫一个节目，我有两个文件：Python不会创建新文件
problems = open("out/problems.tex", 'w')
answers = open("out/answers.tex", 'w')
如果我运行此我得到一个错误：
Traceback (most recent call last):
File "<encoding error>", line 10, in <module>
File "C:\Python33\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 247-251: character maps to <undefined>
如果我运行此：
problems = open("out/problems.tex", 'w', encoding='utf8')
answers = open("out/answers.tex", 'w', encoding='utf8')
我没有得到任何错误但我也没有得到任何文件'problems.tex'和'answers.tex'。有人知道我做错了什么吗？
这里是我的全部程序：
from polygen import *
head_file = open("tex/head.tex", 'r', encoding="utf8")
ground_file = open("tex/ground.tex", 'r', encoding="utf8")
problems = open("out/problems.tex", 'w', encoding="utf8")
answers = open("out/answers.tex", 'w', encoding="utf8")
head = head_file.read()
problems.write(head)
answers.write(head)
t = polymult(7, 1, 2, 2, 3, 4)
problems.write(t[0])
answers.write(t[1])
ground = ground_file.read()
problems.write(ground)
answers.write(ground)
problems.close()
answers.close()
是否该文件夹“出/”存在吗？你在写第一种情况的文件时是怎么写的？ –
是的，文件夹'out /'存在。我正在将LaTeX代码写入文件。 –
如果我'mkdir out'，然后在python 3 shell中执行'>>> problems = open（“out/problems.tex”，“w”，encoding =“utf8”）'，我得到一个零长度的文件。其余的代码是否在执行某些操作来删除文件？ –
