Submission instructions

1. You should submit your homework on GitHubopen in new window.
2. For this assignment you should turn in 4 separate .py files named according to the following pattern:
   hw1_q1.py, hw1_q2.py, etc.
3. Each Python file you submit should contain a header comment block as follows:

No late submissions will be accepted.

REMINDER: Do not use any Python structures that we have not learned in class.

Question 01: Hello,You!

Write a program that asks for the user's name, their age and prints a personalized welcome message for them.

For example, an execution could look like this:

Please enter your name: Aika
Please enter your age: 29
Aika, 29, is taking CS-UY 1114.

The format of your output need not look exactly the same as ours, but it must still ask the user for their name and age, and print them out as part of some sort of sentence.

Question 02: Some Have Gone and Some Remain

The U.S. Census provides information on its web page Census.govopen in new window about the current U.S. population as well as approximate rates of change. Four rates of change are provided:

• There is a birth every 7 seconds.
• There is a death every 15 seconds.
• There is a new immigrant every 42 seconds.
• There is a new emigration (i.e. somebody moves out of the country) every 1.25 minutes.

These are, naturally, approximations of birth, death, and immigration rates, but they can assist in providing population estimates in the near term.

Write a program that takes a year as input (an integer—you may assume that this will value will always be greater than or equal to 2023) and prints out an estimated population (as an integer). Assume that the current population is 330,109,174, and assume that there are always exactly 365 days in a year.

Sample execution:

Please enter a year greater than 2023:
2042
The population in year 2042 will be 382038453

The format of your output need not look exactly the same as ours, but it must still ask the user to enter an integer representing a year, and it must always output the estimated population of that year.

Question 03: Penny Pinching

Write a program that asks the user to enter a number of quarters, dimes, nickels and pennies and then outputs the monetary value of the coins in the format of dollars and remaining cents.

Your program should interact with the user, and output its results, exactly as it is shown in the following example:

Please enter number of coins:
Number of quarters: 13
Number of dimes: 4
Number of nickels: 11
Number of pennies: 17
The total is 4 dollar(s) and 37 cent(s)

Question 04: Mad as a Hatter, Thin as a Dime

Write a program that asks the user to enter an amount of money in the format of dollars and remaining cents. The program should calculate and print the minimum number of coins (quarters, dimes, nickels and pennies) that are equivalent to the amount input by the user.

Your program should interact with the user, and display its results, exactly as it shows in the following example:

Please enter your amount of dollars and cents, in two separate lines.
4
37
4 dollars and 37 cents are: 17 quarters, 1 dimes, 0 nickels and 2 pennies

Hint: In order to find the minimum number of coins, first find the maximum number of quarters that fit within the amount of money input by the user, then find the maximum number of dimes that fit in the remaining amount, and so on.

Question 05: BMI Calculator

Body mass index (BMI) is a number calculated from a person’s weight and height. The BMI is a convenient rule of thumb used to broadly categorize the weight of a person based on tissue mass (muscle, body fat, and bone) and height (although it's really rather unreliable otherwise). The formula for BMI is the following:

PART A:

Write a program that prompts for metric weight and height and outputs the BMI. For example, an execution could look like this:

Please enter weight in kilograms: 50
Please enter height in meters: 1.58
BMI is: 20.0288415

PART B:

Write a program that prompts for weight in pounds and height in inches, converts the values to metric, and then calculates the BMI.

Note: 1 pound is equal to 0.453592 kilograms and 1 inch is equal to 0.0254 meters.

For example, an execution could look like this:

Please enter weight in pounds: 135
Please enter height in inches: 71
BMI is: 18.82849431

Both part A and part B must be written in two separate py files.

Question 06: Don't Believe The Gacha

In certain video games, you can spend either in-game currency or real money to get a series of often-random items to "improve" your gameplay experience. These mechanics are commonly referred to as gachaopen in new window, or loot boxesopen in new window, and are some of the most controversialopen in new window topics in video game development.

Let's pretend that the chances of getting a rare item in a video game are from 0% to 100%, and our video game has a player start at level 1 and end at level 5 . At level 1 , the player has an 100% chance of getting a rare item. At level 2 the player has an 80% chance of getting a rare item. At level 3 , 60%. At level 4 , 40%, and at level 5 , only 20%.

Write a program that asks the user for their current level in the video game, determines whether they have received a rare item in a loot box, and lets them know in a message.

What is your level? 1
Your loot box contains a rare item: True

What is your level? 2
Your loot box contains a rare item: False

What is your level? 3
Your loot box contains a rare item: True

What is your level? 4
Your loot box contains a rare item: False

What is your level? 5
Your loot box contains a rare item: False

Note: random

random_num = random(1, 100)

Question 07: Collective Timetables

Suppose Semi and Ollie worked for some time, and we want to calculate the total time both of them worked.

Write a program that reads a number of days, hours, and minutes minutes each of them worked,and prints the total time both of them worked together as days, hours, and minutes.

For example, an execution could look like this:

Please enter the number of days Semi has worked: 2
Please enter the number of hours Semi has worked: 12
Please enter the number of minutes Semi has worked: 15
Please enter the number of days Ollie has worked: 3
Please enter the number of hours Ollie has worked: 15
Please enter the number of minutes Ollie has worked: 20
The total time both of them worked together is: 6 days, 3 hours and 35 minutes.

Note: There are 24 hours in a day and 60 minutes in an hour.
