- Notice that all of the data in the inner lists are represented as strings. You are to write the function convert_data, which should make modifications to the inner lists according to the following rules: If and only if a string represents a whole number (ex: '3' or '3.0'), convert the string to an int. If and only if a string represents a number that is not a whole number (ex: '3.14'), convert the string to a float. Otherwise, leave the string as a str.HINT: The provided helper function is_number may be used (attached image). QUESTION: Complete the docstring below.def convert_data(data: List[list]) -> None: """Convert each string in data to an int if and only if it represents a whole number, and a float if and only if it represents a number that is not a whole number. >>> d = [['abc', '123', '45.6', 'car', 'Bike']] >>> convert_data(d) >>> d [['abc', 123, 45.6, 'car', 'Bike']] >>> d = [['ab2'], ['-123'], ['BIKES', '3.2'],…arrow_forwardin pythonString full_string is read from input.

A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes in word pairs that consist of a name and a phone number (both strings), separated by a comma. That list is followed by a name, and your program should output the phone number associated with that name. Assume the search name is always in the list. Ex: If the input is: Joe,123-5432 Linda,983-4123 Frank,867-5309 Frank the output is: 867-5309arrow_forward

Write a version of the selection sort algorithm presented in the unit, which is usedto search a list of strings.2. Write a version of the binary search algorithm presented in the unit, which isused to search a list of strings. (Use the selection sort that you designed aboveto sort the list of strings.)3. Create a test program that primes the list with a set of strings, sorts the list, andthen prompts the user to enter a search string. Your program should then searchthe list using your binary search algorithm to determine if the string is in the list.Allow the user to continue to search for strings until they choose to exit theprogramarrow_forward
