Return a copy of an array with its elements centered in a string of length width in Numpy

To return a copy of an array with its elements centered in a string of length width, use the numpy.char.center() method in Python Numpy. The width is the length of the resulting strings. The function returns the output array of str or unicode, depending on input types.

The numpy.char module provides a set of vectorized string operations for arrays of type numpy.str_ or numpy.bytes_.

Steps

At first, import the required library −

import numpy as np

Create a One-Dimensional array of string −

arr = np.array(['bella', 'toM', 'john', 'katE', 'amy', 'brad'])

Displaying our array −

print("Array...<br>",arr)

Get the datatype −

print("\nArray datatype...<br>",arr.dtype)

Get the dimensions of the Array −

print("\nArray Dimensions...<br>",arr.ndim)

Get the shape of the Array −

print("\nOur Array Shape...<br>",arr.shape)

Get the number of elements of the Array −

print("\nElements in the Array...<br>",arr.size)

To return a copy of an array with its elements centered in a string of length width, use the numpy.char.center() method. The width is the length of the resulting strings −

print("\nResult...<br>",np.char.center(arr, width = 8))

Example

import numpy as np

# Create a One-Dimensional array of string
arr = np.array(['bella', 'toM', 'john', 'katE', 'amy', 'brad'])

# Displaying our array
print("Array...<br>",arr)

# Get the datatype
print("\nArray datatype...<br>",arr.dtype)

# Get the dimensions of the Array
print("\nArray Dimensions...<br>",arr.ndim)

# Get the shape of the Array
print("\nOur Array Shape...<br>",arr.shape)

# Get the number of elements of the Array
print("\nElements in the Array...<br>",arr.size)

# To return a copy of an array with its elements centered in a string of length width, use the numpy.char.center() method in Python Numpy
# The width is the length of the resulting strings
print("\nResult...<br>",np.char.center(arr, width = 8))

Output

Array...
['bella' 'toM' 'john' 'katE' 'amy' 'brad']

Array datatype...
<U5

Array Dimensions...
1

Our Array Shape...
(6,)

Elements in the Array...
6

Result...
[' bella ' ' toM ' ' john ' ' katE ' ' amy ' ' brad ']
