please code in python A tweet is a string that is between 1 and 280 characters long (inclusive). A username is a string of letters and/or digits that is between 1 and 14 characters long (inclusive). A username is mentioned in a tweet by including @username in the tweet (notice the username does not include the @ symbol). A retweet is way to share another user's tweet, and can be identified by the string RT, followed by the original username who tweeted it. Your job is to fill in the function count_retweets_by_username so that it returns a frequency dictionary that indicates how many times each retweeted username was retweeted.tweets = ["This is great! RT @fakeuser: Can you believe this?", "It's the refs!

JAVA PPROGRAM ASAP Please create this program ASAP BECAUSE IT IS MY LAB ASSIGNMENT #2 so it passes all the test cases. The program must pass the test case when uploaded to Hypergrade. Chapter 9. PC #8. 8. Sum of Numbers in a String (page 610) Write a program that asks the user to enter a series of numbers separated by commas. Here are two examples of valid input: 7,9,10,2,18,6 8.777,10.9,11,2.2,-18,6 The program should calculate and display the sum of all the numbers. Input Validation 1. Make sure the string only contains numbers and commas (valid symbols are '0'-'9', '-', '.', and ','). 2. If the string is empty, a messages should be displayed, saying that the string is empty. Test Case 1 Enter a series of numbers separated only by commas or type QUIT to exit:\n7,9,10,2,18,6ENTERThe sum of those numbers is 52.00\nEnter a series of numbers separated only by commas or type QUIT to exit:\nENTEREmpty string.\nEnter a series of numbers separated only by…
Name format: You must use String object and not StringBuffer or StringBuilder. Many documents use a specific format for a person's name. Write a program that take one Line as an input. Example: Scanner input = new Scanner(System.in); System.out.println(“Enter firstName middleName lastName separated by at least one blank, It may have more than one blank separating firstName middleName lastName."); Input sample : Pat Silly Doe || Note these are separated by at least one blank. String line = input.nextLine() Ex: If the input is: Pat Silly Doe the output is: Doe, P.S. If the input has the form: firstName lastName the output is: lastName, firstInitial. Ex: If the input is: Julia Clark the output is: Clark, J. Please submit the .java source file and the sample run in a text file. Thanks
Word Separator Create an application that accepts as input a sentence in which all the words are run together but the first character of each word is uppercase. Convert the sentence to a string in which the words are separated by spaces and only the first word starts with an uppercase letter. For example, the string "StopAndSmellTheRoses." would be converted to "Stop and smell the roses."

2. The Integer.parseInt () method requires a String argument, but fails if the String cannot be converted to an integer. Write an application in which you try to parse a String that does not represent an integer value. Catch the Number FormatException that is thrown, and then display an appropriate error message.

def swap_text(text): Backstory: Luffy wants to organize a surprise party for his friend Zoro and he wants to send a message to his friends, but he wants to encrypt the message so that Zoro cannot easily read it. The message is encrypted by exchanging pairs of characters. Description: This function gets a text (string) and creates a new text by swapping each pair of characters, and returns a string with the modified text. For example, suppose the text has 6 characters, then it swaps the first with the second, the third with the fourth and the fifth with the sixth character. Parameters: text is a string (its length could be 0)Return value: A string that is generated by swapping pairs of characters. Note that if the Examples: swap_text ("hello") swap_text ("Party for Zoro!") swap_text ("") def which_day(numbers): → 'ehllo'→ 'aPtr yof roZor!' → '' length of the text is odd, the last character remains in the same position.
