Use python Exercise 3. Colored polygons. Write a function cpolygon(n, size) that takes in two arguments: n (the number of sides of a polygon), and size (its side length in pixels). The function draws an n-sided polygon with alternating black and red colors. Hint: The function turtle.color(col) changes the color of the pen to col, which is a string specifying the desired color (black, red, etc.).

please code in python MCQ are a very popular form of assessment because they can be automatically graded…and the students can choose an answer at random if they don’t know.The goal of this exercise is to write a function scoreMCQ(attempt, correct), where attempt is a string that contains the answers of the student and correct is a string with the correct answers.The function should return the number of correct answers.Check first that both strings have the same length, otherwise raise an exception.If both strings are empty the score should be 0 of course.To test your code, you can copy paste the following assert statements as your main function:assert(scoreMCQ("","")==0), "First test failed"assert(scoreMCQ("TFTF","TTTT")==2), "Second test failed"assert(scoreMCQ("TTTT","TTTT")==4), "Third test failed"assert(scoreMCQ("CCCC","ABCD")==1), "Fourth test failed"print("All tests succesfull")
Ex. 8.4) The following functions are all intended to check whether a string contains any lowercase letters, but at least some of them are wrong. For each function, describe what the function actually does (assuming that the parameter is a string).
Create a function that determines whether each seat can "see" the front-stage. A number can "see" the front-stage if it is strictly greater than the number before it. Everyone can see the front-stage in the example below: # FRONT STAGE [[1, 2, 3, 2, 1, 1], [2, 4, 4, 3, 2, 2], [5, 5, 5, 5, 4, 4], [6, 6, 7, 6, 5, 5]] # Starting from the left, the 6 > 5 > 2 > 1, so all numbe # 6 > 5 > 4 > 2 - so all numbers can see, etc. Not everyone can see the front-stage in the example below: # FRONT STAGE [[1, 2, 3, 2, 1, 1], [2, 4, 4, 3, 2, 2], [5, 5, 5, 10, 4, 4], [6, 6, 7, 6, 5, 5]] # The 10 is directly in front of the 6 and blocking its v
Complete the rotate_text() function that takes 2 parameters, a string data and an integer n. If n is positive, then the function will shift all the characters in data forward by n positions, with characters at the end of the string being moved to the start of the string. If n is 0 then the text remains the same. For example: rotate_text('abcde', rotate_text('abcde', rotate_text('abcde', 1) would return the string 'eabcd' 3) would return the string 'cdeab' 5) would return the string 'abcde' rotate_text('abcde', 6) would return the string 'eabcd' ... and so on. If n is negative, then the function will shift the characters in data backward by n positions, with characters at the start of the string being moved to the end of the string. For example: rotate text('abcde', -1) would return the string 'bcdea'
python Write a function named first_medium_last that accepts a single string as its parameter representing a person's first, middle and last name. The function should return the person's first name, followed by their middle initial, followed by their last name. For example, the call first_medium_last("Bartholomew JoJo Simpson") should return "Bartholomew J. Simpson". You may assume that the argument consists of exactly three words separated by single spaces. Note that there should be a period (dot) after the middle initial.
in javas Write a function that accepts string as its argument. The function should count the number of vowels appearing in the string and return that number. Write another function that accepts a string as its argument. This function should count the number of consonants appearing in the string and return that number. Demonstrate these two functions in a program that performs the following steps: The user is asked to enter a string. The program displays the following menu: A) Count the number of vowels in the string B) Count the number of consonants in the string C) Count both the vowels and consonants in the string D) Enter another string E) Exit the program The program performs the operation selected by the user and repeats until the user selects E to exit the program.
Please do not give solution in image format thanku Write a python program that does the following. Make sure it works and can interface with the user in PyCharm. Write a function word count that will take a sentence (string) and return to you the number of words in the sentence. Show it works by calling it with “Cinderella must get to the ball without her slippers.” (Answer should be 9)
A palindrome is a word, phrase, number, or other sequence of characters that reads the same forward and backward, disregarding spaces, punctuation, and capitalization. Write a function isPalindrome that takes in a string s and returns a boolean value indicating whether s is a palindrome. Example: Input: s = "racecar" Output: true Input: s = "Hello" Output: false Input: s = "A man, a plan, a canal, Panama" Output: true Input: s = "12321" Output: true Note: The input string may contain spaces, punctuation, and capitalization, but they should be disregarded while checking for palindromes. An empty string is considered a palindrome.
