Tuple Question Answer in Python for CBSE Class 11 Computer Science. Assignment solutions of Sumita arora book. There are conceptual, application based and program based questions and answers for the preparation of annual exam.

## Type A : Conceptual based Questions

**Q.1. Discuss the utility and significance of Tuples, briefly.**

**Answer :**

It is a type of arrays. In python it is immutable type of container .

**Q.2. If a is (1, 2, 3)****(a) what is the difference (if any) between a * 3 and (a, a, a)?****(b) is a * 3 equivalent to a + a + a ?****(c) what is the meaning of a[1:1] ?****(d) what is the difference between a[1:2] and a[1:1] ? **

**Answer : **

A = a*3 >>>(1,2,3,1,2,3,1,2,3)

(a,a,a) will print .>>>((1,2,3),(1,2,3),(1,2,3))

B = yes

C = it will print empty tuple.

D = a[1:2] will print index number 1 while,a[1:1] print empty tuple.

**Q.3.Does the slice operator always produce a new tuple ?**

** ANSWER :**

Yes ,it will print a part of tuple.

**Q.5.Are the following two assignments same ? Why / why not ? (b) T3 = (3, 4, 5) T4 = ((3, 4, 5)) (a) T1 =3, 4, 5 T2 = (3,4 ,5)**

**ANSWER:**

(a) t1==t2 True Because t1 and t2 have same value.

(b) t3 == t4 False Because T3 is a tuple but T4 is a nested tuple.

**Q.6. What would following statements print ? Given that we have tuple = (‘t’, ‘p’, ‘I’) (a) print(“tuple”) (b) print(tuple(“tuple”)) (c) print (tuple)**

**ANSWER =**

A = ‘tuple’

B = (‘t’,’u’,’p’,’l’,’e’)

C = (‘t’,’p’,’l’)

**Q.7. How is an empty tuple created ?**

**Answer : **

By two way we can create a empty tuple first by given value with out any valueLike :- a =()Second by defining tuple A=tuple ()

**Q.8. How is a tuple containing just one element created ?**

**Answer** =

3 ways are there_

a =’b’ a=(‘b’,) a=tuple ([‘a’])

**Q.9. How can you add an extra element to a tuple ?**

**Answer **:

By using + operatorExample:- a=(‘p’,’y’,’t’,’h’,’o’)

b =(‘n’)

print (a+b)

>>>(‘p’,’y’,’t’,’h’,’o’,’n’)

print(t4)

print(t5)

print(16)

(f)

t = (‘a’, ‘b’, ‘c’, ‘d’, ‘e’)

1, 2, 3, 4, 5, = t

(g)

t = (‘a’, ‘b’, ‘c, d’, ‘e’)

1n, 2n, 3n, 4n, 5n = t

(h)

t = (‘a’, ‘b’, ‘c’, ‘d’, ‘e’)

x, y, z, a, b = t

(i)

t = (‘a’, ‘b’, ‘c’, ‘d’, ‘e’)

a, b, c, d, e, f = t

**Answer:**

(a) IndexError: tuple index out of range

(b) TypeError: ‘tuple’ object does not support item assignment

(c) TypeError: unsupported operand type(s) for +: ‘int’ and ‘tuple’

(d) TypeError: unsupported operand type(s) for -: ‘tuple’ and ‘tuple’

(e) TypeError: can’t multiply sequence by non-int of type ‘tuple’

(f) syntax error

(g) invalid syntax

(h) It will give no error.

(i) ValueError: not enough values to unpack (expected 6, got 5)

**Q.4.What would be the output of following code if**

ntpl = (“Hello”, “Nita”, “How’s”, “life?”)

(a, b, c, d) = ntpl

print ( “a is:”, a)

print(“b is:”, b)

print(“c is:”, c)

print(“d is:”, d)

ntpl = (a, b, c, d)

print (ntpl[0][0] + ntpl[1][1], ntpl[1])

**Answer:**

a is: Hello

b is: Nita

c is: How’s

d is: life?

Hi Nita

**Q.5.Predict the output: **

tuple_a = ‘a’, ‘b’

tuple_b = (‘a’, ‘b’)

print (tuple_a == tuple_b)

**Answer :**

Output:-

True

**Q.6. Find the error. Following code intends to create a tuple with three identical strings. But even after successfully executing following code (No error reported by Python). The len() returns a value different from 3 Why ?**

tup1 = (‘Mega’) * 3

print(len(tup1))

**Answer :**

Here ‘tup1’ is not tuple, it is string.

Program is: –

tup1 = (‘Mega’,) * 3

print(len(tup1)

len() return 3

**Q.7. Predict the output**:

tuple1 = (‘Python’) * 3

print(type(tuple1))

**Answer :**

Output: –

<class ‘str’>

>>>

**Q.8. Predict the output:**

x = (1, (2, (3, (4,))))

print (len(x))

print( x[1][0])

print(2 in x)

y = (1, (2, (3,), 4), 5)

print len((y))

print(len(y[1])

print( y[2] = 50)

z = (2, (1, (2,), 1), 1)

print (z[z[z[0]]])

**Answer : ** It will give an error

**Q.9.What will the following code produce**?

Tup1 = (1,) * 3

Tup1 [0] = 2

print (Tup1)

**Answer : **

It will give an error that ‘TypeError: ‘tuple’ object does not support item assignment’.

**Q.10.What will be the output of the following code snippet?**

Tup1 = ((1, 2),) * 7

print (len(Tup1 [3: 8 ]))

**Answer: **

Output is: –

4

>>>

Because

Tup1 = ((1, 2),) * 7

After this Tup1 become

((1, 2), (1, 2), (1, 2), (1, 2), (1, 2), (1, 2), (1, 2))

Now Len(Tup1[3:8]) strat from index number 3 , 4, 5, 6. **So, output is 4.**

**Q.10. Computing mean. Computing the mean of values stores in a tuple is relatively simple. The mean is the sum of the values divided by the number of values in the tuple.mean = Sum of frequency /no. of frequencyWrite a program that calculate and display the mean of a tuple with numeric element .**

Answer:i=0 a = eval (input ("Enter the numeric tupal =")) b = 0 for i in range (len(a)): b = b +a[i] print('mean of tupal=',b/len(a)) #print(i)

**Q.11.Mean of means . given a nested tuple tup1 = ((1,2),(3,4.15,5.15),(7,8,12,15)) .write a program that display the mean of individual element of tuple tup1 and then displays the mean of these computed means.**

Answer:i=0 a = eval (input ("Enter the numeric tupal =")) b = 0 for i in range (len(a)): b = b +a[i] print('mean of tupal=',b/len(a)) #print(i)
