I've finally finished all the code for my project. Now I need all of the things that are labelled "print" to actually be exported into a .txt document. How would I go about doing that?
我终于完成了我项目的所有代码。现在我需要将所有标记为“打印”的内容实际导出到 .txt 文档中。我该怎么做？

I would not even approach this from a python-fix perspective, but simply redirect the output of running your python script:
我什至不会从 python-fix 的角度来解决这个问题，而是简单地重定向运行 python 脚本的输出：
python /path/to/script/myscript.py > /path/to/output/myfile.txt
Nothing has to change in your script, and all print statements will end up in your text file.
您的脚本中没有任何更改，所有打印语句都将在您的文本文件中结束。

Redirect stdoutto a file.
重定向stdout到一个文件。
import sys
sys.stdout = open('log.txt', 'w')
print 'Write this to file.'
EDIT: if you are using this method, still close the file when you are done writing: sys.stdout.close()
编辑：如果您正在使用此方法，请在完成写入后仍关闭文件： sys.stdout.close()

1) open a file for writing:
1）打开一个文件进行写入：
f = open("file.txt", "w")
2) replace all your print statements by print >>f, for example:
2）用print >>f替换所有打印语句，例如：
print "hello"becomes print >>f, "hello
print "hello"变成 print >>f, "hello
3) close the file when you're done
3）完成后关闭文件
f.close()
