3.Use a Python string method for each of these: - determine if a string cost contains only numbers. - return how many times the letter 'e' appears in a string called sentence - return the number of characters in a string tmp 4. Exact Output – EXPLAIN WHAT HAPPENED! sentence = "Hi Bye"; tmp = sentence.split(" "); print(tmp) sentence = “hello!" tmp = sentence.split(“ “); print(tmp) 5. Use the Python string method join to - Create a new string that consists of lastName with a comma and a space followed by the firstName firstName = "Sue"; lastName = "Jones"

Write a program that reads a character and a string (an entire line, which may include spaces or tabs), and outputs the number of times the character appears in the string. Hint: use getline(cin, mystring) to read the entire line including spaces. Use mystring.length() to know how many characters. But to avoid a glitch when getline gets an empty string following a cin, do the following sequence: cin >> mychar; /* get character. cin leaves the newline in the input buffer*/ cin.ignore(80,'\n'); /* remove newline from the buffer, which getline would see as empty line*/ cout << "Enter a string: "; //prompt for string getline(cin, mystring); Example program run (the user types only the word "Monday" and the letter "a"): Enter character to count: a Enter a string: Monday count = 1 Example program run: Enter character to count: a Enter a string: Today is Monday count = 2 Example program run: Enter character to count: b Enter a string: Today is Monday count = 0 #include…
In Python, Ask user to enter a line of text as a string, tokenize the string using space characters as delimiters and output only those words ending with the letters ’ed’
Q2) Write a program that reads a one-line sentence as input and then displays the following response: If the sentence ends with a question mark (?) and the input contains an even number of characters, display the word "Yes". If the sentence ends with a question mark and the input contains an odd number of characters, display the word "No". If the sentence ends with an exclamation point (!), display the word "Wow". In all other cases, display the words " you always say "followed by the input string enclosed in quotes" ". Your output should all be on one line. Be sure to note that in the last case, your output must include quotation marks around the echoed input string. In all other cases, there are no quotes in the output. Your program does not have to check the input to see that the user has entered a legitimate sentence. Sample Input#1: Please enter a one line question or statement. How are you? Sample Output#1: Yes Sample Input #2: Please enter a one line…
Write a program to interpolat the string . You can assume that you had two strings and print the results after operation
Write a program which reads string and rewrite it in alphabetical order. For example, the word STRING should be written as GINRST.
Create a program that will accept integer values for month, day, and year and then output the long version of the specified date for example, if month= 11, day=5, and year=2010, output tge string, November 5,2010. If there is any invalid input, display "invalid date" and end the program
Write a python program to let the user enter a string of his own choice. Check whether the given string is a palindrome or not.
(This is a version with input of an exercise from Chapter 1.) Write a program thatinputs two string variables, first and last, which the user should enter with his or her name. First, convert both strings to all lowercase. Your program should then cre-ate a new string that contains the full name in pig latin with the first letter capitalized for the first and last name. Use only the pig latin rule of moving the first letter to theend of the word and adding “ay.” Output the pig latin name to the screen. Use thesubstring and toUpperCase methods to construct the new name.For example, if the user inputs “Walt” for the first name and “Savitch” for thelast name, then the program should create a new string with the text “AltwayAvitchsay” and print it.
Write a program that will take the string "Complication" and concatenate each successive letter, appending it to the existing string until the word is finished, The output should be as follows: C Co Com Comp Compl Compli Complic Complica Complicat Complicati Complicatio Complication Perform the program using a for and a while loop. (Code must be written in python)
Write a program that gets a string containing a person’s first, middle, and last names, and then display their first, middle, and last initials. For example, if the user enters John William Smith the program should display J. W. S.
