Return a list of the words in the string using separator as the delimiter string 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'])]
