- String replacement is read from input. Then, sentence is read from input. If replacement is in sentence, then: Output 'Located at index: ' followed by the index of the last occurrence. Create a string from sentence with the first two occurrences of replacement replaced by '5' and output sentence on a newline.Revorse the vewels def reverse_vowels(text): Given a text string, create and return a new string constructed by finding all its vowels (for simplicity, in this problem vowels are the letters found in the string 'aeiouAEIOU') and reversing their order, while keeping all other characters exactly as they were in their original positions. However, to make the result look prettier, the capitalization of each moved vowel must be the same as that of the vowel that was originally in the target position. For example, reversing the vowels of 'Ilkka' should produce 'Alkki' instead of 'alkkI'. Applying this operation to random English sentences seems to occasionally give them a curious pseudo-Mediterranean vibe. Along with many possible other ways to perform this square dance, one straightforward way to reverse the vowels starts with collecting all vowels of text into a separate list, and initializing the result to an empty string. After that, iterate through all positions of the original text.…Revorse the vewels def reverse_vowels(text): Given a text string, create and return a new string constructed by finding all its vowels (for simplicity, in this problem vowels are the letters found in the string 'aeiouAEIOU') and reversing their order, while keeping all other characters exactly as they were in their original positions.

- Q4: Colouring Book Having spent the last couple of hours grading assignments, I decide it’s time for a break. I take out my favourite colouring book, turn to a random page I haven’t coloured in yet, and lay it on my desk. I then take out all my n crayons and line them up on the desk (it’s a very long desk). The colour of the ith crayon is a string c[i] (e.g. "blue"). Many of the crayons have the same colour. In fact, no matter how many crayons I have, there are at most 30 distinct colours amongst them. To start colouring, I always take a sublist (see Q1 for a definition) of the crayons laid on the desk and put away the rest (too many options can be overwhelming and can lead to indecision). I take a look at the line art in front of me and wonder, “How many different colours do I need to make this look great? One? Two? Maybe three?”. Now you understand my dilemma and are fully aware of my indecision. You kindly decide to help me out by telling me for every number k, if I were to use…StretchWith2Vowels Specification: Read sentences from the user until * is entered. Show the number of words in each sentence that contain a stretch of non-z characters with exactly 2 vowels. A stretch starts from the start of the word or after a 'z'. A stretch terminates just before another 'z' or at the end of the word. Examples: 1. Matching words: zoo, azozooza, GONZALEZ 2. Non-matching words: ozo, azoooza The sentences contain no punctuation, the words are separated by one or more spaces, and the characters may be upper or lower case. Keep reading sentences until the user enters "*". Sample I/O: Sentence: azoooza azooza zoo azo0 Matching words = 3 Sentence: GONZALEZ passes the ball to VAZQUEZ Matching words = 3 Sentence: azozototzeti Matching words = 1 Sentence: * DoneColouring Book Having spent the last couple of hours grading assignments, I decide it’s time for a break.

- Allow student to insert one arbitrary string. Save the letters of the string into a list. Design and perform the following tasks and display your results: • Summarizing letters in a string. Write a function that receives a string and returns a list of tuples containing the unique letters and their frequencies in the string. Test your function and display each letter with its frequency. Your function should ignore case sensitivity (that is, 'a' and 'A' are the same) and ignore spaces and punctuation. When done, write a statement that says whether the string has all the letters of the alphabet. • Present descriptive statistics and graphs about the string data. • Sorting letters in different order and removing duplicates • Write a code that produces anagrams of a given string. An anagram of a string is another string formed by rearranging the letters in the first. program must accept inputs from a user, performs an operation using a userdefined function which will accept parameters and…Complete the analyze_text() function that takes a single string parameter - text. You can assume that the parameter string will have a length of at least 1. The function returns a list with 2 items, both of them tuples. The first tuple contains the unique vowels found in the parameter text, sorted in alphabetical order. The second tuple contains the unique consonants found in the parameter text, sorted in alphabetical order. In English, vowels are the letters "A", "E", "I", "O", and "U". Consonants are letters that are not vowels. Note that uppercase and lowercase letters should count as the same letter - an "A" and an "a" would both count as an "a". Some examples of the function being called are shown below. For example: Test text = "Hello world!" print("Text analysis:", analyze_text (text)) text = "Hello world!" text_analysis = analyze_text (text) print (type (text_analysis)) print (type (text_analysis[0])) print (type (text_analysis[1])) text = "I think, therefore I am." print("Text…import numpy as np import torch import matplotlib.pyplot as plt Quiz Preparation Question 1.

Example: alphabet_soup(“hello") - ehllo alphabet_soup(“hacker") – acehkrpublic static String pancakeScramble(String text) This nifty little problem is taken from the excellent Wolfram Challenges problem site where you can also see examples of what the result should be for various arguments. Given a text string, construct a new string by reversing its first two characters, then reversing the first three characters of that, and so on, until the last round where you reverse your entire current string• get_tokens_from_equation(line): Takes one string as input that contains any combination of digits from 0-9 and the following mathematical symbols: + - x / = ^ (O The string does not have to correspond to a valid mathematical equation. For example, '4-3=0' and '4xx5=(8' could be valid inputs to this function. The function will translate the string into a list of tokens. A token is a single non-negative number (of any length) or a single mathematical symbol. Numbers should be added to the list as integers, and symbols as strings. The tokens in the list should be in the same order as the numbers/symbols appear in the string. For example, given the string '52-2=50', the function should return the list [52, '-', 50]. >>> get_tokens_from_equation('4=3') [4, '=', 3] >>> get_tokens_from_equation('6-5=15^4/2') [6, '-', 5, '=', 15, '^', 4, '/', 2] >>> get_tokens_from_equation('288/24x6=18x13x8') [288, '/', 24, 'x', 6, '=', 18, 'x', 13, 'x', 8]
