- Python - need help creating a python program that will sum the digits of a number entered by the user. For example if the user inputs the value 243 the program will output 9 because 2 + 4 + 3 = 9. The program should ask for a single integer from the user, it should then calculate the sum of all the digits of that number and output the result.arrow_forwardI need help with this in Python (with flowchart): Im creating a reverse guessing game. Then to choose a random number from 1 to 100 and the computer program will attempt to guess it, displaying the directions calculated or not. The guess will be displayed and the user will answer if it was correct or not. If correct, the game ends, if not then the computer asks if the guess was too high or too low. Finally inputting an answer and the computer generates a new guess within the proper range. Oh and to make sure the program doesnt guess outside of the ranges produced by the inputs of “too high” and “too low”. The program ending when the user guesses correctly or after the program takes 6 guesses. HELP ASAP!arrow_forwardI need help with this in Python (with flowchart): Im creating a reverse guessing game.
