Hers is my code challenge and my code. I'm stuck, not sure why its not working properly
-write a function named plaintext that takes a single parameter of a string encoded in this format: before each character of the message, add a digit and a series of other characters. the digit should correspond to the number of characters that will precede the message's actual, meaningful character. it should return the decoded word in string form
""" my pseudocode:
#convert string to a list
#parse string where the element and the index plus one returns the desired index
#return decoded message of desired indexes """
encoded_message = "0h2ake1zy"
#encoded_message = "0u2zyi2467"
#encoded_message = raw_input("enter encoded message:")
for index, character in enumerate(list(encoded_message)):
character = int(character)
decoded_msg = index + character + 1
Here are some hints.
First decide what looping construct you want to use. Python offers choices: iterate over individual characters, loop over the indices of the characters, while loop. You certainly don't want both a while and a for loop.
You're going to be processing the string in groups, "0h", then "2ake", then "1zy" to take your first example string. What is the condition that will cause you to exit the loop?
Now, look at your line
decoded_msg = index + character + 1. To construct the decoded string, you want to index into the string itself, based on the digit's value. So, this line should contain something like,
encoded_message[x] for some x, that you have to figure out using the digit.
Also, you'll want to accumulate characters as you go along. So you'll need to begin the loop with an empty result string
decoded_msg="" and add a character to it
decoded_msg += ... for each iteration of the loop.
I hope this helps a little more than just giving the answer.
