Python - Find the Type of Array

Find the Type of Array in Python

In Python, you can find the type of given array using typecode attribute of the array object.

In this tutorial, you will learn how to find the type of given Python array, with examples.

To find the type of the given array my_array in Python, read the typecode attribute of the array as shown in the following.

my_array.typecode

The typecode attribute returns a string value representing the type of the elements in the given array. The typecode returned would be one of the type code shown in the following table.

Type Code	C data type	Python data type
'b'	signed char	int
'B'	unsigned char	int
'u'	Py_UNICODE	Unicode
'h'	signed short	int
'H'	unsigned short	int
'i'	signed int	int
'I'	unsigned int	int
'l'	signed long	int
'L'	unsigned long	int
'f'	float	float
'd'	double	float

1. Get Type of given Integer Array

In the following program, we take an integer array my_array, and then use typecode attribute to programmatically find the type of elements in the given array.

Python Program

import array as arr

my_array = arr.array('i', [100, 200, 300, 400])
my_array_typecode = my_array.typecode

print("Array type :", my_array_typecode)

Output

Array type : i

From the above table, typecode of 'i' represents signed int.

2. Get Type of given Character Array

In the following program, we take a unicode character array my_array, and then use typecode attribute to programmatically find the type of elements in the given array.

Python Program

import array as arr

my_array = arr.array('u', 'apple')
my_array_typecode = my_array.typecode

print("Array type :", my_array_typecode)

Output

Array type : u

In this Python Array tutorial, we learned how to find the type of given Python array, using typecode attribute, with examples.
