Hello World in Scheme

Our first program will print the classic “hello world” message. Here’s the full source code.

if __name__ == "__main__":
    print("hello world")

To run the program, save the code in a file named hello_world.py and use the python command.

$ python hello_world.py
hello world

Sometimes we’ll want to create an executable for our Python programs. We can do this using tools like pyinstaller.

First, install pyinstaller if you haven’t already:

$ pip install pyinstaller

Then create an executable:

$ pyinstaller --onefile hello_world.py
$ ls dist/
hello_world

We can then execute the built binary directly.

$ ./dist/hello_world
hello world

Now that we can run and build basic Python programs, let’s learn more about the language.
