I’m stuck in here and have no idea how to go with this assignment. I’ve tried several things but it doesn’t work. Need some help. Here’s my screenshoot:
Hello Fish,
How many parameters does your decrypt function have?
And how many does your decrypt function call on the bottom have?
Close, but if you look at the line (above all of this) where you declare the vigenere function. It takes 3 parameters, which currently are: (message, key, direction=1). The direction is what is important. If we call the vingenere function with only 2 arguements, that means direction will automatically be set to 1. Which is fine for encryption, but for decryption we want it to go into the other direction. To achieve this we made the decrypt function where we automatically add in -1 when we call vingenere so that now we only need to call decrypt with the encrypted message and custom key.
But right now you removed the -1 from decrypt as well. So if you use decrypt now, it will call vigenere as if it’s trying to encrypt instead of dycrypt.
Anyway, long story short. You don’t need the -1 in your decrypt call at the bottom, but you definitely still need it in the vingenere call but only in the decrypt function.
Please post your code instead of a screenshot. Thanks
def encrypt(message, key):
return vigenere(message, key)
def decrypt(message, key):
return vigenere(message, key, -1)
encryption = encrypt(text, custom_key)
print(encryption)
decryption = decrypt(encryption, custom_key)
print(decryption)
This passes for me, you might wanna reset the step, or reload the browser and try to submit it again.
Yes HungryBee, it was the browser. I’m on the next. Thanks!
