Difference between methods and attributes in python

Question

I am learning python and doing an exercise about classes. It tells me to add nd attribute to my class and a method to my class. I always thought these were the same thing un

Answer 1

class example:
    global a
    # a=0

    def __init__(self,x,y):
        self.fname=x
        self.lname=y
    def show(self):
        return "first name: {} & Last name: {}".format(self.fname,self.lname)

obj1=example('reyan','ishtiaq')
obj2=example('ishtiaq','reyan')

print('method associated with obj1: '+ obj1.show())
print('method associated with obj2: '+ obj2.show())

obj1.a=20
obj2.a=30

print(obj1.a)
print(obj2.a)

output: method associated with obj1: first name: reyan & Last name: ishtiaq................ method associated with obj2: first name: ishtiaq & Last name: reyan................ 20 30
