What is the numpy.char.encode() function in Python?

Overview

The char.encode() function in R is simply used to call the str.decode element-wise.

Syntax

char.encode(a, encoding=None, errors=None)

Parameter value

The char.encode() function takes the following parameter values:

  • a: This represents the array of strings or Unicode object.
  • encoding: This represents the name of the encoding. Some encodings include: utf-8, UTF-16, UTF-32, ascii, cp037, etc.
  • errors: This specifies how errors should be handled. This is optional.

Return value

The char.encode() function returns an array object.

Note: It is worth noting that the type of output will depend on the value of the encoding specified.

Code example

import numpy as np
# creating an array
myarray = np.array(["Theo", "How", "Are", "You"])
# to eccode the array using ascii encoding
To_encode = np.char.encode(myarray, encoding='cp037')
print(To_encode)

Code explanation

  • Line 1: We import the numpy module.
  • Line 4: We create an array myarray using the array() function.
  • Line 7: We encode the array with the ascii encoding using the char.encode() function. The result is assigned to a variable To_encode.
  • Line 9: We print the encoded variable To_encode.
