How to write characters to a file?

Question

Python

Hello, I'm trying to make it so that after pressing a key it is immediately written to a text file
. I tried this:
import keyboard

x = open('test.txt','a')
def print_pressed_keys(e):
x.write(str( e.name))
print(e.name)

keyboard.hook(print_pressed_keys)
keyboard.wait()
The file remains empty, but the press passes and print prints it out. Tell me what to do.

Answer 1

Because the file didn't close -> didn't save.

def print_pressed_keys(e):
    with open('test.txt', 'a') as f:
        f.write(str(e.name))
    print(e.name)
