KeyError in Python Morse-Code-Übersetzer

Question

Ich schreibe einen Morsecode zu Text/Text zu Morse-Code-Programm in Python 3, und es scheint gut zu funktionieren, bis ich einen Buchstaben gebe, dann bekomme ich die folgende Fehlermeldung:

Traceback (most recent call last): 
    File "X:\GCU\CST-110\Week 5 Projects\Python Projects\Chapter 9 Exercise 21.py", line 79, in <module> 
    print(words_to_morse(morse_dict)) 
    File "X:\GCU\CST-110\Week 5 Projects\Python Projects\Chapter 9 Exercise 21.py", line 45, in words_to_morse 
    print(morse_dict[ch],end="") 
KeyError: 'J' 

Wo fehlt mir das Problem? Code ist unten. Danke für die Hilfe.

        print("/",end="\n")

    print("")

    morse_str=morse_str.replace("/",".-.-..-.-.") 
    morse_list=morse_str.split() 
    words_list=[]

     continue

1) process_line() kehrt nicht morse_dict richtig war es eine lokale Variable, kehren sie zur Schleife der Außenseite und auch

2) die unten Stück nicht als Schlüsselspeicher Charakter, sie speichert Wort als Schlüssel

for line in fileObj: 
    line.strip() 
    line=line.split()
