NumPy: Create a new array of 3*5, filled with 2

NumPy: Array Object Exercise-40 with Solution

Write a NumPy program to create a new array of 3*5, filled with 2.

Pictorial Presentation:

Sample Solution:

Python Code:

# Importing the NumPy library with an alias 'np'
import numpy as np

# Creating a 3x5 array filled with 2s using np.full method and specifying the data type as unsigned int
x = np.full((3, 5), 2, dtype=np.uint)
print(x)

# Creating a 3x5 array filled with 2s using np.ones method and multiplying the array with 2 to get the desired values
# Specifying the data type as unsigned int
y = np.ones([3, 5], dtype=np.uint) * 2
print(y) 

Sample Output:

[[2 2 2 2 2]                                                           
 [2 2 2 2 2]                                                           
 [2 2 2 2 2]]                                                          
[[2 2 2 2 2]                                                           
 [2 2 2 2 2]                                                           
 [2 2 2 2 2]]

Explanation:

In the above code -

x = np.full((3, 5), 2, dtype=np.uint): The present line creates a 3x5 NumPy array x filled with the value 2 and with data type np.uint (unsigned integer).

y = np.ones([3, 5], dtype=np.uint) *2: The present line first creates a 3x5 NumPy array filled with ones and with data type np.uint using the np.ones() function. Then, it multiplies the array by 2, effectively filling it with the value 2.
