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

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

print("
Result...
",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...
",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 a copy of an array with the trailing spaces removed, use the numpy.char.rstrip() method in Python Numpy print("
Result...
",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']
