Hello World

Write a program that greets the user by name, or by saying "Hello, World!" if no name is given.

"Hello, World!" is the traditional first program for beginning programming in a new language.

Note: You can skip this exercise by running:

exercism skip $LANGUAGE hello-world

Specification

The Hello World! program will greet me, the caller.

If I tell the program my name is Alice, it will greet me by saying "Hello, Alice!".

If I neglect to give it my name, it will greet me by saying "Hello, World!"

Test-Driven Development

As programmers mature, they eventually want to test their code.

Here at Exercism we simulate Test-Driven Development (TDD), where you write your tests before writing any functionality. The simulation comes in the form of a pre-written test suite, which will signal that you have solved the problem.

It will also provide you with a safety net to explore other solutions without breaking the functionality.

A typical TDD workflow on Exercism:

1. Run the test file and pick one test that's failing.
2. Write some code to fix the test you picked.
3. Re-run the tests to confirm the test is now passing.
4. Repeat from step 1.
5. Submit your solution (exercism submit /path/to/file)

Instructions

Submissions are encouraged to be general, within reason. Having said that, it's also important not to over-engineer a solution.

It's important to remember that the goal is to make code as expressive and readable as we can. However, solutions to the hello-world exercise will not be reviewed by a person, but by rikki- the robot, who will offer an encouraging word.

Submitting Exercises

Note that, when trying to submit an exercise, make sure the solution is in the exercism/python/<exerciseName> directory.

For example, if you're submitting bob.py for the Bob exercise, the submit command would be something like exercism submit <path_to_exercism_dir>/python/bob/bob.py.

For more detailed information about running tests, code style and linting, please see the help page.
