Which part of the computer coordinates all computer operations and performs arithmetic and logical operations on data
Answer:
A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions. The term has been used in the computer industry at least since the early 1960s.
Provide your own examples of the following using Python lists. Create your own examples. Do not copy them from another source. Nested lists The “*” operator List slices The “+=” operator A list filter A list operation that is legal but does the "wrong" thing, not what the programmer expects Provide the Python code and output for your program and all your examples.
Lists are used in Python to hold multiple values in one variable
(a) Nested list
A nested list is simply a list of list; i.e. a list that contains another list.
It is also called a 2 dimensional list.
An example is:
nested_list = [[ 1, 2, 3, 4] , [ 5, 6, 7]]
(b) The “*” operator
The "*" operator is used to calculate the product of numerical values.
An example is:
num1 = num2 * num3
List slices
This is used to get some parts of a list; it is done using the ":" sign
Take for instance, you want to get the elements from the 3rd to the 5th index of a list
An example is:
firstList = [1, 2 ,3, 4, 5, 6, 7]
secondList = firstList[2:5]
The “+=” operator
This is used to add and assign values to variables
An example is:
num1 = 5
num2 = 3
num2 += num1
A list filter
This is used to return some elements of a list based on certain condition called filter.
An example that prints the even elements of a list is:
firstList = [1, 2 ,3, 4, 5, 6, 7]
print(list(filter(lambda x: x % 2 == 0, firstList)))
A valid but wrong list operation
The following operation is to return a single list, but instead it returns as many lists as possible
def oneList(x, myList=[]):
myList.append(x)
print(myList)
oneList(3)
oneList(4)

What is the result of the following code?
x=7//2+10%2**4
print(x)
Answer:
3
Explanation:
We can split the expression into two sections
First Section:
7 // 2 = 3. Using the floor division we only utilize the integer part.
Second Section:
10 % 2**4 = 0**4 = 0
Bringing back the full version expression we have
3 + 0 = 3

Answer:
Hybrid Data Marts
A hybrid data mart allows you to combine input from sources other than a data warehouse. This could be useful for many situations, especially when you need ad hoc integration, such as after a new group or product is added to the organization.
