In fact, as you can see, class members (attributes as well as methods) are public, being freely accessible from outside the class. Guido Van Rossum &#8211; who developed Python in the early 1990s &#8211; once said, \u201cWe &#8216;re all consenting adults here\u201d justifying the absence of such access restrictions. Then what is a \u2018Pythonic\u2019 way to use getters and setters? The built-in property () function holds the answer.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Python Data Persistence &#8211; Getters\/setters Java class employs getter and setter methods to regulate access to private data members in it.
