Create a solution that accepts three integer inputs representing the number of times an employee travels to a job site. Output the total distance traveled to two decimal places given the following miles per employee commute to the job site. Output the total distance traveled to two decimal places given the following miles per employee commute to the job site: Employee A: 15.62 miles Employee B: 41.85 miles Employee C: 32.67 miles The solution output should be in the format Distance: total_miles_traveled - commute = { 'Employee A': 15.62, 'Employee B': 41.85, 'Employee C': 32. } travels = { 'Employee A': int(input()), 'Employee B': int(input()), 'Employee C': int(input()) } t_d_t = sum(commute[employee]*travels[employee] for employee in travels) print(f'Distance: {t_d_t:.2f} miles') Create a Python solution to the following task. Ensure that the solution produces output in exactly the same format shown in the sample(s) below, including capitalization and whitespace. Task: Create a solution that accepts an integer input representing any number of ounces. Output the converted total number of tons, pounds, and remaining ounces based on the input ounces value. There are 16 ounces in a pound and 2,000 pounds in a ton. The solution output should be in the format
Tons: value_1 Pounds: value_2 Ounces: value_3 - opp = 16 top = 2000 ounces = int(input()) tons = ounces // (opp * top) ro = ounces % (opp * top) pounds = ro // opp ro %= opp print(f'Tons: {tons}') print(f'Pounds: {pounds}') print(f'Ounces: {ro}') Create a solution that accepts an integer input representing the index value for any any of the five elements in the following list: various_data_types = [516, 112.49, True, "meow", ("Western", "Governors", "University"), {"apple": 1, "pear": 5}] Using the built-in function type() and getting its name by using the .name attribute, output data type (e.g., int", "float", "bool", "str") based on the input index value of the list element. The solution output should be in the format Element index_value: data_type - I_V = int(input()) if -1 <= I_V < len(various_data_types): element = various_data_types [I_V] D_T_N = str(type(element)).split("'")[1] print(f' Element {I_V}: {D_T_N}') Create a solution that accepts any three integer inputs representing the base (b1, b2) and height (h) measurements of a trapezoid in meters. Output the exact area of the trapezoid in square meters as a float value. The exact area of a trapezoid can be calculated by finding the average of the two base measurements, then multiplying by the height measurement.
Task: Create a solution that accepts an integer input representing a 9-digit unformatted student identification number. Output the identification number as a string with no spaces. The solution output should be in the format 111-22-3333 - id_num = int(input()) format_id_num = f'{id_num // 1000000}-{(id_num // 10000) % 100}-{id_num % 10000:04d}' print(format_id_num) Task: Create a solution that accepts an integer input to compare against the following list: predef_list = [4, -27, 15, 33, -10] Output a Boolean value indicating whether the input value is greater than the maximum value from predef_list The solution output should be in the format Greater Than Max? Boolean_value - user = int(input()) greater_than = user > max(predef_list) print(f'Greater Than Max? {greater_than}') Task: Create a solution that accepts one integer input representing the index value for any of the string elements in the following list: frameworks = ["Django", "Flask", "CherryPy", "Bottle", "Web2Py", "TurboGears"] Output the string element of the index value entered. The solution should be placed in a try block and implement an exception of "Error" if an incompatible integer input is provided. The solution output should be in the format frameworks_element - try:
index = int(input()) if 0 <= index < len(frameworks): print(frameworks[index]) else: raise ValueError("Error") except ValueError: print("Error") Task: Create a solution that accepts an integer input representing water temperature in degrees Fahrenheit. Output a description of the water state based on the following scale: If the temperature is below 33° F, the water is "Frozen". If the water is between 33° F and 80° F (including 33), the water is "Cold". If the water is between 80° F and 115° F (including 80), the water is "Warm". If the water is between 115° F and 211° (including 115) F, the water is "Hot". If the water is greater than or equal to 212° F, the water is "Boiling". Additionally, output a safety comment only during the following circumstances: If the water is exactly 212° F, the safety comment is "Caution: Hot!" If the water temperature is less than 33° F, the safety comment is "Watch out for ice!" The solution output should be in the format water_state optional_safety_comment - temperature = int(input()) if temperature < 33: water_state = "Frozen" safety_comment = "Watch out for ice!" elif 33 <= temperature <= 80: water_state = "Cold" safety_comment = None elif 80 < temperature <= 115:
total_cost += stocks[stock_selection] print(f"Total price: ${total_cost:.2f}") Task: Create a solution that accepts a string input representing a grocery store item and an integer input identifying the number of items purchased on a recent visit. The following dictionary purchase lists available items as the key with the cost per item as the value. purchase = {"bananas": 1.85, "steak": 19.99, "cookies": 4.52, "celery": 2.81, "milk": 4.34} Additionally, If fewer than ten items are purchased, the price is the full cost per item. If between ten and twenty items (inclusive) are purchased, the purchase gets a 5% discount. If twenty-one or more items are purchased, the purchase gets a 10% discount. Output the chosen item and total cost of the purchase to two decimal places. The solution output should be in the format item_purchased $total_purchase_cost - purchase = {"bananas": 1.85, "steak": 19.99, "cookies": 4.52, "celery": 2.81, "milk": 4.34} item_name = input().lower() num_items = int(input()) if num_items < 10: total_cost = purchase[item_name] * num_items elif 10 <= num_items <= 20: total_cost = (purchase[item_name] * num_items) * 0. else: total_cost = (purchase[item_name] * num_items) * 0. print(f"{item_name} ${total_cost:.2f}")
Task: Create a solution that accepts an input identifying the name of a text file, for example, "WordTextFile1.txt". Each text file contains three rows with one word per row. Using the open() function and write() and read() methods, interact with the input text file to write a new sentence string composed of the three existing words to the end of the file contents on a new line. Output the new file contents. The solution output should be in the format word word word sentence - file_name = input() with open(file_name, 'r') as file: lines = file.readlines() if len(lines) == 3: word1, word2, word3 = [line.strip() for line in lines] else: print("Input file should contain exactly three words.") exit(1) sentence = f"{word1} {word2} {word3}" with open(file_name, 'a') as file: file.write('\n' + sentence) with open(file_name, 'r') as file: updated_contents = file.read() print(updated_contents) Task:
