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...\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 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("\nResult (title case)...\n",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...\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 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("\nResult (title case)...\n",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']
