Python多文件编写问题 [英] Python Multiple file writing question

问题描述

我需要python写多个文件名，每个文件名都不同于最后一个。我把它写在for循环中。因此，从Python程序编写的数据文件应如下所示：data1.txt，data2.txt，data3.txt。我怎么能在Python 3.2中做到这一点？显然，这个数字是唯一改变的文件名。

I need python to write multiple file names, each file name is different than the last. I have it writing in a for loop. Therefore the data files written from the Python program should look like this: data1.txt, data2.txt, data3.txt. How can I do this in Python 3.2? Obviously, the number is the only thing changing as the file name.

推荐答案

或者使用和

for i in range(10):
    with open('data%i.txt' %i, 'w') as f:
        f.write('whatever')

with 负责在出现问题时关闭文件。如果您在for循环中创建文件，这可能尤为重要，

with takes care of closing the file if something goes wrong. This could be especially important if you are creating files in a for loop,
