Which of the following statements is false? O a. The sequence to the right of the for statement's keyword in must be an iterable. O b. An iterable is an object from which the for statement can take one item at a time until no more items remain. O c. One of Python's most common iterable sequences is the list, which is a comma-separated collection of items enclosed in square brackets O d. The following code totals five integers in a list: total = 0 for number in [2, -3, 0, 17, 9]: total + number

Code in Python: Your hangman game should be broken into appropriate functions, contain a main function, anddo the following:1. The program should randomly select a word from the list: kangaroo, capybara, wombat,koala, wallaby, quokka, platypus, dingo, kookaburra2. Repeatedly prompt the user to guess a letter.3. Validate the input4. All guessed letters should be stored in a two-dimensional list (from problem 2). If thenumber of times a letter has been guessed is greater than 1, then the user should benotified that they have already guessed this letter and prompted to guess a differentletter. The hangman won’t update (grow) if the same incorrect letter is guessed multipletimes.5. The word should be printed where all correctly guessed letters are revealed, and allunguessed letters are replaced with underscores6. A hangman reflecting the number of incorrect guesses should be printed7. If all the letters in the word are guessed, then the user wins. If the hangman / number ofincorrect…

The function should ask the user to enter some review dates This should be entered in the format mm/dd/yyyy (same as that in the file) where dd is two-digit day, mm is two digit month and yyyy is a four digit year e.g. 01/22/2020 The function should return a list containing the specified review dates. :return: a list of review datesYou can take any review date as sample example
Python: A group of statisticians at a local college has asked you to create a set of functions that compute the median and mode of a set of numbers. Define these functions, median and mode, in a module named stats.py. Also include a function named mean, which computes the average of a set of numbers. Each function should expect a list of numbers as an argument and return a single number. Each function should return 0 if the list is empty. Include a main function that tests the three statistical functions using the following list defined in main: lyst = [3, 1, 7, 1, 4, 10] An example of the program output is shown below: List: [3, 1, 7, 1, 4, 10] Mode: 1 Median: 3.5 Mean: 4.33333333333333 This is the code they gave me, but something is wrong or something is missing. from statistics import median def mode(lyst): fv = {} for v in lyst: fv[v] = fv.get(v, 0) + 1 mf = max(fv.values()) md = [key for key, v in fv.items() if v == mf] return md[0] lyst =…

In Python, Ask the user to enter a sentence,e.g., Computer Science is awesom. Pass the sentence to a function str2words() and convert the string/sentence into words; place individual words,e.g., 'Computer', 'Science', etc. into a list and return the list to main program. In addition, the individual words should not contain any whitespaces appended to the end of the word such as 'Science'. Do not use any built-in functions to convert a string to words.
Help with a lisp function (please post photos) A lisp function that generates a random day of the week, then displays a message saying that "Today is ... and tomorrow will be ...". For this purpose, create a global variable before the function containing the days of the week as a list. Then use the built-in function random first to generate a number between 0 and 6 (including). The expression (random) by itself generates a random integer. You can call it with one parameter to return a value within the range from 0 to the value of the parameter-1. For example, (random 10) will return a value between 0 and 9. Next, use the number generated at the previous step to retrieve the symbol for the day of the week from the list. Use the built-in elt function. We want the name of the day to appear capitalized. For this, extract the symbol-name of the day first, then apply the built-in function capitalize to it. Use the result in the princ function call, and do the same thing for the next day.…
