By default all numbers, methods, variables of the class are public in the Python programming language; we can access them outside of the class using the object name.

Consider the given example:

Here, we have two variables name and age both are initializing with default values ("XYZ" and 0) while declaring the object using __init__ method.

Later, in the program, outside of the class definition – we are assigning some values ("Amit" and 21) to name and age, that is possible only if variables are public.

Example:

# Python example for public variables 
class person:
	def __init__(self):
		# default values
		self.name = "XYZ"
		self.age = 0

	def printValues(self):
		print "Name: ",self.name 
		print "Age : ",self.age

# Main code 
# declare object 
p = person()
# print
p.printValues();

# since variables are public by default 
# we can access them directly here 
p.name = "Amit"
p.age = 21
# print
p.printValues ();

Output

Name:  XYZ
Age :  0
Name:  Amit
Age :  21
