What is meant by "return True"

How to assign a boolean value to the return? I want to do something like... return true

strlen.py 
def just_right(yourString) :
  ysl = len(yourString)
  if ysl < 5 :
    return "Your string is too short"
  elif ysl > 5 :
    return "Your string is too long"
  else :
    return

def just_right(string):
  if len(string) < 5:
    return "Your string is too short"
  elif len(string) > 5:
    return "Your string is too long"
  else:
    return True

#The "return" statement
**********************
#return_stmt ::= "return" [expression_list]
#"return" may only occur syntactically nested in a function definition,
#not within a nested class definition.
#If an expression list is present, it is evaluated, else "None" is
#substituted.
#"return" leaves the current function call with the expression 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.
#In a generator function, the "return" statement indicates that the
#generator is done and will cause "StopIteration" to be raised. The
#returned value (if any) is used as an argument to construct
#"StopIteration" and becomes the "StopIteration.value" attribute.
#In an asynchronous generator function, an empty "return" statement
#indicates that the asynchronous generator is done and will cause
#"StopAsyncIteration" to be raised.  A non-empty "return" statement is
#a syntax error in an asynchronous generator function.

return True or False is a way to see if the function was succesful or not. fx 

def checkName(name):
    if name == "John":
        return True
    else:
        return False
