如何在python 2.x和3.x中直接打印到文本文件? [英] how to print directly to a text file in both python 2.x and 3.x?

问题描述

除了使用write()之外，在Python 2和3中写入文本文件的另一种方式是什么?

Instead of using write(), what are the other way to write to a text file in Python 2 and 3?

file = open('filename.txt', 'w')
file.write('some text')

推荐答案

您可以使用print_function future import 以从python2中的python3获取print()行为:

from __future__ import print_function
with open('filename', 'w') as f:
    print('some text', file=f)

如果您不希望该函数在末尾添加换行符，请在print()调用中添加end=''关键字参数.

If you do not want that function to append a linebreak at the end, add the end='' keyword argument to the print() call.

但是，请考虑使用f.write('some text')，因为这更加清晰并且不需要__future__导入.

However, consider using f.write('some text') as this is much clearer and does not require a __future__ import.
