Return element-wise title cased version of string or Unicode in Numpy
To return element-wise title cased version of string or unicode, use the numpy.char.title() method in Python Numpy. Title case words start with uppercase characters, all remaining cased characters are lowercase.
The function title() 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 strings −
arr = np.array(['kATIE', 'jOHN', 'Kate', 'AmY', 'brADley'])
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 element-wise title cased version of string or unicode, use the numpy.char.title() method. Title case words start with uppercase characters, all remaining cased characters are lowercase −
print("
Result (title case)...
",np.char.title(arr))
Example
import numpy as np
# Create a One-Dimensional array of strings
arr = np.array(['kATIE', 'jOHN', 'Kate', 'AmY', 'brADley'])
# 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 element-wise title cased version of string or unicode, use the numpy.char.title() method in Python Numpy
# Title case words start with uppercase characters, all remaining cased characters are lowercase
print("
Result (title case)...
",np.char.title(arr))Output
Array... ['kATIE' 'jOHN' 'Kate' 'AmY' 'brADley'] Array datatype... <U7 Array Dimensions... 1 Our Array Shape... (5,) Number of elements in the Array... 5 Result (title case)... ['Katie' 'John' 'Kate' 'Amy' 'Bradley']
