[python]用数字1-10写数据文件 [英] [python]Writing a data file using numbers 1-10

问题描述

dataFile = open("temp1", "w")
for line in range(11):
    dataFile.write(line)
dataFile.close()

这是我目前所拥有的，但是当我运行此代码时，我不断收到错误消息.

This is what i have so far, but i keep getting a error when i run this code.

Traceback (most recent call last):
      File "datafile print liines.py", line 3, in <module>
        dataFile.write(line)
    TypeError: expected a character buffer object
    >Exit code: 1 

我希望这段代码使用数字 1-10 编写数据文件，所以我想使用 for 循环和范围可以做到这一点，但我不确定如何将它写入文件中每行一个数字.

I would like this code to write a dataFile using the number 1-10, so i was thinking using a for loop and range would do this, but im not sure how to write it to a file one number per line.

我知道 python 有一个 'w' 命令可以创建一个打开文件.

I know python has a 'w' command that creates a opens a file.

谁能给我一些建议，告诉我为什么我会收到这个错误以及我如何将它写入数据文件?

Can anyone give me some suggestion on why im getting this error and how i can write this to a datafile?

推荐答案

您必须向文件中写入字符串而不是整数.

You have to write a string to the file not an integer.

range(11) 返回整数列表:

In [1]: range(11)
Out[1]: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

尝试将第 3 行更改为以下内容:

Try changing line 3 to the following:

dataFile.write(str(line))

您可以添加换行符，以便文件中的结果文本看起来更具可读性:

You can add a newline so that the resulting text in the file appears more readable:

dataFile.write('%s\n' % line))
