Question

7. i) Let n and k be some given positive integers, and x a 1-dimensional NumPy array of length n. Write a Python code that creates the 2-dimensional NumPy array which has k columns all identical to x. You may import numpy as np Perform the test case: ne5 k-3 x = np.arange(0,1,0.2) # the output should be [[. 0. 0.] [0.2 0.2 0.2] [0.4 0.4 0.4) (0.6 0.6 0.6) [0.8 0.8 0.8]] 7. ii) Let a, b, c be 1-dimensional NumPy arrays of the same length. Write a Python code that creates the 2-dimensional NumPy array which has rows a, b, c. You may import numpy as np Perform the test case: a = np.arange(0,1,0.2) b = np.arange(1,2,0.2) C = np.arange(2,3,0.2) # the output should be [Co. 0.2 0.4 0.6 0.8) (1. 1.2 1.4 1.6 1.8) [2. 2.2 2.4 2.6 2.8]]

Answer 1

import numpy as np
##(1)
n=5
k=3
x=np.arange(0,1,0.2)
z = np.zeros((n,k))
for i in range(n):
for j in range(k):
z[i][j]=x[i]
print(z)
a=np.arange(0,1,0.2)
b=np.arange(1,2,0.2)
c=np.arange(2,3,0.2)
##(2)
z1 = np.zeros((3,a.size))
for i in range(3):
for j in range(a.size):
if(i==0):
z1[i][j]=a[j]
if(i==1):
z1[i][j]=b[j]
if(i==2):
z1[i][j]=c[j]
print(z1)
