Write a program that generates random numbers between -25 and 25 by using the randint function. The program will add up the numbers and terminate when the sum of the values becomes zero. The program should contain the following functions: add() : add up the values main(): the function where the program execution should begin and end. randomgen(): a function that returns a number between -25 and 25 A global variable subsetsum that keeps track of the sum The program should output the count of the number of values generated before exiting saying that the subset sum was zero.

Define function print_popcorn_time() with parameter bag_ounces. If bag_ounces is less than 3, print "Too small". If greater than 10, print "Too large". Otherwise, compute and print 6 * bag_ounces followed by "seconds". End with a newline. Remember that print() automatically adds a newline. Sample output with input: 7 42 seconds
IN PHP PROgramming The ABACABA pattern is a recurring fractal pattern that is seen in many places in the real world (such as geometry, art, music, poetry, numerical systems, books and high magnitude). Create a function that takes the number n as an argument and returns the character unit that represents the full pattern. Examples abacabaPattern (1) → "A" abacabaPattern (2) → "ABA" abacabaPattern (3) → "ABACABA"
A number is said to be Harshad if it's exactly divisible by the sum of its digits. Create a function that determines whether a number is a Harshad or not. Examples isHarshad (75) → false // 7 + 5 = 12 // 75 is not exactly divisible by 12 isHarshad (171) → true // 1 + 7 + 1 = 9 // 9 exactly divides 171 isHarshad (481) → true isHarshad (89) → false isHarshad (516) → true isHarshad (200) → true
Create a function that counts the integer's number of digits. Examples count (318) → 3 count (-92563) → 5 count (4666) -4 count (-314890) -6 count (654321)→ 6 count (638476) <- 6
Create a function that takes a string of words and returns the word with the highest score. Each letter of the word gets points according to its position in the alphabet: a = 1, b = 2, C = 3, etc. Examples wordRank ("A quick brown fox.") → "brown" wordRank ("Nancy is very pretty.") "pretty" wordRank ("Come back tomorrow, man!") → "tomorrow" wordRank ("Wednesday is hump day.") "Wednesday" Solution in JS 10

please code in python:def best(len_score,lst): max1=0 for i in reversed(lst): temp = len_score(i) if temp >= max1: max1 = temp ans = i return ans The best function should be able to take any scoring function and return the result. Define a function, number_of_vowels, that returns the number of vowels in a string. Pass it to your best function to find the name in names with the most vowels. See how easy it is to change the score function for different functionalities! Example: names = ["Ben", "April", "Zaber", "Alexis", "McJagger", "J.J.", "Madonna"] best(number_of_vowels, names) -> 'Alexis'
A prime number is an integer value that is only divisible by 1 and itself. 2, 3, 5, 7, and 11 are examples of prime numbers. You have been provided with two function definitions: The is_prime () function takes an integer parameter number, and returns True if number is prime and False otherwise. The get_next_prime () function also takes a single integer parameter number, and returns the first prime number larger than it. You must not change the implementation of these 2 functions. Complete the get_primes_list() function that takes a single list of integers called numbers as parameter. You can assume that the integer items in this list will be non-negative. The function must update this list so that items that are not prime numbers are updated to the first prime number larger than them. To implement this function you must call both the is_prime () and get_next_prime () functions. Some examples of the function being called are shown below. Note: the get_primes_list() function does not…
Compute and Plot the ROC Curve Write a function from scratch called roc_curve_computer that accepts (in this exact order): a list of true labels a list of prediction probabilities (notice these are probabilities and not predictions - you will need to obtain the predictions from these probabilities) a list of threshold values. The function must compute and return the True Positive Rate (TPR, also called recall) and the False Positive Rate (FPR) for each threshold value in the threshold value list that is passed to the function. Important: Be sure to reuse functions and code segments from your work above! You should reuse two of your above created functions so that you do not duplicate your code. The function you will write behaves identically to Scikit-Learn's roc_curve function, except that it will take the list of thresholds in as input rather than return them as output. Your function must calculate one value of TPR and one value of FPR for each of the threshold values in the list.…
Problem DNA: Subsequence markingA common task in dealing with DNA sequences is searching for particular substrings within longer DNA sequences. Write a function mark_dna that takes as parameters a DNA sequence to search, and a shorter target sequence to find within the longer sequence. Have this function return a new altered sequence that is the original sequence with all non-overlapping occurrences of the target surrounded with the characters >> and <<. Hints: ● String slicing is useful for looking at multiple characters at once. ● Remember that you cannot modify the original string directly, you’ll need to build a copy. Start with an empty string and concatenate onto it as you loop. Constraints: ● Don't use the built-in replace string method. All other string methods are permitted. >>> mark_dna('atgcgctagcatg', 'gcg') 'at>>gcg<<ctagcatg' >>> mark_dna('atgcgctagcatg', 'gc')…
