zeroTriples.py: Write a program that reads a list of integers from the user, until they enter -12345 (the -12345 should not be considered part of the list). Then find all triples in the list that sum to zero. You can assume the list won’t contain any duplicates, and a triple should not use the same number more than once. For example: $ python3 zeroTriples.py 1 2 4 -12345 0 triples found $ python3 zeroTriples.py -3 1 4 2 -12345 1 triple found: 1, 2, -3 $ python zeroTriples.py -9 1 -3 2 4 5 -4 -1 -12345 4 triples found: -9, 4, 5 1, -3, 2 -3, 4, -1 5, -4, -1

- The mean of a list of numbers is its arithmetic average. The median of a list is its middle value when the values are placed in order. For example, if an ordered list contains 1, 2, 3, 4, 5, 6, 10, 11, and 12, then the mean is 6, and their median is 5. Write an application that allows you to enter nine integers and displays the values, their mean, and their median.Counting hashtags Write Python code to count the frequency of hashtags in a twitter feed. Your code assumes a twitter feed variable tweets exists, which is a list of strings containing tweets. Each element of this list is a single tweet, stored as a string. For example, tweets may look like: tweets = ["Happy #IlliniFriday!", "It is a pretty campus, isn't it, #illini?", "Diving into the last weekend of winter break like... #ILLINI #JoinTheFight", "Are you wearing your Orange and Blue today, #Illini Nation?"] Your code should produce a sorted list of tuples stored in hashtag_counts, where each tuple looks like (hashtag, count), hashtag is a string and count is an integer. The list should be sorted by count in descending order, and if there are hashtags with identical counts, these should be sorted alphabetically, in ascending order, by hashtag. From the above example, our unsorted hashtag_counts might look like: [('#illini', 2), ('#jointhefight', 1),…Python write a program in python that plays the game of Hangman. When the user plays Hangman, the computer first selects a secret word at random from a list built into the program. The program then prints out a row of dashes asks the user to guess a letter. If the user guesses a letter that is in the word, the word is redisplayed with all instances of that letter shown in the correct positions, along with any letters correctly guessed on previous turns. If the letter does not appear in the word, the user is charged with an incorrect guess. The user keeps guessing letters until either: * the user has correctly guessed all the letters in the word or * the user has made eight incorrect guesses. one for each letter in the secret word and Hangman comes from the fact that incorrect guesses are recorded by drawing an evolving picture of the user being hanged at a scaffold. For each incorrect guess, a new part of a stick-figure body the head, then the body, then each arm, each leg, and finally…
- In python, The function count_contains_x takes a list of strings (wordList) and returns the count of how many strings in the list contain at least one upper- or lower-case 'x'. Hint: Use the accumulator pattern to accumulate the count. Hint: You might want to use the string method count. For example: Test Result strlist = ["xerox", "OXEN", "whiffleball", "XOXOX"] print(count_contains_x(strlist)) 3 fish = ["angel", "gold", "cat", "puffer", "damsel"] print(count_contains_x(fish)) 0 strlist = ["X", "x"] print(count_contains_x(strlist)) 2 list_of_one_x = ["x"] print(count_contains_x(list_of_one_x)) 1statistics.py: Write a program that reads a list of integers from the user, until they enter -12345 (the -12345 should not be considered part of the list). Then print the mean, median, and standard deviation of the list. The mean is the average of the numbers. The median is the “middle” value if n is odd, or the average of the two “middle” values if n is even. The standard deviation is the average amount of variability For example: $ python3 statistics.py154102-12345mean: 7.75median: 7standard deviation: 5.909032633745278JAVA: Write an application that accepts up to 20 Strings, or fewer if the user enters the terminating value ZZZ. Store each String in one of two lists: one list for short Strings that are 10 characters or fewer, and another list for long Strings that are 11 characters or more. After data entry is complete, prompt the user to enter which type of String list to display, either S for short or L for long and then output the correct list. For this exercise, you can assume that if the user does not request the list of short strings, the user wants the list of long strings. If a requested list has no Strings, output The list is empty. Prompt the user continuously until a sentinel value, ZZZ, is entered to quit the program. An example of the program is shown below: Enter a string or ZZZ to quit >> Green Enter a string or ZZZ to quit >> Green eggs Enter a string or ZZZ to quit >> Green eggs and ham Enter a string or ZZZ to quit >> I do not like green eggs and ham Enter…
- Using python, please explain 1: A positive integer greater than 1 is said to be prime if it has no divisors other than 1 and itself. A positive integer greater than 1 is composite if it is not prime. Write a program that asks the user to enter an integer greater than 1, then displays all of the prime numbers that are less than or equal to the number entered The program should work as follows: Once the user has entered a number, the program should populate a list with all of the integers from 2 up through the value entered. The program should then use a loop to step through the list. The loop should pass each element to a function that displays the element whether it is a prime number.You have a list of student ID’s followed by the course number (separated by a space) that the student is enrolled in. The listing is in no particular order. For example, if student 1 is in CS100 and CS200 while student 2 is in CS105 and MATH210 then the list might look like this:1 CS1002 MATH2102 CS1051 CS200Write a program that reads data in this format from the console. If the ID is −1 then stop inputting data. Use the HashMap class to map from an Integer (the student ID) to an ArrayList of type String that holds each class that the student is enrolled in. The declaration should look like this:HashMap<Integer, ArrayList<String>> students =new HashMap<Integer, ArrayList<String>>();After all data is input, iterate through the map and output the student ID and all classes stored in the vector for that student. The result should be a list of classes organized by student ID.Homework* - Prime factors and prime numbers: Write a program that prompts the user to enter a positive integer which is greater than one and displays all its smallest factors in decreasing order. For example, if the integer is 140, the smallest factors are displayed as 7, 5, 2, 2. Use the StackOflntegers class to store the factors (e.g., 2, 2, 5, 7) and retrieve and display them in reverse order. After that, write a program that displays all the prime numbers less than the number – which is used in the prime factors (e.g: 140)- in decreasing order. Use the StackOflntegers class to store the prime numbers (e.g., 2, 3, 5, ...) and retrieve and display them in reverse order. Here is the sample runs: To use the prime factors you must enter a positive integer which is greater than one: 140 7 5 2 2 Printing prime numbers under 140: 139 137 131 127 113 109 107 103 101 97 89 83 79 73 71 67 61 59 53 47 43 41 37 31 29 23 19 17 13 11 7 5 3 2 * This homework has a part of Challenge Question.
