is instance in python code example

Example 1: isinstance python

isinstance(object, classinfo)

# if classinfo is a tuple of type objects (or recursively, other such tuples), return True
# if object is an instance of any of the types. If classinfo is not a type or tuple of types
# and such tuples, a TypeError exception is raised.

Example 2: is instance string python

isinstance(x, int)
isinstance(s, str)

Example 3: instance method in python

# Instance Method Example in Python 
class Student:
    
    def __init__(self, a, b):
        self.a = a
        self.b = b 
    
    def avg(self):
        return (self.a + self.b) / 2

s1 = Student(10, 20)
print( s1.avg() )

Example 4: python instance Object

x.counter = 1
while x.counter < 10:
    x.counter = x.counter * 2
print(x.counter)
del x.counter
