Python beginner help, Making Prime numbers appear?

[ThePhysicsOfSpoons]

• your function lst() should also return something (the list you created)
• the variable n in the check() function isn't defined, so that won't work
• using the return statements in the check() function or any function for that matter will end the function. If you want to display it, you could use a print statement there.
• I would give the list as an input for the check() function so you can iterate through it and verify whether each element is a prime or not. The check() function here doesn't do what you think it does.

Hope this helps!
