Overview

The char.chararray.astype() method in Python returns a copy of an array that is cast to a specified type.

Syntax

char.chararray.astype(dtype)
Syntax for the char,chararray.astype() function

Parameter value

The char.chararray.astype() method takes the parameter value dtype. This represents the typecode or the data type to which the array is cast.

Example

import numpy as np
# Creating an input array 
x = np.array([1, 20.57, 2.05, 100.5, 0.5])

myarray = x.astype(dtype=int)
print(myarray)
Implementing the char.chararray.astype() method

Explanation

  • Line 1: We import the numpy module.
  • Line 3: We create an input array x using the array() function.
  • Line 5: We implement the char.chararray.astype() method on the x array by converting its elements to int data types. We assign the result to a variable myarray.
  • Line 6: We print the variable myarray.
