Hello, Again

Problem to Solve

In a file called hello.py in a folder called sentimental-hello, implement a program that prompts a user for their name, and then prints hello, so-and-so, where so-and-so is their provided name, exactly as you did in Problem Set 1. Except that your program this time should be written in Python!

Hints
  • Recall that you can get a str from a user with get_string, which is declared in the cs50 library.
  • Recall that you can print a str with print.
  • Recall that you can create formatted strings in Python by prepending f to a string itself. For example, f"{name}" will substitute (“interpolate”) the value of the variable name where you’ve written {name}.

How to Test

While check50 is available for this problem, you’re encouraged to first test your code on your own for each of the following.

  • Run your program as python hello.py, and wait for a prompt for input. Type in David and press enter. Your program should output hello, David.
  • Run your program as python hello.py, and wait for a prompt for input. Type in Inno and press enter. Your program should output hello, Inno.
  • Run your program as python hello.py, and wait for a prompt for input. Type in Kamryn and press enter. Your program should output hello, Kamryn.
