if i define a func then write return only what does the func returns?

Answer 1

it will work like break in loops

Answer 2

return calls out a value, usually the value of a property or attribute of the function. but if the parameter is not included, then you are not returning any attribute/property of the function. so it is like returning a null value!!

Answer 3

def func():
return
this? it returns None.

Answer 4

this will output a blank line
