Why concatenate strings instead of using special characters?

Hi everyone, why would we concatenate the strings (example code 1) instead of using special characters (example code 2)?

print("To: " + to_list)

print("To: {}".format(to_list))

Thanks for the help!

Both methods create the same result, but the concatenation code is a bit more compact.

You could also do this:

print(f"To:  {to_list}")

That's the way I prefer. It's much easier to read and not as prone to errors as concatenation.

I've not seen this before - what does the 'f' represent?

That's an "f-string" (formatted string literal), a relatively new Python feature added in version 3.6.

For more details, see the documentation on Formatted string literals.
