Answer:
The correct answer is letter "A": The message is broken into independent blocks which are encrypted.
Explanation:
There are five (5) main forms of encryption: <em>Electronic Code Book (ECB), Cipher Block Chaining (CBC), Cipher Feedback (CFB), Output Feedback (OFB), and Output Feedback (OFB)</em>. Electronic Code Book (ECB) is the simplest of all of them. Using this method to encrypt information implies dividing a message into two parts to encrypt each block independently. ECB does not hide patterns effectively because the blocks are encrypted using identical plaintexts.

Answer:
Jog
Explanation:
The variable options is a list containing 5 string values
options = ["ski", "surf", "jog", "bike", "hike"]
Indexing in python starts from 0 ; hence the index values of the list values are :
0 - ski
1 - surf
2 - jog
3 - bike
4 - hike
The statement ;
print(options[2]) means print the string at index 2 in the list named options
The string at index 2 is jog ;
Hence, the string jog is printed.
Answer:
import datetime
user = input("Enter date in yyyy,m,d: ").split(",")
int_date = tuple([int(x) for x in user])
year, month, day =int_date
mydate = datetime.datetime(year, month, day)
print(mydate)
x = mydate.strftime("%B %d, %Y was a %A")
print(x)
Explanation:
The datetime python module is used to create date and time objects which makes it easy working with date-time values. The user input is converted to a tuple of integer items, then they are converted to date time objects and parsed to string with the strftime method.
Answer:
It stands for Parentheses, Exponents, Multiplication/Division, Addition/Subtraction. PEMDAS is often expanded to the mnemonic "Please Excuse My Dear Aunt Sally" in schools. Canada and New Zealand use BEDMAS, standing for Brackets, Exponents, Division/Multiplication, Addition/Subtraction.
