15. Write a program to input a number and display whether it is a prime number or not.
Ans. [1]: num = int(input("Enter a number: "))
if num > 1:
for i in range(2, int(num / 2) + 1):
if (num % i) == 0:
print(num, 'is not prime')
break
else:
print(num, "is a prime number")
else:
print(num, "is not a prime number")
Enter a number: 12
12 is not a prime number
16. Write a program to input two numbers and swap both the numbers without using the third number.
Ans. [1]: x = int(input("Enter the value of x: "))
y = int(input("Enter the value of y: "))
print("Numbers before swapping: %d %d\n" %(x,y))
x = x + y
y = x - y
x = x - y
print("Numbers after swapping: %d %d\n"%(x,y))
Enter the value of x: 22
Enter the value of y: 14
Numbers before swapping: 22 14
Numbers after swapping: 14 22
17. Using Numpy Package:
• Create a 4×2 array with random integer.
• Create 3×3 array with all zeros.
Ans. [1]: import numpy as np
array1 = np.random.randint(0, 10, (4, 2))
print("4x2 Array with Random Integers:")
print(array1)
import numpy as np
array2 = np.zeros((3, 3))
print("\n3x3 Array with Zeros:")
print(array2)
4x2 Array with Random Integers:
[[5 1]
[7 8]
[0 1]
[1 5]]
3x3 Array with Zeros:
[[0. 0. 0.]
[0. 0. 0.]
[0. 0. 0.]]
18. Using Matplotlib and the given data, plot a bar chart:
No of people voted = [23,45,31,40,35]
Area covered = [‘a1’,’a2’,’a3’,’a4’,’a5’]
