The solution mentions ‘numbers’. ‘Number’ is not mentioned in the question or brief. What is ‘number’, what does it do, where does it come from?

I keep seeing…functions? Commands? No idea what’ numbers’ is - but words like this pop up in the solutions in the course - Is it some sort of official command, like the ‘def’ keyword to define functions?

#2

it is mentioned in the instructions:

  • Iterate through lists . Call the looping variable numbers .
  • Iterate through numbers

i think the lesson assumes you are familiar with loops.

Ok, it sounds like I need to recap loops - thank you :blush:
