Search & Filtering
you are given two given numbers, A and B where 1<= A <=B, write a program to find the number of perfect squares in range A to B (including A and B).
6. Create an array with whole numbers values from 0 to 10 and find what is the command to extract the elements in the following sequence -
array ([7,4,1])
7. Create a NumPy array having user input values and convert the integer type to the float type of the elements of the array. For instance:
Original array [1, 2, 3, 4]
Array converted to a float type: [ 1. 2. 3. 4.]
8. Write a NumPy program to append values to the end of an array. For instance:
Original array: [10, 20, 30]
After append values to the end of the array:
[10 20 30 40 50 60 70 80 90]
9. Create a 2 dimensional array with 3 rows and 3 columns containing random numbers from 1 to 9. Find the difference between the maximum element across the columns and the minimum element across the rows.
10. Create a 3*3 array having values from 10-90(interval of 10) and store that in array1. Perform the following tasks:
a. Extract the 1st row from the array.
b. Extract the last element from the array.
1. Create a list named ‘myList’ that has the following elements: 10,20,30,’apple’, True, 8.10.
a. Now in the ‘myList’, append these values: 30,40
b. After that reverse the elements of the ‘myList’ and store that in ‘reversedList’
2. Create a dictionary ‘Country’ that maps the following countries to their capitals respectively:
Country
India
China
Japan
Qatar
France
State
Delhi
Beijing
Tokyo
Doha
Marseilles
Find 2 commands to replace “Marseilles” with “Paris”.
3. Create the tuples given below
tuple_1 = (1,5,6,7,8)
tuple_2 = (8,9,4)
Identify which of the following code does not work on a tuple.
a) sum(tuple_1)
b) len(tuple_2)
c) tuple_2 + tuple_1
d) tuple_1[3] = 45

output : 12x^4 + 9x^3 - 5x^2 - x - 1Write a program to sort a list of integers using Insertion sort, Mergesort and Quicksort. First take as input the size ‘n’ of the array, then read in the ‘n’ input integers that need to be sorted.
Write a program that takes a sentence as input from the user, and prints the frequency of each
word in the sentence and neglects any punctuations. ‘.’,’,’,’!’ Input: Hello Amna. Amna is a good girl.
Output:
Hello: 1 Amna: 2 is: 1
a: 1 good: 1 girl:1
Write a program to sort a list of integers using Insertion sort, Mergesort and Quicksort. First take as input the size ‘n’ of the array, then read in the ‘n’ input integers that need to be sorted.
Write a program that keeps a person’s name and his/her contact number in a dictionary as key- value pairs. The program should display a menu that lets the user:
a. see a list of all contacts and their numbers,
b. add a new contact and number,
c. change the number of an existing contact, and
d. delete an existing contact and number.
The program should save the dictionary when the user exits the program. Each time the program starts, it should retrieve the dictionary from the file.

Create another list and store student answers in it. Your program should check for correct answers. A student needs to answer 30 correct answers out of 40 to pass the exam. Your program must show whether the student has passed or failed the exam, the total number of correct answers, the total number of incorrect answers and a list of incorrect questions.
