Question 3. Define a function that satisfies the following specifications. generate_ qns from list 1. A list. Function Parameters Each element of this list is a list of integers. 1. A list of dictionary objects Return Value Detail Information This function should convert the list parameter into a list of dictionaries. Each dictionary will have two string-typed keys – "qns" and "ans". The value for the "qns" key will be a str of the integers taken from each list element in the list parameter. In the str, the integers are separated with the characters " + ". The value for the "ans" key will be the sum of all the numbers in the list. You should skip the lists that contain fewer than 2 integers. There is no need to print anything out.

create a function in python parameters: 1. dict[str, list[str]] 2. list[str] return type: dict[str, list[str]] must do like this: 1. establish an empty dictionary that will serve as the dictionary returned at the end 2. loop thorugh each of the columns in the second parameter of the function 2a. asssign to the column key of the result dictionary the list of values stored in the input dictionary at the same column 3. return the dictionary produced do not import other libraries such as pandas, .select, .head, .iloc or anything this function is being used to work in a dataframe
Write a function named dictMax which takes two arguments: a dictionary and a list. Your function must look for the keys provided in the list argument, within the dictionary argument and return the maximum of the corresponding values. For example: dictMax({1:3, 3:2, 4:5, 2:6, 7:-1, 6:-3}, [3,2,6]) will return 6, because key 3 in the dictionary corresponds to value 2, key 2 to value 6 and key 6 to value -3, and among 2, 6 and -3, the maximum is 6. If a key does not exist in the dictionary, you should omit it. If none of the keys exist in the dictionary, you should return None.
python question Define a function named filter_list with three parameters: the 1st parameter, called k in this description, is a string; the 2nd parameter, called v in this description, is a string; the 3rd parameter, called lst in this description, is a list of dictionaries. Your filter_list function should use the accumulator pattern to return a new list. Each dictionary in lst which includes k:v as a key-value pairing should be added to the accumulator. You SHOULD assume that all of lst's dictionaries have k as a key.
void dict_clear (dict_t* dict); This function clears the dictionary dict, destroying each pair key/value, but does not destroy dict itself (remember that dict was allocated using dict_create, so it will need to be freed at some point, but this is not this function’s job.) This is now the function that frees (destroys) a dictionary: void dict_destroy (dict_t* dict); This operates just as dict_clear, but in addition should free the memory that was allocated during dict_create. After a call to this function, if any other library function receives the pointer dict, the behavior is undefined (most likely, it will crash). This simple function returns the current size of the dictionary: size_t dict_size (const dict_t* dict);

get_movie_dict() takes a 2-D list similar to movie_db and a dictionary similar to ratings as the parameters and returns a dictionary, where each {key: value} of this dictionary is {a valid movie id: a list containing the name of the movie, the year it got released, and the average rating of this movie}. I will refer to this dictionary as movies.>>> movies = get_movie_dict(movies_db, ratings)>>> display_dict(movies)1: ['Toy Story', 1995, 3.92]2: ['Jumanji', 1995, 3.43]3: ['Grumpier Old Men', 1995, 3.26]4: ['Waiting to Exhale', 1995, 2.36]5: ['Father of the Bride Part II', 1995, 3.07]6: ['Heat', 1995, 3.95]7: ['Sabrina', 1995, 3.19]8: ['Tom and Huck', 1995, 2.88]9: ['Sudden Death', 1995, 3.12]10: ['GoldenEye', 1995, 3.5]11: ['American President The', 1995, 3.67]12: ['Dracula: Dead and Loving It', 1995, 2.42]13: ['Balto', 1995, 3.12]14: ['Nixon', 1995, 3.83]15: ['Cutthroat Island', 1995, 3.0]16: ['Casino', 1995, 3.93]17: ['Sense and Sensibility', 1995, 3.78]18: ['Four…
3. form_letter This function takes a list of dictionaries, where each dictionary has an entry of key "name" and entry of key "date". It returns a list of strings, where each output string has replaced the name and the date into the following template. Use the format method on strings -- see Lecture 8! The template should be exactly like this -- just copy-paste this into your code. TEMPLATE = """Dear {name},Your appointment is at {time}.Thanks very much.-- bimmy""" It can be either local to your function, or global in your Python file. Your choice! Sample calls should look like this. >>> form_letter([{"name":"Alex", "time":"three o'clock"},{"name":"Laura", "time":"the stroke of midnight"}])["Dear Alex,\nYour appointment is at three o'clock.\nThanks very much.\n-- bimmy", 'Dear Laura,\nYour appointment is at the stroke of midnight.\nThanks very much.\n-- bimmy']
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') []
Find Country Function Name: findCountry() Parameters: capitalList ( list ) Returns: Dictionary mapping each capital to its country( dict ) Description: Given a list of countries' capital cities, write a function that returns a dictionary that maps a capital to its country's name. Note: Assume that all capital cities provided are valid. example test cases: >>> findCountry(('tokyo', 'delhi', 'stockholm']) {'tokyo': 'Japan', 'delhi": 'India', 'stockholm': 'Sweden'} >>> findCountry(l'paris', 'canberra', 'copenhagen']) {'paris': 'France', 'canberra': 'Australia', 'copenhagen': 'Denmark'} For this assignment, use the REST countries API (https://restcountries.com/#api-endpoints-v2). For all of your requests, make sure you to use version 2 of the REST countries API (V2), not version 3 (V3.1). If you make a request with the URL: https://restcountries.com/v2/alpha/usa, you will receive the following response: { "name": "United States of America", "topLevelDomain": [".us"], "alpha2Code": "US",…
