Python Development Techdegree Student 2,678 PointsWhy 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!

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.

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