WS 6 – Tuples

1. W hy tuples are called immutable types? What are mutable counterparts of tuples? How individual elements of tuples accessed?

2. H ow do you create the following tuples :

i. (4,5,6)
ii. (-2,1,3)
iii. (-9,-8,-7,-6,-5)
iv. (0,1,2)

3. If a=(5,4,3,2,1,0) evaluate the following expression :

i. a[0]
ii. a[1]
iii. a[a[0]]
iv. a[a[-1]]
v. a[a[a[a[2]+1]]]

4. If a=(1,2,3) , b=(4,5,6) and c=5 evaluate the following statement :

i. print(a+b)
ii. print(a*b)
iii. print(a*c)
iv. print(a+c)

5. W rite the output :

>>> t=(((('a',1),'b','c'),'d',2),'e',3)
>>> print(len(t))
6. W rite a python code to accept a tuple T of n integers and print the smallest and second smallest element.
7. W hat will be stored in the variables a,b,c,d,e,f,g,h
perc=(88,85,80,88,83,86)
a=perc[2:2]
b=perc[2:]
c=perc[:2]
d=perc[:-2]
e=perc[-2:]
f=perc[2:-2]
g=perc[-2:2]
h=perc[:]

8. G iven a tuple namely cars with car names as elements :

(‘Toyota’,’Honda’,’GM’,’Ford’,’BMW’,’Porshe’,’Ferrai’,’Mercedes’) Write a program to print names of the cars in the index range 2 to 6 both inclusive. The output should also include the index in words as shown below :
One                 Honda
Two                 GM

9. A nswer the following :

i. How is an empty tuple created.
ii. How is a tuple containing just one element created.
iii. How can you add an extra element to a tuple.
iv. When will you prefer a tuple over list.
v. Does the slice operator produce a new tuple

10. P redict the output of the following:

Tup1=(1,)*3
Tup1[0]=2
print(Tup1)
Tup2=((1,2),)*7
print(Tup2)
print(len(Tup2[3:8]))

11. P redict the output of the following:

Tup1=('Rachna Sagar')*2
print(type(Tup1))
print(Tup1)
print(len(Tup1))

12. C reate the following tuple using a for loop :

i. A tuple containing squares of the integers 1 to 50.
ii. The tuple (‘a’,’bb’,’ccc’,’dddd’) that ends with 26 copies of the letter z.

13. W rite a python program that creates a tuple storing first 10 terms of Fibonacci series.

14. H ow tuples and string are similar?

15. W hat do you mean by tuple unpacking? Give example
