Create Array of Integers 30 to 70

Write a NumPy program to create an array of integers from 30 to 70.

This NumPy program generates an array of integers ranging from 30 to 70. By using NumPy's array creation functions, it efficiently constructs the array with the specified sequence of integers. This program highlights how to create arrays with defined ranges in a straightforward manner.

Sample Solution :

Python Code :

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

# Creating an array of integers from 30 to 70 using np.arange()
array = np.arange(30, 71)

# Printing a message indicating an array of integers from 30 to 70
print("Array of the integers from 30 to 70")

# Printing the array of integers from 30 to 70
print(array) 

Output:

Array of the integers from 30 to70
[30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54
 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70]                         

Explanation:

In the above code -

array=np.arange(30,71): The np.arange() function creates a NumPy array containing values within a specified interval. In this case, it generates an array starting at 30 and ending before 71, with a default step size of 1. This results in an array of integers from 30 to 70. Since the step size is not explicitly specified, it defaults to 1.

The resulting 'array' will contain the integers from 30 to 70, inclusive: [30 31 32 33 ... 68 69 70].
