# 2. Write code that uses the string stored in org and creates an acronym which is assigned to the variable acro.
# Only the first letter of each word should be used, each letter in the acronym should be a capital letter, and there should be nothing to separate the letters of the acronym.

# For example, if org was assigned the string “hello to world” then the resulting acronym should be “HW”.

# 3. Write code that uses the string stored in sent and creates an acronym which is assigned to the variable acro.
# The first two letters of each word should be used, each letter in the acronym should be a capital letter, and each element of the acronym should be separated by a “. ” (dot and space).
# Words that should not be included in the acronym are stored in the list stopwords.
# For example, if sent was assigned the string “height and ewok wonder” then the resulting acronym should be “HE. EW. WO”.

# 4. A palindrome is a phrase that, if reversed, would read the exact same.
# Write code that checks if p_phrase is a palindrome by reversing it and then checking if the reversed version is equal to the original.
# Assign the reversed version of p_phrase to the variable r_phrase so that we can check your work.

# 5. Provided is a list of data about a store’s inventory where each item in the list represents the name of an item, how much is in stock, and how much it costs.
# Print out each item in the list with the same formatting, using the .format method (not string concatenation).
# For example, the first print statment should read The store has 12 shoes, each for 29.99 USD.

r_phrase = p_phrase[::-1]
can someone explain this part " :: " ?
Thank you!

The part #p_phrase[::-1] is a Python slice notation that reverses the order of the characters in the string variable p_phrase. It starts with the colon ":" which means the slice starts at the beginning of the string, and since no end index is specified, it goes to the end of the string. The "-1" after the colon indicates that the step size is -1, which means the slice moves through the string backward, one character at a time. The result is a new string variable r_phrase that contains the reversed version of p_phrase
