Create a function that determines how many number pairs are embedded in a space-separated string. The first numeric value in the space-separated string represents the count of the numbers, thus, excluded in the pairings. Examples number_pairs("7 1 2 1 2 1 3 2″) → 2 // (1, 1), (2, 2) number_pairs("9 10 20 20 10 10 30 50 10 20") - 3 // (10, 10), (20, 20), (10, 10) number_pairs("4 2 3 4 1") 0 // Although two 4's are present, the first one is discounted.

Analyze the following statements carefully and decide whether the statements that appear after the code are true or false.

Using Python write a string-comparison function named strNcompare that compares up to n characters of a string s1 with the other string s2. The function must return 0, -1, or 1 if the first n-character portion of s1 is equal to, less than, or greater than the corresponding first n-character portion of s2, respectively. (1) You must use the following function definition: def strNcompare(s1, s2, n): (2) String comparison must be case-insensitive. For example, the strNcompare function must return 0 for the s1 value of ‘tommy’ and the s2 value of ‘TOMMY’. (3) You should not use a loop such as the while loop and the for loop inside the strNcompare function.    Then write a Python program that receives two words and the number of characters for comparison, calls the strNcompare function, and then shows the result. Your program keeps doing this until the user enters the value of -1.     Your program displays the message ‘String comparison [1(play), -1(quit)]: ’ and receives the value 1 or -1…

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 'e'? It should return True otherwise false.
