Write a function called count_items() that takes a list and returns a dictionary that contains the number of times list items occurred. Write Python statements that test your function. Part-2: Sample list= ['Mercedes', 'Bentley', 'Audi', 'Bentley', 'Tesla', 'Mercedes'] Result= {'Mercedes': 2, 'Bentley': 2, 'Audi': 1, 'Tesla': 1}

Write a python program... Write a function called merge2(d1,d2) that takes two dictionaries as input parameters. This function will create a new dictionary that contains everything from the two input dictionaries and return it. The same key might appear in both input dictionaries. In the output dictionary, the value for each key will be a list that has all values corresponding to this key in the two input dictionaries. Sample run,>>> d1 = {'a': 100, 'b': 200, 'c':300}>>> d2 = {'a': 300, 'b': 200, 'd':400} >>> d3 = merge2(d1,d2)>>> display(d3)a, [100,300]b, [200,200]c, [300]d, [400]
I am trying to write a function using python that receives a list and builds a dictionary containing the position in the list where every item last appeared.
Write a function that takes two arguments: stock and ingr (short for ingredients) and returns the missing ingredients in stock. stock is a dictionary containing (key,value) pairs in the form of ("potato", 5).The key is the name of an ingredient, and the vlaue is its existingamount. ingr is a list of tuples, where each tuple represents the requiredamount of an ingredient. For example, ("cheese", 3) means we need 3 units of cheese for this recipe. Your function checks whether we have enough of each itemin the stock. If an item is missing or not enough then your function returns the missing amount within a list of all such items. If all items are in stock, then you return an empty list. For example: stock = {"salt":100, "sugar":100, "flour":50, "apple":3, "cream":10}ingr = [("sugar",50), ("flour", 120), ("apple",5)] checkStock(stock, ingr) should return [("flour",70), ("apple",2)] which means we need 70 more units of flour and 2 more apples for this recipe.Note that it is possible for an…

Creation of a python function named b_length that bins a list of strings into a dictionary where the key is an int length of a given string and the associated values are a set of strings of the key’s length found in the original list. How it should work correctly in a test: assert b_length(["your", "quick", "code"]) == {3: {"your", "code"}, 5: {"quick"}} assert b_length(["the", "the", "code"]) == {3: {"the", "code"}}
Write a function averageB in Python that has a parameter scoreDict which is a dictionary where the keys are strings and the values are floating point numbers representing scores. The function returns the average score for all keys that start with a b (uppercase or lowercase) or returns 0 if there are no keys that start with b.
PYTHON CODEWrite a function removeRange() that takes a list of integer numbers and two integer numbers as parameters, returns a new list where the numbers between the 2nd and 3rd parameters (both inclusive) are removed from the 1st list. Assume 2nd parameter is less than the 3rd parameter.
• Create a function which takes a tuple and returns a dictionary which is a histogramto count how many times each number exists in the tuple:• The main program must take the dictionary, transform the items into a list,use sort () to order the list (in ascending order) and after that display the list. def histo_n (x):'' '(tuple) -> dictReturns a dictionaryPrecondition: the tuple contains integers>>> t = (1,2, -3,3,4, -3,3,3)>>> histo_n (t){1: 1, 2: 1, 3: 3, 4: 1, -3: 2}'' ' Subject: Python Programming

Can you answer with Python programming language ? Write a function that takes two arguments: stock and ingr (short for ingredients) and returns the missing ingredients in stock. stock is a dictionary containing (key,value) pairs in the form of ("potato", 5).The key is the name of an ingredient, and the value is its existingamount. ingr is a list of tuples, where each tuple represents the requiredamount of an ingredient. For example, ("cheese", 3) means we need 3 units of cheese for this recipe. Your function checks whether we have enough of each itemin the stock. If an item is missing or not enough then your function returns the missing amount within a list of all such items. If all items are in stock, then you return an empty list. For example: stock = {"salt":100, "sugar":100, "flour":50, "apple":3, "cream":10}ingr = [("sugar",50), ("flour", 120), ("apple",5),("orange",25),("salt",40)] checkStock(stock, ingr) should return [("flour",70), ("apple",2),("orange",25)] which means we need…
Assume that L is a list of Boolean values, True and False. Write a program in python with a function longestFalse(L) which returns a tuple (start, end) representing the start and end indices of the longest run of False values in L. If there is a tie, then return the first such run. For example, if L is False False True False False False False True True False False 0 1 2 3 4 5 6 7 8 9 10 then the function would return (3, 6), since the longest run of False is from 3 to 6.
Please answer it in Python Write a function min_pair that takes a list as an argument and returns the smallest even integer contained in the list. If the list contains no even integers, the function will return None. Example: min_pairs([4, 7, 12, 0, 21, 5]) is 0 min_pairs([9, 3, 1]) is None. min_pair([16, 13, 10, 102, 7, 23]) is 10
