Write a program in python with a loop to compute and print the powers of 2, for powers 0 to 20 inclusive.

Write a python program using a while or for loop that takes in a line of text as input, and outputs that line of text in reverse. The program repeats, ending when the user enters "Done", "done", or "d" for the line of text.

write a snippet of java code that contains a for loop to compute 1 + 9 + 25 +...+81, i.e. the for loop should find the sum of the squares of the odd integers that are less than 10. Note that by a snippet of code, we mean you do not have to write an entire program - only those statements essential to finding the sum.

write a loop that reads positive integers from standard input and that terminates when it reads an integer that is not positive. After the loop terminates, it prints out, ona line by itself, the sum of all even integers read. a while loop and python is required to do the question

Write a Python program that will ask the user to input a word, will return the first letter of the input word, and ask the user to put another word, and so on, in the form of a loop. If the user chooses to stop, he or she should input the integer "0" for the loop to stop.

Write Java code to print the odd numbers from 1 to 100: (a) using for loop. (b) using while loop. (c) using do-wile

Use Python Write a function, say_spam(n); it takes an integer parameter n and prints "Spam!" n times in response. You should assume n > 0 for this function. Hint: Use a simple for loop with a print statement in the body of the loop. For example: Test Input Result say_spam(1) Spam! say_spam(2) say_hello(3) Spam! Spam! say_spam(5) Spam! Spam! Spam! Spam! Spam!
