In a lot of demonstration code I see print statements formatted with brackets in for variables and .format at the end to fill in the variables. Why don't most people just use the variable names in place of the brackets?

Basically, using one of the format method (%s, .format(), f-strings) provides readability for complex substitutions, and automatic conversion to type str. And now with f-strings, they’re actually faster performance.
Post back if you need more help. Good luck!!!

13,561 PointsTo add to Chris' remark about f-strings, I think they are about the best way to do formatting in modern Python. Search on treehouse for the Workshop called "What's new in Python 3.6", for a short description of how to use them.
