27.String slice Take the following Python code that stores a string: str = 'X-DSPAM-Confidence[0.8475]' Use find and string slicing to extract the portion of the string inside the unique square brackets [] and then use the float function to convert the extracted string into a floating point number. Your code should be able to automatically handle different content strings in the same format. Don't print a fixed number only for this particular input, or count

Write a program to read a gene structure and search string. Use strstr Function to determine the occurrence of string in the sequence. Also display remaining sequence every time. Need source code and explanation please.
Create a function that returns the characters from a list or string ron odd or even positions, depending on the specifiers. The specifier will be "odd" for items on odd positions (1, 3, 5, ...) and "even" for items on even positions (2, 4, 6, ...). Examples char_at_pos([2, 4, 6, 8, 10], "even") [4, 8] # 4 & 8 occupy the 2nd & 4th positions - char_at_pos ("EDABIT", "odd") "EAI" # "E", "A" and "I" occupy the 1st, 3rd and 5th positions char_at_pos(["A", "R", "B", "I", "T", "R", "A", "R", "I", "L",
Question 2: Write a function that takes a string as its only argument and returns a sorted list of characters used in the string. The resulting list should only contain lower case letters and each letter should exist only once. Also, the resulting list shouldn't contain any spaces or punctuation marks, such as ",;.!?". For example, strletters ("We are, the Champions!") returns ['a', 'c', 'e', 'h', 'i', 'm', 'n', 'o', 'p', 'r', 's', 't', 'w'] def strletters(istr):
plase skip it if you dont know the correct answer i need it urgent. Will doewnvote in case of wrong or copied answers from chegg or bartleby! A regular expression (shortened as regex or regexp; also referred to as rational expression) is a sequence of characters that specifies a search pattern. Usually such patterns are used by string-searching algorithms for "find" or "find and replace" operations on strings, or for input validation. using regex create a python program to verify the string having each word start from 'p'? It should return True otherwise false.

exercise5.py 1 Your code goes here... Guide Collapse Strings -> Coding Exercises - Strings Exercise 5 Exercise 5 Problem Write a program that captures input from the user. Then, swap the letters two at a time in the string. The first two characters change places, the third and fourth characters change places, etc. Assume that the user will only input strings with an even number of characters. Important, do not put a prompt when asking for user input. Just use input(). Adding a prompt will cause your program to not pass the tests. Expected Output • If the user inputs home, then the output is ohem . If the user inputs cars then the output is acer Code Visualizer TRY IT Reminder, do not put a prompt when collecting user input. Just use input() Check It! (1 left) TTT
PYTHON Complete the function below, which takes two arguments: data: a list of tweets search_words: a list of search phrases The function should, for each tweet in data, check whether that tweet uses any of the words in the list search_words. If it does, we keep the tweet. If it does not, we ignore the tweet. data = ['ZOOM earnings for Q1 are up 5%', 'Subscriptions at ZOOM have risen to all-time highs, boosting sales', "Got a new Mazda, ZOOM ZOOM Y'ALL!", 'I hate getting up at 8am FOR A STUPID ZOOM MEETING', 'ZOOM execs hint at a decline in earnings following a capital expansion program'] Hint: Consider the example_function below. It takes a list of numbers in numbers and keeps only those that appear in search_numbers. def example_function(numbers, search_numbers): keep = [] for number in numbers: if number in search_numbers(): keep.append(number) return keep def search_words(data, search_words):
The function count_contains_og in python takes a list of strings and returns how many strings in the list contain 'og' / 'OG' / 'oG' / 'Og' (check for 'og', ignoring case). Hint: Use the sequence membership operator in to help you check for 'og' in the individual strings. Create a lower-cased version of the string (lower), then use the in operator. For example: Test Result str_list = ['cat', 'dog', 'FROG', 'monkey'] print(count_contains_og(str_list)) 2 strlist = ["X", "x"] print(count_contains_og(strlist)) 0 list_of_one_og = ["Doggie"] print(count_contains_og(list_of_one_og)) 1
Problem 3: Write a function that takes in a string as input and returns a list of the unique characters used in the string. Punctuation should not be counted as a unique character. For our purposes you may consider the following characters as punctuation:.,;:?!"'- Your list should return all letters as lower case and sorted. So for example if the input is days are here again! 'your function should return the list ['a''d','e','g','h','i','n','p','r','s','y'l Нарру In [ ]: 1 # write your code here 2 # you may add more cells as needed
[Python] Write a function called “add_spaces” that takes in an argument called “initial_string”. initial_string will always be a non empty string. The function should return the same string but with an added space in between all of the letters. If there are already spaces in the initial_string passed in, you should not add an extra space in between those spaces.
Complete main() to read dates from input, one date per line. Each date's format must be as follows: March 1, 1990. Any date not following that format is incorrect and should be ignored. Use the substr() function to parse the string and extract the date. The input ends with -1 on a line alone. Output each correct date as: 3/1/1990. #include <iostream>#include <string> using namespace std; int DateParser(string month) { int monthInt = 0; if (month == "January") monthInt = 1; else if (month == "February") monthInt = 2; else if (month == "March") monthInt = 3; else if (month == "April") monthInt = 4; else if (month == "May") monthInt = 5; else if (month == "June") monthInt = 6; else if (month == "July") monthInt = 7; else if (month == "August") monthInt = 8; else if (month == "September") monthInt = 9; else if (month == "October") monthInt = 10; else if (month ==…
