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.

If so, delete 'Jim' and its associated value. 2.Write code to create a set with the following integers as members: 10, 20, 30, and 40. 3.Assume each of the variables set1 and set2 references a set. Write code that creates another set containing all the elements of set1 and set2, and assigns the resulting set to the variable set3.

Write a function named count_vowels that accepts a string as an argument. The function should count the number of times each vowel (the letters a, e, i, o, and u) appears in the string, and store those counts in a dictionary. When the function ends, the dictionary should have exactly 5 elements. In each element, the key will be a vowel (lowercase) and the value will be the number of times the vowel appears in the string.
PYTHON LANGUAGE
This code is a part of a C dictionary. Please write the code for the below requirements. dict_get Next, you will implement: char* dict_get (const dict_t* dict, const char* key); This function goes through the list given by dict. If you use the above structure, this means starting at el = dict->head and checking each time whether the key at el is key; if it is not, we set el = el->next, until either key is found, or we reach el == NULL. To compare key with el->key, we need to compare one by one each character in key with those in el->key. Remember that strings in C are just pointers (memory addresses) to the first character in the string, so comparing el->key == key will not do what you want. So how do you even get the length of a string s? You would start at memory location s and advance as long as the byte at s (i.e. *s) is not the end-of-string marker (\0, the NULL character). This can get a bit messy, so luckily, you are allowed to use the string comparison…

▾ Part 1: Sin Tax Syntax [NEW PROBLEM] Complete the function sin_tax, which computes and returns the total cost to purchase several items, some of which might be subject to sin taxes. The function takes three arguments: • items: a list of items to purchase (strings). If an item appears more than once, this means we want to buy it more than once. • prices! a dictionary that maps an item (string) to its price (float) • tax rates: a dictionary that maps an item (string) to its sin tax rate (float). The rate is given as a decimal (e.g., 0.08 to represent 8%). If an item from items does not appear in tax rates, then that item is not subject to a sin tax. Assume that every string in items is a valid key in prices. Example #1: items: ['beer', 'wine', 'cigarettes'] prices: {'beer': 18.95, 'cigarettes': 12, 'wine': 20.0} tax_rates: {'beer': 0.03, 'cigarettes': 0.1, wine': 0.05) Returned: 53.72 Example #2: ['wine', 'beer', 'wine', 'cigarettes', 'wine'] {'beer': 15.5, 'cigarettes': 13, 'soda':…
