How to fix bugs in Morse alphabet code?

[dokipo]

Your function reads the data not into morse_text but into mroz_text. Probably a typo?

def decode(mroz_text: str) -> str:
    morse_array = morse_text.split("/")

Yes, and I also changed plaintext to plain_text but now i have there


Traceback (most recent call last):
File "C:/Users/dokipo/Desktop/pythonprojects/alphabet.py", line 29, in <module>
print(decode(encode("This is first testing sentence.")))
File "C:/Users/dokipo/Desktop/pythonprojects/alphabet.py", line 25, in <module>
plain_text += morse[current_element]
builtins.KeyError: 't'


What´s wrong with "t"?
