f.close()

控制台:

为什么不显示文件内容?

Why is it not displaying the contents of the file?

谢谢，

推荐答案

你不是在显示文件的内容，只是在阅读它.

You are not displaying the contents of the file, just reading it.

例如，您可以执行以下操作:

For instance you could do something like this:

with open('aaa.txt') as infp:
    data = infp.read()

print data # display data read 

使用 with 也会自动关闭文件

Using with will also close the file for your automatically
