Why Can't I call base class function for my derived class object?

[AmirAB]

Hi experts!
Any idea if I am making an error in my code as I am not able to understand Why Can't I call the the base class function for my derived class object?

class My_base_class():
    def __init__(self):
        print("This is __init__function of Base Class")
    def base_class_func1(self):
        print("my base class function")
    def base_class_func2(self):
        print("my base class function # 2")     
       
class My_derived_class():
    def __init__(self):
        My_base_class.__init__(self)
        print("I am inside my __init__function of my Drived Class")
    def base_class_func1(self):
        print("my base class function")    
    def derived_class_func1(self):
        print("I am inside my derived class function 01")
        
my_inherit=My_derived_class()
my_inherit.base_class_func2()# I get error while I call function of base class.

Error:'My_derived_class' object has no attribute 'base_class_func2'
