NumPy is an abbreviated form of Numerical Python. It is used for different types of scientific operations in python. Numpy is a vast library in python which is used for almost every kind of scientific or mathematical operation. It is itself an array which is a collection of various methods and functions for processing the arrays.

Printing a NumPy array without brackets

Suppose that we are given a numpy array that contains some numerical values. When we print a numpy array, the compiler will display the output as an array where all the elements are encapsulated in square brackets [ ]. We need to find a way so we can print a numpy array without brackets.

For this purpose, we need to convert each element of the numpy array into a string and then we will join each string using the str.join() method.

The string is a group of characters, these characters may consist of all the lower case, upper case, and special characters present on the keyboard of a computer system. A string is a data type and the number of characters in a string is known as the length of the string.

Let us understand with the help of an example,

Python code to print a NumPy array without brackets

# Import numpy
import numpy as np

# Creating a numpy array
arr = np.array([10,20,30,46,50,62,70,80,94,100])

# Display original array
print("Original Array:\n",arr,"\n")

# Converting each element of array into string
res = map(str, arr)

# Joining the string
res = ' '.join(res)

# Display result
print("Result:\n",res)

Output:
