Question

import re WNP # All questions MUST be answered in ONE line and MUST use the re module. # 6 11 Question 1 Given an input phone number, return only the numeric characters in the string. Ex: | >>> print (phone_number_cleaner('(678)911-9111')) 6789119111 14 15 def phone_number_cleaner(parameter): pass 19 Question 2 Return the longest possible string from the input that starts with 'b' and ends with 'a' (case sensitive). There should be zero or more of any character between the 'b' and 'a'. Ex: >>> print(greedy_search('banana')) banana 27 28 29 def greedy_search(parameter): pass 30 32 33 34 35 Question 3 Return the shortest possible string from the input that starts with 'b' and ends with 'a' (case sensitive). Ex: >>> print(greedy_search('banana')) ba 37 38 39 def non_greedy_search(parameter): pass 40 42 43 44 45 Question 4 Return a tuple of the starting and ending indices of the first sequence of numbers in the input string Ex: >>> print(number_indices ("My phone number is 911")) (19, 22) def number_indices (parameter): pass 52 54 Question 5 Given an input string, return a string with only letters and spaces included from the input 56
