Python: How do I clear a .txt file with the open() function?

Question

I have a simple program which opens a file and replaces text. However, I want the program to clear the file, then save what needs to be saved.
How do I do that? Or is there a simpler way to do so?
Thanks for your help :3

Answer 1

If you open the file with mode w it will overwrite the file if it already exists:

with open('your_file', 'w') as f:
    f.write('Some text\n')

This would create a file named your_file and write to it. If the file already exists, and you have permission to do so, it will overwrite the existing file.

You might also notice that I used open() within a with statement (context manager). This ensures that the file will be properly closed when execution leaves the scope of the context manager.

Answer 2

When you open a file in 'w' mode, it's content would be erased.

from doc - 'w' for only writing (an existing file with the same name will be erased)

Just open file as

open(file, 'w')

Answer 3

when opening in write mode, you clear the text in the file.

with open() as f:
    f.write("")

that'll fix it for you!
