How to use a returned value?

[buran]

when declaring the returned values back to the funtion itself

not sure what you mean by this

on the RHS is the function call and the function returns tuple with 5 values
on the LHS are 5 names and you unpack the tuple into these (i.e. assign each element from tuple returned by the function to individual name)

probably confusion comes because the names used within the function scope (i.e. the local scope) are same as the names in global scope. However these are names with different scopes
