py.exe: printing ascii number 7

[DeaD_EyE]

You should look at this table: http://www.asciitable.com/
0x7 is BEL.

To see what's possible with ascii, you can test this tiny program:

import time
from urllib.request import urlopen


def get():
    baseurl = 'https://vt100.net/animation'
    files = [f'{baseurl}/xmas{n}.txt' for n in range(10)]
    for file in files:
        yield urlopen(file)


def draw():
    for animation in get():
        for char in animation:
            print(char.decode(errors='ignore'), end='', flush=True)
            time.sleep(0.05)


if __name__ == '__main__':
    draw()
