use python language.

1(a) A Give the output for the

array([ 0, 1, 8, 27, 64, 125, 216, 343, 512, 729])

a. a[:6:2] = -1000 (ii) a[ : :-1] )

b. Display the values of 1D array using for loop?


c. Write a code to print a 3D array?


d. How to print the transpose of a 2D array?


e Write a function to sort the array row and coloumn wise ?

(b) You are the class representative and your class advisor always requests your help to prepare the result analysis after each internal assessment. One of the tasks that your class advisor has assigned to you is to find whether a student has scored a 0 in a course.Given the scores of the 'n' students in the class, write a python program to find whether how many students have scored a zero in a course.

(d) Design a 2D array to store the marks of six subjects of a student and display its total marks and average percentage?

(e) 5 DifferenCE between VIEW and COPY?

Answer 1

a )

a ) i ) [0,8,64]

ii ) [729,512,343,216,125,64,27,8,1,0]

b ) #Let a be the 1D array

for i in a:

print(i)

========================================================================================

c )

n = int(input("Enter your semester number: "))

if (n%2)!=0: #checking whether the semester is odd

print("Short vacation.")

else:

print("Long vacation.")

d )

import numpy as np
sum = 0
percentage = 0
l = np.array([[1,2,3,4,5,6,7],[10,20,30,40,50,60,70]])
for i in range(6):
sum += l[1][i]
percentage += (l[1][i] / 100)*100
average_percentage = (percentage) / 6
print("Total sum is: ", sum)
print("Average percentage is: ", average_percentage)
