11. Write a Python function to check whether a number is perfect or not. Go to the editor According to Wikipedia : In number theory, a perfect number is a positive integer that is equal to the sum of its proper positive divisors, that is, the sum of its positive divisors excluding the number itself (also known as its aliquot sum). Equivalently, a perfect number is a number that is half the sum of all of its positive divisors (including itself). Example : The first perfect number is 6, because 1, 2, and 3 are its proper positive divisors, and + 2 + 3 = 6. Equivalently, the number 6 is equal to half the sum of all its positive divisors: (1 + 2 3 + 6 )/2 = 6. The next perfect number is 28 = 1 + 2 + 4 + 7 + 14. This is followed by the perfect numborc 106 ond 8128

In python, create a function adjust_values() with the arguments binaries and data. Binaries are only composed of binary values, and data are made up of integers. If binaries[0] is ‘0,’ the data should only be an even number. If it is, don’t change its value. If not, subtract 1 from it. If binaries[0] is ‘1,’ the data should only be an odd number. If it is, don’t change its value. If not, add 1 to it. Return the edited data in tuples of 3. Should the length of data be greater than the length of binaries, simply keep the remaining values as it is. To do (example below): binaries = 01001101 data = [201, 22, 93, 23, 344, 21, 53, 56, 22] The output should be in tuples of 3: [(200, 23, 92), (22, 345, 21), (52, 57, 22)]
Python Q1) Write a function get_new_grades, such that given a list of grades as an input parameter,returns a new list where the minimum score isreplaced by 50.Do not modify the initial list! Q2) Write a function compute_stats, such that given a list of grades as an input parameter,it calls the function get_new_grades (defined in the previous questions)and returns a list that contains the average value of the initial list andthe average value of the list from the get_new_grades function.
--4.Write a python program that takes an input from a user which is a sequence of any characters. Pass the input as an argument to a function. Your function should modify the given string by the user in such a way that a character does not exist in the string consecutively for more than 3 times and then return the modified string.Sample 1 input:aaaaabbbbccsshak,ckaSample output 1:aaabbbccsshak,cka.
To translate a sentence into pig Latin, create a function. When a word is written in pig Latin, its first character is dropped, shifted to the word's tail, and the letters "ay" are added. For instance, "hello world" would be "ellohay orldway" in pig Latin. Your function can be written to presume that each word has at least two letters, that there is one space between each word, and that there are no punctuation marks.
Please answer it in python Every Wednesday, words of odd length must be replaced by the word "odd". "even" wordsmust remain as they are. -Write the function Wednesday (which takes as an argument a word and returns the right one character string).
Please answer it in Python Write a function double_consonnant that takes as an argument a word and has two return values: a Boolean worth True if the word contains a double consonant (twice the same consonant in a row), and in this case the second return value is the consonant that is doubled; if there is no doubled consonant, the function must return False and None. If the word contains several double consonants (for example, 'successor'), true will be returned and the first double consonant appearing in the word. Examples: double_consonne('arrivee') is true, 'r'. double_consonne (‘bonbon’) is false, None double_consonne('appelle') is True, 'p'
Please help with my homework for the get() function in Python.

Write a python program and add a function named words_and_sents() to it. Thisfunction takes a string parameter called text. Your function should count and print thetotal number of words and sentences in the text. Assume that every word in the text is asubstring followed by a space character “ “. Also, assume that every sentence in the textis a string containing one or more words and must end with a “.” or “?” character. Finally,capitalize each sentence (i.e., convert the first letter to uppercase) and print them onseparate lines. See the sample output below.>>> text = "hello, here are some words. and some sentences. canyou count them.">>> words_and_sents(text)#sentences = 3, #words = 12Printing sentences:Hello, here are some words.And some sentences.Can you count them.
Python Write a function called count_dashes that takes a line of text as inputand outputs the number of dashes in it, as shown below. In addition to printing the requested information, return the number of dashes. The function should output (print) its findings as follows:There are DDD dashes in 'XXX'.where XXX and DDD are replaced by the appropriate values that are based on the given argument.
Please answer it in Python Write a function show_scores that takes as arguments a dictionary of score scores and a character string nature and ‑ache the scoreboard. Generally, nature will take the value "Round" or "Part" but one could imagine having other values. The order in which the players are aché ‑is irrelevant. We will respect the format of the ‑following achage obtained for the execution of For example: show_scores({'tata': 3,'titi': 12,'toto': 0}, "Round"), (with 3 space in front of each player's name): #return => Round scores: tata : 3 point(s) titi: 12 point(s) toto : 0 point(s) show_scores({'bata': 6,'biti': 1,'boto': 2}, "Part") #return => Part scores: bata : 6 point(s) biti: 1 point(s) boto : 2 point(s)
Write a function surnameFirst(firstname, surname) to take two strings andreturn them in the opposite order; with the surname in capitals and a colon and space inbetween. (e.g. “Michael”, “Palin” would be “PALIN: Michael”) Submit separately as a python file (a & b).
Write a function that converts a phrase into pig Latin. A word is convertedto pig Latin by removing the first character of the word, placing it at theback of the word, and adding the characters “ay” to the word. For example,“hello world” in pig Latin is “ellohay orldway.” Your function can assumethat each word consists of at least two letters and that each word is separatedby one space, with no punctuation marks.
