8.6 HOMEWORK Challenges (Google Colab) 

COPY COLAB & SUBMIT Through the form Below

Challenge #1: ASCII Practice problem

There is a secret passcode encoded by a series of given numbers (that correspond to the hidden password using the ASCII table) in a list! Your job is to cycle through the list and decode the password using the ASCII table, then print the password that you've decoded!

Challenge #2: The caesar shift - decrypt

If we are given a text file written in English and encrypted by a Caesar Shift, can we figure out what shift value was used?

• We could use “brute force” and try every possible value to see what shift produces legible prose…

• We'd need to possibly try every shift value from +1 to +255. It would take a long time to sift through all the decrypted files!!

Go to your Colab Notebook and read the provided comments that will guide you through how to decrypt this message. This problem builds off of what we did with the encryption!

Challenge #3: dna palindrome

Parse and filter through the file given to determine which DNA sequences are palindromes. You should utilize the skeleton code given (you do not need to change this), and your Colab Notebook provides more details on what steps you need to take! An example of what your output should look like is below:

Challenge #4: Build Your Own

• This practice is very open ended and you are welcome to take it in any direction you would like!

• Your job is to encrypt and decrypt your favorite song, book excerpt, or any form of text of your choosing. The only rule is that you cannot use the same encryption we did in the previous example.

• After you encrypt your message, send it to a friend and see if they can decrypt it!
