Static variables are those whose lifetime is the entire run of the application. They exist only in single instance per class and are not initiated.

The variables declared inside the class definition and not inside a method is called a class or static variables.

Example:

class TestClass:
	static_variable = 2

The variable static_variable is accessed as follows,

    TestClass.static_variable

Output

class TestClass:
  #creates a class level variable
  static_variable = 2 

print(TestClass.static_variable)

TestClass.static_variable = 5
print(TestClass.static_variable)

But the above-created static_variable is distinct from any instance-level static_variable, so we could have the below also.

test_obj = TestClass()
test_obj.static_variable = 6

print(TestClass.static_variable, test_obj.static_variable)
