For this assignment, you will develop working examples of a graphical user interface (GUI) and event handling and that demonstrate the following:


Working code with screenshots of a Python GUI application that includes 5 design widgets of your choosing


Working code with screenshots of event handling in Python based on 3 events of your choosing


Be sure to include a brief narrative of your code where you explain what the code is doing.

Documentation Guidelines:

Use good programming style (e.g., indentation for readability) and document each of your program parts with the following items (the items shown between the '<' and '>' angle brackets are only placeholders.  You should replace the placeholders and the comments between them with your specific information).  Your cover sheet should have some of the same information, but what follows should be at the top of each program's sheet of source code.  Some lines of code should have an explanation of what is to be accomplished, this will allow someone supporting your code years later to comprehend your purpose.  Be brief and to the point.  Start your design by writing comment lines of pseudocode.  Once that is complete, begin adding executable lines.  Finally run and test your program.

Let A and B be two stations attempting to transmit on an Ethernet. Each has a steady queue of frames ready to send; A’s frames will be numbered ?1, ?2 and so on, and B’s similarly. Let ? = 51.2 ???? be the exponential backoff base unit. Suppose A and B simultaneously attempt to send frame 1, collide, and happen to choose backoff times of 0 × ? and 1 × ?, respectively. As a result, Station A transmits ?1 while Station B waits. At the end of this transmission, B will attempt to retransmit ?1 while A will attempt to transmit ?2. These first attempts will collide, but now A backs off for either 0 × ? or 1 × ? (with equal probability), while B backs off for time equal to one of 0 × ?, 1 × ?, 2 × ? and 3× ? (with equal probability).

What is the probability that A wins all the ? backoff races. (? is a given constant)

Program 3: Give a baby $5,000! Did you know that, over the last century, the stock market has returned an average of 10%? You may not care, but you’d better pay attention to this one. If you were to give a newborn baby $5000, put that money in the stock market and NOT add any additional money per year, that money would grow to over $2.9 million by the time that baby is ready for retirement (67 years)! Don’t believe us? Check out the compound interest calculator from MoneyChimp and plug in the numbers!

To keep things simple, we’ll calculate interest in a simple way. You take the original amount (called the principle) and add back in a percentage rate of growth (called the interest rate) at the end of the year. For example, if we had $1,000 as our principle and had a 10% rate of growth, the next year we would have $1,100. The year after that, we would have $1,210 (or $1,100 plus 10% of $1,100). However, we usually add in additional money each year which, for simplicity, is included before calculating the interest.

Your task is to design (pseudocode) and implement (source) for a program that 1) reads in the principle, additional annual money, years to grow, and interest rate from the user, and 2) print out how much money they have each year. Task 3: think about when you earn the most money!

Lesson learned: whether it’s your code or your money, save early and save often…

Sample run 1:

Enter the principle: 2000

Enter the annual addition: 300

Enter the number of years to grow: 10

Enter the interest rate as a percentage: 10

Sample run 2 (yeah, that’s $9.4MM):

Enter the principle: 5000

Let A and B be two stations attempting to transmit on an Ethernet. Each has a steady queue of frames ready to send; A’s frames will be numbered ?1, ?2 and so on, and B’s similarly. Let ? = 51.2 ???? be the exponential backoff base unit. Suppose A and B simultaneously attempt to send frame 1, collide, and happen to choose backoff times of 0 × ? and 1 × ?, respectively. As a result, Station A transmits ?1 while Station B waits. At the end of this transmission, B will attempt to retransmit ?1 while A will attempt to transmit ?2. These first attempts will collide, but now A backs off for either 0 × ? or 1 × ? (with equal probability), while B backs off for time equal to one of 0 × ?, 1 × ?, 2 × ? and 3× ? (with equal probability). (a) Give the probability that A wins this second backoff race immediately after his first collision. (b) Suppose A wins this second backoff race. A transmits ?2 and when it is finished, A and B collide again as A tries to transmit ?3 and B tries once more to transmit ?1. Give the probability that A wins this third backoff race immediately after the first collision. (c) What is the probability that A wins all the ? backoff races. (? is a given constant) (d) Assume that there are 3 stations sharing the Ethernet. Will the chance for A to win all the backoff races decrease or increase? Why?

What python codes should I use to solve this question below?

Use input() function once to retrieve an input and assign that input value to a variable. Check if the input contains the string “an”. If so, use input() function one more time to retrieve an input and assign the new input value to a different variable. Now, replace “an” characters in the first variable with the first two characters of the second variable if only the second variable has at least two characters
