It will then read the file. Once the data is read, it should create an aircraft and then pass the vehicle to the addAircraft method. It should not allow any duplication of records. Be sure to handle all exceptions. o writeFile()-This method accepts a string that represents the name of the file to be written to and then writes the contents of the array to a file.

Your code assumes a twitter feed variable tweets exists, which is a list of strings containing tweets. Each element of this list is a single tweet, stored as a string. For example, tweets may look like: tweets = ["Happy #IlliniFriday!", "It is a pretty campus, isn't it, #illini?", "Diving into the last weekend of winter break like... #ILLINI #JoinTheFight", "Are you wearing your Orange and Blue today, #Illini Nation?"] Your code should produce a sorted list of tuples stored in hashtag_counts, where each tuple looks like (hashtag, count), hashtag is a string and count is an integer. The list should be sorted by count in descending order, and if there are hashtags with identical counts, these should be sorted alphabetically, in ascending order, by hashtag. From the above example, our unsorted hashtag_counts might look like: [('#illini', 2), ('#jointhefight', 1),…arrow_forward

Word Counter (page 608) Write a method that accepts a String object as an argument and returns the number of words it contains. For instance, if the argument is “Four score and seven years ago” the method should return the number 6. Demonstrate the method in a program that asks the user to input a string and then passes it to the method. The number of words in the string should be displayed on the screen.

Morse Code Converter Morse code is a code where each letter of the English alphabet, each digit, and various punctuation characters are represented by a series of dots and dashes. Write a program that asks the user to enter a string, and then converts that string to Morse code and prints on the screen. Use hyphens for dashes and periods for dots. The Morse code table is given in a text file morse.txt. When printing morse code, display eight codes on each line except the last line. Codes should be separated from each other with one space. There should be no extra spaces at the beginning and at the end of the output. Uppercase and lowercase letters are translated the same way.
