Hi all,

In this task, i messed the timings of each character. I get certain first [Th1b4ud : ok] characters by each try. The problem is after this [Th1b4ud : ok] character. I get nonsense timings which are less than the first ones. I suppose there is a charset problem. Is there a hint ? Maybe French or Spanish...

Thx for getting around this one...  🙄

Well,

i tried all printable ones as usual and as i mentioned above i get exact [Th1b4ud : ok] characters with a constant amount of delay for each but after that, the distances are too close, so i can not differ the values for sure.

hmm.. someone there ?  🙂


Edit:
ok i got it. no problem...

The char you are looking for are in string.printables in Python. Check your script
