Empty the file contents or truncate file in python

I am opening a file called test.txt with the file object say file1. Without closing the previously opened file, I am opening same file test.txt with file object say file2 and trying to empty the file contents with file.truncate(0).

I can see my file contents are not getting deleted. Is there any way I can fix this?

import os
def _write(_file):
        _file.write("Hello World")

file1=open("test.txt",'a')

_write(file1)

file2=open("test.txt",'a')
file2.truncate(0)

I want delete the file contents without using same file object file1 because the the code which deletes the file contents is in different file.

You can use with in order to close file after the process done.

with open("test.txt",'a') as file1:
    _write(file1)

with open("test.txt",'a') as file2:
    file2.truncate(0)

One way to empty a file is opening it in writing mode. You can close it right after:

open('test.txt', 'w').close()
