What does return do? Nothing is ever returned

Question

I have been learning Python for some days now. However, I do not understand return. I have read several explanations from my textbooks and online; they don\'t help!

Answer 1

You either need to add a print or write the whole thing into the interactive interpreter to see the return value.

return makes it possible to get some output/result out of a function. To this value later in the code you have to assign it to a variable:

a = sqrt(25)
