a Strings > Exercise-Making a List Exercise: Making a List Lists are great. Here are some constants describing some of the things you've learned about strings so far: 6 let constants = "Declaring string constants" 7 let unicode = "Unicode characters ()" 8 let combining = "Combining strings using +" 9 let interpolation = "String interpolation (aka Fill in the Blanks)" 10 let escaping = "Escape characters for \"special powers\"" 11 let newline = "Making new lines" Experiment Make a new string constant that is a list of the things you've learned, with each entry on a new line. Make sure you add the result to the playground page so that you can see the list properly. 15 16 17 18 19 Previous | page 13 of 16 | Next: Exercise: A Restaurant 22

The function sum_evens in python takes a list of integers and returns the sum of all the even integers in the list. For example: Test Result print(sum_evens([1, 5, 2, 5, 3, 5, 4])) 6 print(sum_evens([5, 5, -5, -5])) 0 print(sum_evens([16, 24, 30])) 70

PYTHON Complete the function below, which takes two arguments: data: a list of tweets search_words: a list of search phrases The function should, for each tweet in data, check whether that tweet uses any of the words in the list search_words. If it does, we keep the tweet. If it does not, we ignore the tweet. data = ['ZOOM earnings for Q1 are up 5%', 'Subscriptions at ZOOM have risen to all-time highs, boosting sales', "Got a new Mazda, ZOOM ZOOM Y'ALL!", 'I hate getting up at 8am FOR A STUPID ZOOM MEETING', 'ZOOM execs hint at a decline in earnings following a capital expansion program'] Hint: Consider the example_function below. It takes a list of numbers in numbers and keeps only those that appear in search_numbers. def example_function(numbers, search_numbers): keep = [] for number in numbers: if number in search_numbers(): keep.append(number) return keep   def search_words(data, search_words):

Complete the reverse_list() function that returns a new string list containing all contents in the parameter but in reverse order. Ex: If the input list is: ['a', 'b', 'c'] then the returned list will be: ['c', 'b', 'a'] Note: Use a for loop. DO NOT use reverse() or reversed(). This is my code so far: def reverse_list(letters):    for x in (letters):        letters.sort(reverse=True)        return lettersif __name__ == '__main__':    ch = ['a', 'b', 'c']    print(reverse_list(ch)) # Should print ['c', 'b', 'a'] When submitting I get 4/10 and it says: Test input list ['a', 'b', 'c'] returns ['c', 'b', 'a'] Your output reverse_list() function reversed array incorrectly: ['c', 'b', 'a'] reverse_list() function should have returned: ['a', 'b', 'c']   Test input list ['a', 'b', 'c', 'd'], first element of returned list is ['d'] Your output First character of returned array should be a instead of d   Test empty input array TypeError: object of type 'NoneType' has no len()

I dont really have a full grasp on loops can someone explain to me this ?Store the list of denominators in your program as shown below:list_den = [2, 3, 4, 0, 5, 6, 8]Write a program that prompts the user for numbers and store the input numbers in a list of numerators called list_num. list_num must contain the same number of elements as list_den. If the user inputs a number that is lower than 10, display an error message and repeat the process until list_num contains numbers that are greater than or equal to 10.You will now divide a number in the list_num by the corresponding number from list_den and store the result in another list named result. You will use a loop to do this. For example, the first item in result will contain the result of dividing the first item in the list_num by the first item in list_den, and so on.Since list_den contains a denominator with the value 0, you will need to store -1 as the result when a division by zero is attempted.

***python only*** Write a program that prompts the user for floating-point numbers until the user enters the word 'end' all by itself. The program should store the user-entered numbers in a list.The program will then randomly select half of those numbers and print these numbers (separated by a blank space). Hint: use a random number generator to make the randomselection.
