1. What is _init_ in python? it's an init() method in every call defined in Python.. to initialize like constructor like in java. class Employee: def __init__(self, name, age,salary):     //self is an instance or an object of a class. In Python, this is explicitly included as the first parameter. self.name = name self.age = age self.salary = 20000 E1 = Employee("XYZ", 23, 20000) # E1 is the instance of class Employee. #__init__ allocates memory for E1.  print(E1.name) print(E1.age) print(E1.salary) ----------------------------------------------------------------------------------------- 2. Lambda function a = lambda x,y : x+y print(a(5, 6)) b = lambda x,y,z : (x+z)/y print(b(9,3,6)) ----------------------------------------------------------------------------------------- 3. What does [::-1] do? A. It reverse's the array. import array as arr My_Array=arr.array('i',[1,2,3,4,5]) My_Array[::-1] Output: array(‘i’, [5, 4, 3, 2, ...
