super()

super() returns access the base class methods

By using super() we need not use the name of the base class explicitly.
It is useful in multiple inheritance

Example with inheritance

class animals():
    home='Jungle' #class attribute
#instance attributes
    def __init__(self,name,height):
        self.name= name
        self.height=height
    def legs(self):
        print("has four legs")
    
class wild(animals):
    def __init__(self,name,weight):
        self.name=name
        self.weight=weight
        #animals.__init__(self,name,5)
        super().__init__(name,5)   
    
tiger=wild('Tom',3) # object is created. 
print(tiger.weight) # 3
print(tiger.height) # 5   
tiger.legs()        # has four legs
In above code by using super() we can access the methods of the base class animals(). While not using super() we can access the methods of parent class animals() by using the line animals.__init__(self,name,5).

By using super() we can avoid explicit use of base class name. The advantage is while using multilevel inheritance.

Multiple inheritance

class animals():
    home='Jungle' #class attribute
#instance attributes
    def __init__(self):
        self.name= 'Alex'
        self.height=2
    def legs(self):
        print("has four legs")
class carnivores(animals):
    def __init__(self):
        self.food='flseh'
        super().__init__()
        
class wild(carnivores):
    def __init__(self):
        self.weight=5
        #animals.__init__(self,name,5)
        super().__init__()   
    
tiger=wild()    # object is created. 
print(tiger.weight) # 3
print(tiger.food)   # flesh 
print(tiger.name)   # Alex
print(tiger.height) # 2 
tiger.legs()        # has four legs
