Prepare a report to address all aspects of the “Malware Threats and Impacts”.
If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.
Find the sum of all the multiples of 3 or 5 below 1000.
Do this using 2 methods.
Print the resulting sum each time.
The below snippet of code will download daily closing prices for SPY, which is an ETF that tracks the price S and P 500.
Using a for loop and enumerate, create a list of 5 period moving averages. For instance, the first 5 values of the list are [321.56, 319.12, 320.34, 319.44, 321.14] and the average is 320.32. This means the first entry in our new list would be 320.32.
Make your own udf to calculate the mean and use this in the for loop.
Print last 5 items of the list and the sum of the list of 5 period moving averges.

Consider the list of transactions, where each inner list item is a line item on a recipt. For instance, the first inner list ["A", "item_a"] indicates "A" bought "item_a". Iterate the list and return a dictionary where the key is the user id (A, B, C, D) and the values are a list of items the user bought.
The desired output for "A" can be seen in the sample_dct.
Do not include the first item in the list, ["User", "Item"], which can be considered a header.
Be sure your solution is scalable, meaning it should be sustainable for a list of transactions of any size.
Print the dictionary out at the end.
In [13]:
transactions = [ ["User", "Item"], ["A", "item_a"], ["B", "item_a"], ["C", "item_a"], ["C", "item_b"], ["C", "item_c"], ["B", "item_c"], ["D", "item_b"], ["D", "item_b"]]sample_dct = { "A": ["item_a"]}A string can be sliced just like a list, using the bracket notation. Find the 3 consecutive numbers and their index positions that have the greatest sum in the number 35240553124353235435234214323451282182551204321.
As an example, the the string "1324" has 2 three number windows, 132 and 324. The first sums to 6 and the later sums to 9. Thus the 3 numbers would be [3,2,4] and the indices would be [1,2,3].
Print out the 3 numbers, the 3 indices where they occur and their sum.

a = "35240553124353235435234214323451282192551204321"The sum of the squares of the first ten natural numbers is
The square of the sum of the first ten natural numbers is
Hence the difference between the sum of the squares of the first ten natural numbers and the square of the sum is
Write a function, or collection of functions, that find the difference between the square of sums and sum of squares from 1 to n. Note, to solve the problem you have to:
This can be broken up into smaller functions, with one function making use of the smaller ones, or all be done in one function.
Add an assert statement to your function, to make sure the input is a positive int.
Test the function using n=12 and n=8 and print the results.
Make a function, or group of functions, to find outlier datapoints in a list. The outlier should be based on the standard deviation, giving the user some ability to control the outlier threshold. For instance, setting 2 standard deviations or 3 from the mean should be possible. Note, to solve this problem you will have to:
(x-mean)/stdTest your data using the below stock price data for TSLA. Keep the same data range as is coded in below.
The standard deviation can be calculated as such (https://numpy.org/doc/stable/reference/generated/numpy.std.html):
std = sqrt(mean(abs(x - x.mean())**2))Print out the average, standard deviation, outliers and the index position of where the outliers occur.
Again, this can be done in one big function or a collection of smaller ones that are then used inside a final function to find the outliers.
NOTE: ASIDE FROM CHECKING WORK, THE ONLY PIECE OF IMPORTED CODE TO BE USED IS sqrt from math and the imported data from yfinance.

Instruction for the Course Project Assignment for the whole session is highlighted below in BOLD. Please read the instruction carefully.
The Course Project Assignment is an individual project draft proposal that students will develop incrementally to fully become the final paper at the end of the course. Students will add content every week when the Course Project Assignment for the week is due.
As a security manager or administrator of a fictitious company, write a Security Plan Proposal as a project draft document with the formats in the bullet points below. Please note that the project document is incremental, starting with the first Course Project Assignment for this week (week two) and ends in week eight. The Course Project Assignments (CPA) are aligned with the corresponding Chapters in your paper (as follows):
The paper format should include the following:
