new = ['|<', '@', '1', '3', '7', '0', '8', '\/']
old = ['K', 'A', 'L', 'E', 'T', 'O', 'B', 'V']
ask_user = input("Type a phrase: ")
def ask_replace_letters():
ask_user = input("Do you want to replace the letters? ").upper()
if ask_user == "YES":
ask_user1 = input("What letters would you like to replace? ").upper()
for letter in ask_user1:
if letter not in old:
print("The program cannot replace the following letter(s): ", letter)
print(replace_letters())
elif ask_user == "NO":
print(replace_phrases())
else:
print("Please enter yes or no.")
def replace_letters():
result = ask_user
for i in range(len(old)):
result = result.replace(old[i], new[i])
return result
ask_replace_letters()
Upon running the code, I receive:
Type a phrase: BYE
Would you like to replace letters? yes
Which letters do you wish to replace? BYW
This program is unable to replace the letter(s): Y
8Y3
This program is unable to replace the letter(s): W
8Y3
The desired output is as follows:
Type a phrase: BYE
Would you like to replace letters? YES
Which letters do you want to replace? BYW
This program cannot replace the following letter(s): YW
8YE
Is there a solution to this issue? Essentially, I would like the function to receive the user's input, verify if it's in the list, substitute it, and indicate any that couldn't be modified. I apologize for my limited Python knowledge.
