Python Introducing Lists Using Lists Split and Join

Using "string" + variable or "string", variable?

I noticed all of the following prints as I expect.

print("To: ", too_line) print("CC: " + cc_line) print("Hello", "Earth")

Is there any reason to not use the "," to separate two or more things to join? I think I saw it in an example and felt it was much cleaner code. Will using that be problematic in the future or is it another method one can choose to use in their code?

Hello Phillip, I may be wrong but I am pretty certain that the comma is just another formatting style you can use in your prints if you prefer.

If you separate two elements with a comma, Python will automatically add a space between them, like so:
print("Hello", "world.") --> Hello world.

If you instead use + to separate them, Python will concatenate the two without an added space:
print("Hello" + "world.") --> Helloworld.
