Estimated Completion Time: 2 minutes You are now working for Prof. Midas on a research project. You are given this piece of code to review which is intended to be a better and faster implementation of a function that checks whether a given key is in a dictionary (i.e., key lookup). You have to present your findings to Prof. Midas. Select all the findings which you will NOT present (i.e., select all answers which are FALSE). def key_in_dict(d, k): for item in d: if k == item: return True return False This code would always be slower than the builtin key lookup Python provides. O A key lookup in a dictionary in Python is generally faster than determining whether a value is in a list. O This code is way faster and will be included in the next version of Python (version 4.1). The code is incorrect from a functional perspective, the True and False should be switched. This code could be replaced with one line: return k in d O The code is correct and would always perform faster than the…
Write a function find_key(input_dict, target_value) that takes as parameters a dictionary and a target value and returns the key in the dictionary that maps to the target value or None if no such key exists. In other words, the function finds the key such that input_dict[key] == target_value. Notes: You may assume that the target_value only appears once in the dictionary and therefore there will be only one key that maps to the target. Hint: You need to iterate over all the keys, as this task is effectively using the dictionary backwards. For example: Test Result test_dictionary = {100:'a', 20:'b', 3:'c', 400:'d'} print(find_key(test_dictionary, 'b')) 20 test_dictionary = {100:'a', 20:'b', 3:'c', 400:'d'} print(find_key(test_dictionary, 'e')) None
1. Write a Python function called add_daily_temp that is given a (possiblyempty) dictionary meant to hold the average daily temperature for each day ofthe week, a temperature value, and the day of the week for the recordedtemperature. The function should then add the temperature to the dictionaryonly if it does not already contain a temperature for that day. The functionshould return the resulting dictionary, whether it is updated or not.
13. While dictionaries are designed so that we can find a value based on a key, every so often we need to perform a reverse lookup. For example, imagine a dictionary where the keys are names and the values are phone numbers. Usually we want to find the phone number based on the name, but occasionally you might need to find a name based on the phone number. Write a function called reverse_lookup(dictionary, value) that returns all the keys in the dictionary associated with the specified value. Note: In dictionaries, the keys are guaranteed to be unique, but the values are not. So your function should return a list containing all of the matching keys (if any) Example: Given this dictionary, groups = {'Apple': 'Fruit', 'Spinach': 'Vegetable', 'Banana': 'Fruit'} reverse_lookup (groups. Vegetable') ["Spinach'] reverse_lookup (groups, Fruit') ['Apple'. 'Banana'] reverse_lookup (groups. 'Meat') []
Hi, I need help implementing this function into my code. This topic is about getting information out of text files: Function: get_total_cases() takes the a 2D-list (similar to database) and an integer x from this set {0, 1, 2} as input parameters. This function computes the total number of reported cases for each instance of x in the text file, and it stores this information in a dictionary in this form {an_instance_of_x : total_case}. Finally, it returns the dictionary and the total number of all reported cases saved in this dictionary
Write a function, young_john(people), that returns True if the dictionary people contains the key "John" with a value of 19. It should return False otherwise. like this def young_john(people):
Define a function named print_details () which takes a dictionary library as a parameter. The key of each item in the dictionary is the name of an artist, and the value is a list of tuples where each tuple contains the name and duration of a song by the artist. The function prints the details of each artist and their collection of songs as shown in the examples below. For example, if the dictionary contains a single element: {'Wiz Khalifa': [('We Own It', 227), ('See You Again', 229), ('Something New', 200)]} then the output is: Artist: Wiz Khalifa Songs: See You Again Something New We Own It Total duration: 656 seconds The function first prints the name of the artist and then prints the name of each song in the list of songs in sorted ascending order. The function should add up the duration of all the songs by a given artist and print the total duration (in seconds) of all the artist's songs. Note: • You can assume that the parameter dictionary is not empty and the values are in the…
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

Define a function named build_dictionary(words_list) that takes a list of words as a parameter. The function creates a dictionary by looping through each element in the list and creating a corresponding key: value item. The keys consist of integers and the values are lists of unique words in lowercase where the length of each word equals the key value. Note: • You can assume there will be no punctuation characters in the words in the parameter words_list (i.e. only letters). However, you should convert all words to lower case. • You can assume that the file only contains unique words. • Each list of words must be sorted in ascending order. For example: Test Result data = ['The', 'heavy', 'rain', 'is', 'to', 'ease', 'tonight', 'however', 'further', 'showers', 'Are', 'expected', 'tomorrow'] 2 ['is', 'to'] a_dict = build_dictionary (data) 3 ['are', 'the'] for key in sorted (a_dict): 4 ['ease', 'rain'] print(key, a dict[key]) 5 ['heavy'] 7 ['further', 'however', 'showers', 'tonight'] 8…

get_top_regions() that takes three input parameters; the 2-D list (similar to the database), the dictionary that stores information of all regions, and a non-zero positive integer x. This function returns a new dictionary that contains the information of top-x regions in terms of the total number of hospitalization cases recorded in these regions. That means these top-x regions have the largest numbers of hospitalization cases. Each {key:value} pair in this resulting dictionary stores the name of a top region as the key and the value is the total number of hospitalization cases reported in this region. The result does not need to be sorted, the regions of the resulting dictionary can appear in any order as long as the top-x regions have been identified correctly. If the value of x is less than 1, or more than the total number of unique regions, your function should print a message informing the user and return an empty dictionary. See sample outputs below. >>> topx_regions…
