Similarly, in Python prior to 3.0, None, True, and False were predefined variables, but not reserved words, but in Python 3.0 they were made into reserved words.
Слично томе, у Пајтону до 3.0, None, True, и False су унапред дефинисане променљиве, али нису резервисане речи, али у Пајтону 3.0 оне су претводене у резервисане речи.
