return_stmt: "return" [condition_list]
return
may only occur syntactically nested in a function
definition, not within a nested class definition.
If a condition list is present, it is evaluated, else None
is substituted.
return
leaves the current function call with the condition
list (or None
) as return value.
When return
passes control out of a try
statement
with a finally
clause, that finally clause is executed
before really leaving the function.
