Why use interpolation?

Lets say I defined a variable combination as "Hello". What is the difference between printing the variable in these two ways? Is it the same thing but written in different ways or is there an advantage in using one over another?

print("(combination)")

print(combination)

Interpolation allows you to easily print out a string which maybe contains more than one variable as well and some additional text which you are inputting into the actual print method itself.

You can also concatenate the strings and variables to achieve the same thing but often if interpolation is available it will be a lot easier to read and look nicer in your code.
