For each element in a Numpy array, return a copy with the trailing spaces removed

NumpyServer Side ProgrammingProgramming

To return a copy of an array with the trailing spaces removed, use the numpy.char.rstrip() method in Python Numpy.

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

The chars parameter is a string specifying the set of characters to be removed. If omitted or None, the chars argument defaults to removing whitespace. The chars argument is not a suffix; rather, all combinations of its values are stripped.

Steps

At first, import the required library −

import numpy as np

Create a One-Dimensional array of string with some leading and trailing spaces −

arr = np.array([' Tom ', ' John ', ' Kate ', ' Amy ', 'Brad '])

Displaying our array −

print("Array...\n",arr)

Get the datatype −

print("\nArray datatype...\n",arr.dtype)

Get the dimensions of the Array −

print("\nArray Dimensions...\n",arr.ndim)

Get the shape of the Array −

print("\nOur Array Shape...\n",arr.shape)

Get the number of elements of the Array −

print("\nElements in the Array...\n",arr.size)

To return a copy of an array with the trailing spaces removed, use the numpy.char.rstrip() method −

print("\nResult...\n",np.char.rstrip(arr))

Example

import numpy as np

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

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

# Get the datatype
print("\nArray datatype...\n",arr.dtype)

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

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

# Get the number of elements of the Array
print("\nNumber of elements in the Array...\n",arr.size)
# To return a copy of an array with the trailing spaces removed, use the numpy.char.rstrip() method in Python Numpy
print("\nResult...\n",np.char.rstrip(arr))

Output

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

Array datatype...
<U6

Array Dimensions...
1

Our Array Shape...
(5,)

Number of elements in the Array...
5

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