How to create a list of object in Python class
We can create list of object in Python by appending class instances to list. By this, every index in the list can point to instance attributes and methods of the class and can access them. If you observe it closely, a list of objects behaves like an array of structures in C. Let’s try to understand it better with the help of examples.
Example #1:
# Python3 code here creating classclass geeks: def __init__(self, name, roll): self.name = name self.roll = roll # creating list list = [] # appending instances to list list.append( geeks('Akash', 2) )list.append( geeks('Deependra', 40) )list.append( geeks('Reaper', 44) ) for obj in list: print( obj.name, obj.roll, sep =' ' ) # We can also access instances attributes# as list[0].name, list[0].roll and so on. |
Output:
Akash 2 Deependra 40 Reaper 44
Example #2:
# Python3 code here for creating classclass geeks: def __init__(self, x, y): self.x = x self.y = y def Sum(self): print( self.x + self.y ) # creating list list = [] # appending instances to list list.append( geeks(2, 3) )list.append( geeks(12, 13) )list.append( geeks(22, 33) ) for obj in list: # calling method obj.Sum() # We can also access instances method# as list[0].Sum() , list[1].Sum() and so on. |
Output:
5 25 55
