Suppose you have a dictionary of survey responses: keys are student names values are favourite ice cream flavours (e.g. "chocolate", "vanilla", "strawberry", etc.) Write a function that takes a dictionary of survey responses and returns a new dictionary where: keys are ice cream flavours and values are number of students with that favourite flavour. For example: Test survey = {"Howlett": "vanilla", "Grey": "chocolate", "Munroe": "vanilla", "Summers": "strawberry", "Xavier": "strawberry", "Drake": "strawberry"} print (survey_results (survey)) Result {'vanilla': 2, 'chocolate': 1, 'strawberry': 3}
The programming language is - Python a. Write a function called daysOver that takes three arguments: a dictionary, a location (such as ‘Sydney’, ‘Adelaide’,etc) and a temperature and returns the number of days that were over the given temperature for the given location. For example, if we call the function using the line: total = daysOver(dictionaryData, ‘Adelaide’, 40) total will hold the number of days that Adelaide had a temperature greater than 40 celsius in the data. As a test, there were 54 days over 40 celsius in the data. Check that total is 54 for the example when you run your code. b. Use the daysOver function to print the number of days over 35 celsius for each of the following cities: 'Adelaide','Perth','Melbourne','Canberra','Sydney','Brisbane','Darwin' c. Which of the Australian cities has the most number of days over 35 celsius? My spreadsheet looks like this Since I cannot attach an excel file, my excel file name is "weatherAUS.csv"
Presentation exercise 2 Write a function (including docstring) called multiply_term that takes a polynomial as inputs and a term. We can represent polynomials as a collection or power-coefficient pairs. Consider the following polynomial: p(x) = 2 - a4 – 3. x+ 5. We can represent it as the following collection of pairs: (4, 2), (1, -3), (0, 5). We can represent a term as a tuple where the first value indicated the exponent in the term, and the second its coefficient. For example, the term 5 - a* is represented by the tuple (4, 5). The function does not return anything, but after its execution the input dictionary will now represent the multiplication of the input polynomial by the specified term. For example: Page 2 >> p = {2 : 1, 1 : 2} # x^2 + 2x >>> t = (4, 5) # 5x^4 >>> multiply_term(p, t) >>> p == {6 : 5, 5 10} True You can assume that the function will receive as input a dictionary mapping integers to numbers. No need for you to implement any type of input validation.
Task 01 Write a function that takes a dictionary as a parameter. The dictionary holds student names as keys and their mid-term marks in the python course as values. Your function should get the student name corresponding to the minimum and maximum mark achieved by the student and return it to the function call. Then, finally prints the returned statement after the function call. Sample Input: {'Samin': 25, 'Lily': 28,'Akib': 17,'Salma': 22, 'Imon': 20 } Function Call: function_name({'Samin': 25, 'Lily': 28,'Akib': 17,'Salma': 22, 'Imon': 20 }) Sample Output: Highest scorer: Lily Lowest scorer: Akib Sample Input: {"A":60,"B":30,"P":2, "R":8, "S":33, "T":88} Function Call: function_name({"A":60,"B":30,"P":2, "R":8, "S":33, "T":88}) Sample Output: Highest scorer: T Lowest scorer: P
Part 3: Time for a Financial Checkup Complete the function financial_checkup, which takes a dictionary representing your monthly budget for certain categories of expenditures (budget), and a dictionary that represents how much you actually spent in each category (outlays). The function then creates and returns a new dictionary of those categories in which you overspent and the excess amount. Specifically, the returned dictionary maps the category name to the amount of excess spending, given as a negative number. If a category appears in outlays, but not budget, we interpret this to mean that we budgeted $0 for that category, so the entire amount in outlays is considered to be excess spending. Example #1: budget: spent returned: {'food' -95, 'travel': -100} Example #2: budget: spent {'food': 125, 'gas': 75, 'travel': 400} {'food' 220, 'gas': 10, 'travel': 500} Example #3: {'food' 100, 'gas': 30} {'food' 220, 'gas': 10, 'travel': 500} returned: {'food": -120, 'travel': -500} {'drinks'…
Write a function called daysOver that takes three arguments: a dictionary, a location (such as ‘Sydney’, ‘Adelaide’,etc) and a temperature and returns the number of days that were over the given temperature for the given location. For example, if we call the function using the line: total = daysOver(dictionaryData, ‘Adelaide’, 40) total will hold the number of days that Adelaide had a temperature greater than 40 celsius in the data. As a test, there were 54 days over 40 celsius in the data. Check that total is 54 for the example when you run your code. Use the daysOver function to print the number of days over 35 celsius for each of the following cities: 'Adelaide','Perth','Melbourne','Canberra','Sydney','Brisbane','Darwin' Which of the Australian cities has the most number of days over 35 celsius?
The function to compute the cost and print the receipt Write a function to print the formatted output and return the total price for the selected car wash services. Write a function car_wash_service() that takes the following parameters: • a base price for a car wash, • a dictionary that lists the services and their prices, • two strings that contain the names of the services that were selected. For example, if no services were selected and the provided base price is 10 dollars, the function prints the following: ZyCar Wash Base car wash ---- -- $10.00 Total price: $10.00 Notice that the output that you see above is produced from within the function. 1. In your function, you need to extract the cost of each service based on the provided values. 2. Calculate the total for the services: the base car wash and the two additional services. 3. Print the receipt of all selected services with their cost, then the total price. Hint: Use the service name values to index the dictionary - this…
ISBNThis problem is slightly more difficult than the above problem. This one requires a data type that stores 10 digits. BackgroundPublishers and bookstores use a number system called the International Standard Book Number (ISBN) system to identify books. At the start of publication, each book is assigned a unique ISBN. An ISBN, once assigned, can never be re-used. Click here for detailed information on this numbering system.An ISBN consists of exactly 10 digits. The rightmost digit is the check digit. The check digit is validated modulo 11.• multiply each digit from the first to the ninth by a weight from 10 to 2 respectively (the first digit by 10, the second by 9,.., the ninth by 2).• the sum of the products plus the check digit should be divisible without remainder by 11.• if there is a remainder, the whole number is not a valid ISBN SpecificationsDesign a program that validates an ISBN. Your program keeps accepting a whole number and determining if that whole number is a valid…
Implement the following function: 1) Name: GenerateRandom 2) Parameters: a (int), b (int), N (int) 3) Job: Generate and display N random numbers in the range [a – b] including a and b. The function will display the random numbers, display their sum and return the average of all random numbers. The main() is provided. All you need is to implement the function GenerateRandom(). Note: Your output will be different because numbers are generated randomly. use C++
Please help with the assignment! Language is C. Answer as simply as you can as it is an Intro to C class. Write two functions, total_product and total_sum. Both functions return an integer. Total_product function takes in a 2D array of integers along with an integer with the number of rows and columns. This function will return an integer with the product of the sum of the rows. See example for details. The total_sum function takes in an array of integers with the size of the array. The total_sum function will find the sum of the 1D array. You must call the total_sum function in the total_product to receive full credit. Example: row/column 0 1 2 3 total_sum(row) Result 0 1 2 3 4 10 1 5 6 7 8 26 Given this 2D array above, the answer for total_product would be 260. Because row one adds up to be 10, and row two adds up to be 26. We multiple this together to get total product.
