numpy - capitalize() and title()

In this numpy tutorial, we will discuss capitalize() and title() functins performed on numpy array.

 

Introduction

numpy stands for numeric python which is used to perform mathematical operations on arrays.

It is a module in which we have to import from the python. 

Syntax to import:

import numpy

We can also use alias for the module 

For example,

import numpy as np

We can directly use np to call the numpy module.

Array

An array is an one dimensional data structure used to store single data type data.

I.E It will only store all integer data or all string type data.or all float type data.

We can create an numpy array by using array() function.

Syntax:

numpy.array(elements)

where, elements are the input data elements.

• capitalize()

​This method will capitalize only first character element present in the numpy array.

Syntax:

numpy.char.capitalize(array_input)

where, array_input is the numpy input array

Example:

In this example, we will create  an numpy array and capitalize the first character for each element.

#importing numpy module
import numpy

#create numpy array with 5 string elements
data=numpy.array(['php',"html css","jsp","go lang","css/jsp"])

#display the array
print(data)

#capitalize the array
print(numpy.char.capitalize(data))

Output:

We observed that in the second line of output, first character in each element is capitalized.

['php' 'html css' 'jsp' 'go lang' 'css/jsp']
['Php' 'Html css' 'Jsp' 'Go lang' 'Css/jsp']

• title()

​This method will capitalize the every string element present in the numpy array.

Syntax:

numpy.char.title(array_input)

where, array_input is the numpy input array

Example:

In this example, we will create  an numpy array and capitalize the  each element.

#importing numpy module
import numpy

#create numpy array with 5 string elements
data=numpy.array(['php',"html css","jsp","go lang","css/jsp"])

#display the array
print(data)

#apply title() on the array
print(numpy.char.title(data))

Output:

['php' 'html css' 'jsp' 'go lang' 'css/jsp']
['Php' 'Html Css' 'Jsp' 'Go Lang' 'Css/Jsp']
