####### YOUR CODE HERE ######

#You will need to find the password that matches the website

#You will then need to decrypt the password

#

#$1.$ Create a loop that goes through each item in the password list

# You can consult the reading on lists in Week $5$ for ways to loop through a list

#

#$2.$ Check if the name is found. To index a list of lists you use $2$ square backet sets

# So passwords$[0][1]$ would mean for the first item in the list get it's $2$nd item $($remember$,$ lists start at $0)$

# So this would be 'XqffoZeo' in the password list given what is predefined at the top of the page.

# If you created a loop using the syntax described in step $1,$ then i is your 'iterator' in the list so you

# will want to use i in your first set of brackets.

#

#$3.$ If the name is found then decrypt it$.$ Decrypting is that exact reverse operation from encrypting. Take a look at the

# caesar cypher lecture as a reference. You do not need to write your own decryption function, you can reuse passwordEncrypt

#

# Write the above one step at a time. By this I mean, write step $1...$ but in your loop print out every item in the list

# for testing purposes. Then write step $2,$ and print out the password but not decrypted. Then write step $3.$ This way

# you can test easily along the way.
