What are place holder variables and how do they work? Is it the same as formatting expressions?

I need adequate info on this with examples cuz I'm tired of getting errors as output when running codes 😢

I recommend to read through this. Really, because it is a complicated topic. https://realpython.com/JUMP_LINK__&&__python__&&__JUMP_LINK-string-formatting/ There are many ways to do variable substitution and formatting in strings. My favorite method is the f-string (introduced in python 3.6) in which case you don't even need placeholders, you just embed the variable inside the text like so: w = 'World' print(f'Hello {w}!')
