Return an array with the elements of a Numpy array right-justified in a string of length width

To return an array with the elements of an array right-justified in a string of length width, use the numpy.char.rjust() method in Python Numpy. The "width" parameter is the length of the resulting strings.

The function returns an output array of str or unicode, depending on input type. 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(['Tom', 'John', 'Kate', 'Amy', 'Brad'])

Displaying our array −

print("Array...
",arr)

Get the datatype −

print("
Array datatype...
",arr.dtype)

Get the dimensions of the Array −

print("
Array Dimensions...
",arr.ndim)

Get the shape of the Array −

print("
Our Array Shape...
",arr.shape)

Get the number of elements of the Array −

print("
Elements in the Array...
",arr.size)

# To return an array with the elements of an array right-justified in a string of length width, use the numpy.char.rjust() method in Python Numpy

# The "width" parameter is the length of the resulting strings

print("
Result...
",np.char.rjust(arr, width = 15))

Example

import numpy as np

# Create a One-Dimensional array of string
arr = np.array(['Tom', 'John', 'Kate', 'Amy', 'Brad'])

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

# Get the datatype
print("
Array datatype...
",arr.dtype)

# Get the dimensions of the Array
print("
Array Dimensions...
",arr.ndim)

# Get the shape of the Array
print("
Our Array Shape...
",arr.shape)

# Get the number of elements of the Array
print("
Number of elements in the Array...
",arr.size)

# To return an array with the elements of an array right-justified in a string of length width, use the numpy.char.rjust() method in Python Numpy
# The "width" parameter is the length of the resulting strings
print("
Result...
",np.char.rjust(arr, width = 15))

Output

Array...
['Tom' 'John' 'Kate' 'Amy' 'Brad']

Array datatype...
<U4

Array Dimensions...
1

Our Array Shape...
(5,)

Number of elements in the Array...
5

Result...
[' Tom' ' John' ' Kate' ' Amy'
' Brad']
