Q1: DIFFERENCE BETWEEN "IS" AND "==" OPERATOR IN PYTHON. IS -->is operator is used to refering the two variables to the same object(Simplt it is identity operator.) == --->is used to compare two objects(simply it is a Equality operator) Q2: TERNARY OPERATOR or CONDITIONAL OPERATOR: Way of writing simple if/else statements in a single line(with 3 orguments). syntax: x= a if (condition) else b if condition is True x=a otherwise x=b Q3: DATA TYPES: 1)int 2)float 3)str(string) 4)complex 5)bool 6)list 7)tuple 8)dict 9)bytearray 10)bytes 11)range..etc Q4: MUTABLE AND IMMUTABLE OBJECTS Mutable: *posible to do modifications once creation of an object. ex: list, dictionary, set . Note: if we try to do modifications we will get an "type error". Immutable: *Imposible to do modifications once creation of an object. ex: Tuple,string,range. Q5: IN PYTHON WHICH OBJECTS ARE MUTABLE AND WHICH OBJECTS ARE IMMUTABLE? Mutable Objects: 1)list 2)dict 3)bytearray 4)set..etc Immutable Objects: 1)int 2)float 3)str(string) 4)complex 5)bool 6)frozenset 7)bytes Note:All fundamental data types are immutable. Q6: **** DIFFERENCE BETWEEN LIST AND TUPLE: **** List: -->List is group of comma seperated values with in square brackets and square brackets are mandatory. * List is an mutable object simly we can do any kind of modifications. ex: l=[10,20,30] --->List riquires more memory space. --->List objects are won't reusable. --->The performance of list is low, i.e, the operation of list object take more time. ---> Comprehension concept is applicable for List . --->List objects are ""unhashable type"" . so we can't store in set and in dict as keys. ex: s={10,20,30,[40,50]} print(S) o/p: TypeError: unhashable type: 'list'. ex: s={[40,50]:"jaya"} print(S) o/p: TypeError: unhashable type: 'list'. --> Unpacking is possible in list but packing is not possible . Tuple: --->Tuple is a group of comma seperated values with in a paranthesis and paranthesis are optional. *Tuple is an immutable object and we can't do any kind of modifications once creation of objects. ex: t=(10,20,30,40,50) t=10,20,30,40,50 ---->Tuple riquire less memory space. ---->Tuple objects are reusable ---> The performance of list is high, i.e, the operation of list object take less time. ---> Comprehension concept is not applicable in Tuple. ---> Tuple objects are """hashable type""" so we can store in set and in dict as keys. ex:s=(10,20,30,[40,50]) print(S) o/p: (10, 20, 30, [40, 50]) --> both packing and unpacking is possible in tuple. Example for memory storage in list and tuple: import sys l=[10,20,30,40,50] t=(10,20,30,40,50) print("The size of List is :",sys.getsizeof(l)) print("The size of Tuple is:",sys.getsizeof(t)) o/p: The size of List is : 88 The size of Tuple is: 80 Example for object reusable in List and python: l1=[10,20,30,40,50,60,70,80,90,100] l2=[10,20,30,40,50,60,70,80,90,100] t1=(10,20,30,40,50,60,70,80,90,100) t2=(10,20,30,40,50,60,70,80,90,100) print(id(l1)) print(id(l2)) print(id(t1)) print(id(t2)) o/p:2869878896000 #list object take different object location. 2869834003584 2869874051648 #tuple object use same object location. 2869874051648 😀😀GIVE LEFT AND RIGHT TO INTERVIEWER IF ASK THESE QUESTIONS....

[@himanshusoni1512]

Try to print on same go like print(id(t1), id(t2)). Each time you hit run, address space changes thus two different addresses you are getting.
