Question: What do you mean by membership operators in Python?
Answer: Membership operators are used to check whether a value/variable exists in the sequence like string, list, tuple etc. These operators return True or False as per conditions met.
Membership operators are of two types as:
(i) in operator
(ii) not in operator
Question: Find the output of following code?
t = (‘A’, ‘R’, ‘I’, ‘H’, ‘A’, ‘N’, ‘T’)

Answer: Output
A
R
I
H
A
N
T
Question: What will be the output of following code?
tuple1=(1,2,3,4,5)
tuple2=(6,7,8,9)
for item in tuple1:
if item in tuple2:
print(“overlapping”)
else:
print(“not overlapping”)
Answer: Output not overlapping
Question: Prove with the help of an example that the variable is rebuilt in case of immutable data types.
Answer: When a variable is assigned to the immutable data type, the value of the variable cannot be changed in place.
Therefore, if we assign any other value of the variable, the interpreter creates a new memory location for that value and then points the variable to the new memory location. This is the same process in which we create a new variable. Thus, it can be said that the variable is rebuilt in case of immutable data types on every assignment.
Program to represent the same:
v = 20
print(“Before: ”,id(v))
v = 21
print(“After: ”,id(v))
Output
Before: 140705582623120
After: 140705582623152
It can be seen that the memory location a variable is pointing after the assignment is different. The variable is entirely new and it can be said that the variable is rebuilt.
Question: Explain tuple slicing syntax with its parameters.
Answer: Syntax t=tuple_name[start : stop : step] Here,
♦ start integer where the slicing of the object starts.
♦ stop integer until which the slicing takes place. The slicing stops at index stop−1.
♦ step integer value which determines the increment between each index for slicing.
Question: What will be the output of following code?
x=44
y=30
tuple=(45, 65, 30, 78, 512)
if(x not in tuple):
print(“x is NOT present in given tuple”)
else :
print (“x is present in given tuple”)
if(y in tuple):
print(“y is present in given tuple”)
else:
print(“y is NOT present in given tuple”)
Answer: x is NOT present in given tuple y is present in given tuple
Question: Find and write the output of the following Python code.
t=(4, (8, 0, 7))
t1=(4, 7, (2, 8))
print(t.count(0))
print(t[1][2])
print(t*2)
print(len(t1))
print(t1[2])
print(t+t1)
Answer: Output
0
7
(4, (8, 0, 7), 4, (8, 0, 7))
3
(2, 8)
(4, (8, 0, 7), 4, 7, (2, 8))
Question: Write a Python code to remove an element ‘2’ from the following tuple.
tuple1 = (2, 5, 6, 9, 4)
Answer: tuple1 = (2, 5, 6, 9, 4)
list1 = list (tuple1)
list1. remove (2)
tuple1 = tuple (list1)
print (tuple1)
Question: TypeError occurs while statement 2 is running.
Give reason. How can it be corrected?
>>> tuple1 = (5) #statement 1
>>> len(tuple1) #statement 2
Answer: The ‘statement 1’ is creating a variable, tuple1 which is of ‘int’ data type. The ‘statement 2’ is checking for the length of the variable, but the argument passed is an ‘int’ data type.
The len() function can return the length only when the object is a sequence or a collection. This is the reason for the type error.
The error can be corrected by adding one comma after ‘5’ in statement 1, as this will create a tuple and as a tuple is a collection, len() function will not return an error.
The correct statement will be
>>> tuple1 = (5,)
>>> len(tuple1)
Question: Write a Python code to display all the elements of the following tuple except ‘H’.
t = (‘A’, ‘R’, ‘I’, ‘H’, ‘A’, ‘N’, ‘T’)
Answer: t = (‘A’, ‘R’, ‘I’, ‘H’, ‘A’, ‘N’, ‘T’)
t = t[0 : 3] + t[−3 : ]
print (t)
Output
(‘A’, ‘R’, ‘I’, ‘A’, ‘N’, ‘T’)
Question: Identify the error, if any in the following code.
t1=(2, 3, 4, ‘Hello’, 6,9)
print (min(t1))
Answer: min() function is used in tuple to return with minimum value out of elements in tuple.
Given code has an error because min() will work only if elements in a tuple are of same data type, i.e. (2, 3, 4, 7, 6, 9).

The tuple is: (23, 45, 20, 45, 65, 24)
SUM = 222
MEAN = 44.4
Question: A tuple is a collection of objects which ordered and immutable. Tuples are sequences, just like lists.
The differences between tuples and lists are, the tuples cannot be changed unlike lists and tuples use parentheses, whereas lists use square brackets.
We can use the index operator [] to access an item in a tuple, where the index starts from 0.
So, a tuple having 6 elements will have indices from 0 to 5. Trying to access an index outside of the tuple index range(6,7,… in this example) will raise an IndexError.
(i)Which types of elements are stored in tuple?
(ii)What do you mean by nested tuples?
(iii)Write the syntax to create tuple from an existing sequence.
(iv) Observe the output of giving code.
>>>t=[“T”, “U”, “P”, “L”, “E”]
>>>t2 = tuple(t)
>>>t2
(v)What is traversing a tuple in Python?
Answer: (i) Tuples hold a sequence of heterogeneous elements.
(ii) Nested tuples are tuple objects where the elements in the tuples can be tuples themselves.
(iii) new_tuple_name=tuple(sequence)
(iv) (‘T’, ‘U’, ‘P’, ‘L’, ‘E’)
(v) Traversing a tuple is a technique to access an individual element of that tuple.
Question: Write a Python program to search an element with its index number.
Answer: tuple1=(12,65,78,−63,−2,3,78,−12)
sm=0
x=int(input(“Enternumber tobesearched:”))
found=False
for i in range(len(tuple1)):
if(tuple1[i]==x):
found=True
print(“%d found at %drd
position”%(x,i))
break
if(found==False):
print(“%d is not in tuple”%x)
Output
Enter number to be searched: − 63
− 63 found at 3rd position
