Summative Assessment
Total: 20 marks
Student Instructions:
1. You have 40 minutes to answer this assessment under examination
conditions (no talking, no copying or asking for help from the teacher or other
students).
2. If you need more space for any answer, use the pages provided at the back of
this booklet and clearly number the question.
3. For all numerical answers, full working of solutions should be shown and the
answer should be rounded to the correct number of significant figures and
given with an SI unit.
For all ‘describe’ or ‘explain’ questions, the answer should be in complete
sentences with all logic fully explained.
For compare and contrast both items in question should be fully explained

1.
Create a nested list called "My_School". Fill in the list with names of your friends.
My_School = [[‘Dastan’,”Zhangir”], [‘Nigger’, ‘Aset’]]
My_Class = My_School[0]
print(My_Class)
[1]
2.
Find out the difference between two methods of finding:
name="Hello,world"
print(name.count("h"))
print(name.index("h"))
Output
1 Not found
2. Not found
[2]
3.
Create a dictionaries called “Numbers” and fill it with integer keys. Sort the
dictionaries first ascending, then descending.
Numbers = {1: ‘one’, 2: ‘two’, 3: ‘three’}
print(sorted(Numbers.items()))
print(sorted(Numbers.items(), reverse = True))
[3]
4.
Write a Python program to multiply all the items in a list
List = (1,2,3,4,5,6,7)
for i in List:
total *= i
print("multiply of all elements in given list: ", total)
[4]
5.
Write the definition of nested list and string.
Nested lists in Python – a list that is element of other list
String in Python – type of object, list of element bytes
[2]
6. Create a dictionary with mixed key.
Dict = {1: ‘one’, ‘two’:2}
[1]
7. Write a Python program to add a set of values to a single key.
d = {}
set = {1,2,3,4,5,6,7}
sum = 0
for I in set:
sum += i
d[‘sum’] = sum
print(d)
[1]
8. Write a Python program to sum all the items in a dictionary.
my_dict = {'data1':100,'data2':-54,'data3':247}
sum(my_dict.values())
[1]
9. Write a Python program to iterate over dictionaries using for loops
Dict = {1: 1, 2: 4, 3: 9, 4: 16, 5: 25, 6: 36, 7: 49, 8: 64, 9: 81, 10: 100, 11: 121, 12: 144, 13:
169, 14: 196, 15: 225}
for key in Dict:
print( key + ‘ ’ Dict[key])
[2]
10. Write a Python script to print a dictionary where the keys are numbers between 1 and 15
(both included) and the values are square of keys.
dict = dict()
for i in range (1,16):
dict[i] = i*i
print(dict)
[3]
Output
{1: 1, 2: 4, 3: 9, 4: 16, 5: 25, 6: 36, 7: 49, 8: 64, 9: 81, 10: 100, 11: 121, 12: 144, 13: 169, 14:
196, 15: 225}
