Part I: Validate Street Addresses (10 points) Write a function street.addresses(),which takes a single argument addresses, which is a list of strings. The function analyzes each string, and, if the string's format matches the pattern of a valid street address as described below, the function appends the string's index in addresses into a returned list. A validly formatted address is defined by the following components, in the given order: 1. one or more digits 2. exactly one space 3. an uppercase letter, followed by any combination of uppercase letters, lowercase letters and spaces exactly one space 5. the word Street', 'Road' or ' Path', capitalized exactly as given 6. optionally, the following text: a. exactly one space b. the string 'Apt. ', capitalized exactly as given c. exactly one space d. exactly one uppercase letter Examples of validly formatted addresses are ' 58 Gnarled Oak Street' and '173 East Main Road Apt. Q' Suppose the following list were passed as addresses: '21 Main Street', '12 Main Drive', '5 Elm Apt. E,'6 Elm Path Apt. 5'] The function would return [0, 31 because only the first and last strings in this example match the pattern defined above
