Return List of Words in String Using Separator in NumPy

To return a list of the words in the string using separator as the delimiter string, use the numpy.char.split() method in Python Numpy −

• The 1st parameter is the input array
• The 2nd parameter is the separator

If maxsplit parameter is given, at most maxsplit splits are done. The function split() returns an array of list objects.

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 an array −

arr = np.array(["Bella-Cio", "Brad-Pitt", "Katie-Perry"])

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 list of the words in the string using separator as the delimiter string, use the numpy.char.split() method −

print("
Result...
",np.char.split(arr, '-'))

Example

import numpy as np

# Create an array
arr = np.array(["Bella-Cio", "Brad-Pitt", "Katie-Perry"])

# 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 list of the words in the string using separator as the delimiter string, use the numpy.char.split() method in Python Numpy
# The 1st parameter is the input array
# The 2nd parameter is the separator
print("
Result...
",np.char.split(arr, '-'))

Output

Array...
['Bella-Cio' 'Brad-Pitt' 'Katie-Perry']

Array datatype...
<U11

Array Dimensions...
1

Our Array Shape...
(3,)

Elements in the Array...
3

Result...
[list(['Bella', 'Cio']) list(['Brad', 'Pitt']) list(['Katie', 'Perry'])]
