在 python 上读取文件返回一个空字符串

Question

I have been trying to read a file in python, the thing is that it returns an empty string. Here is the code:

with open('data.txt') as file:
    content = f.readlines()
    print(content) #prints nothing

note: It's a really big file, is that a problem?

Answer 1

1. change f.readlines() to file.readlines() This is only a typo. But I don't know why you don't get the error here. I think you open another file as f And You get the empty string here 'cause if you try to read a file more than once, you got an empty string except for the first time.
2. As you say the file size is 4TB , This could be the problem because of Max File Size In Python

Answer 2

with open('data.txt') as file:
    content = file.readlines()
    print(content) #prints nothing

This should work i think

Answer 3

您需要确保您的文本文件名是正确的，但最重要的是，您需要提供文件的完整路径，以防它与脚本不在同一目录中。
