Python 5. Write a function named grade_components that has one parameter, a dictionary. The keys for the dictionary are strings and the values are lists of numbers. The function should create a new dictionary where the keys are the same strings as the original dictionary and the values are tuples. The first entry in each tuple should be the weighted average of the non-negative values in the list (where the weight was the number in the 0 position of the...
USING PYTHON! a) Programmatically (do not just write a definition!) create a dictionary whose keys are the integers 1 through 10 and whose respective values are the keys cubed (e.g. a key of 5 has a value of 125). b) Write a function that, given a user inputted string, outputs a dictionary where each letter is a key and each value is the letter’s position in the string. Note that you must handle cases where a word could contain the...
Define the functions in Python 3.8 1. Write a function most frequent n that takes a list of strings and an integer n, and that returns a dictionary where the keys are the top n most frequent unique words in the list, and the values are the frequency of each word: For example, most frequent n(text, 3) should return the dictionary {'is': 2, "the’: 3, 'of': 2}, and most frequent n(text, 2) could return either {'is': 2, 'the’: 3} or...
1. use python List to Dictionary Write a function that has three parameters: a list of unsorted numbers with no duplicates, a start number, and an end number. This function should return a dictionary with all integers between the start and end number (inclusive) as the keys and their respective indices in the list as the value. If the integer is not in the list, the corresponding value would be None. Example unsorted list: [2,1,10,0,4,3] two numbers: 3, 10 returned...
they are 2 pictures attached 4) Delete set of keys from Python Dictionary Given: sampleDict = { "name": "Kelly", "age":25, "salary" : 8000, "city": "New york" } keysToRemove = ["name", "salary"] Expected output: {'city': 'New york', 'age': 25} 1) Write a Python program to iterate over dictionaries using for loops d = {'X': 10, y: 20, 'z': 30) 2) Write a Python program to get the maximum and minimum value in a dictionary my_dict = {'X':500, 'y':5874, 'z': 568} Sample...
Python 3 Write a function named starCounter that takes three parameters: 1. a dictionary named starDictionary. Each key in starDictionary is the name of a star (a string). Its value is a dictionary with two keys: the string 'distance' and the string 'type'. The value associated with key 'distance' is the distance from our solar system in light years. The value associated with key 'type' is a classification such as 'supergiant' or 'dwarf'. 2. a number, maxDistance 3. a string,...
Write a function named "loadStateDict(filename) that takes a filename and returns a dictionary of 2-character state codes and state names. The file has four columns and they are separated by commas. The first column is the state full name and the second column is the state code. You don't have to worry about column 3 & 4. You should eliminate any row that is without a state code. Save the two columns into a dictionary with key = state code...
python 3.7 write a function called read_file() which accepts a filename and returns a list of tuple objects. For example, if we have the following data: 0.000000000 192.168.0.24 10.0.0.5 H-NM 1.001451000 192.168.0.24 10.0.0.5 2.002970000 192.168.0.24 10.0.0.5 3.003552000 192.168.0.24 10.0.0.5 4.005007000 192.168.0.24 10.0.0.5 then the list should contain the following: [('192.168.0.24', 0, 84), ('192.168.0.24', 1, 84), ('192.168.0.24', 2, 84), ('192.168.0.24', 3, 84), ('192.168.0.24', 4, 84)] Note: • Each line consists of a number of fields separated by a single tab character....
Python Question? Write a function called reverse(user_list, num = -1) that takes a list and a number as parameters. The function returns a copy of the list with the first number of items reversed. Conditions: The number parameter must be a default argument. - If the default argument for number is given in the function call, only the first number of items are reversed. - If the default argument for number is not provided in the function call, then the...
python . Write the function poker_hand that takes a list of exactly five distinct Card objects as an argument, analyzes the list, and returns one of the following strings that describes the hand: "Four of a kind' (four cards of the same rank) 'Full house' (three cards of one rank, and two cards of a different rank) . 'Flush' (five cards of the same suit) 'Three of a kind' (exactly three cards of the same rank) • 'One pair' (at...
