How to create a Array (not using list) in Python

If you come from C++, C#, or Java background, we all know arrays are a separate data type, but in Python most we hear is we can make use of a list for arrays. But do you know there is an array module that you can make use of specifically to create array types.

Using the array's module we can create a more memory-efficient array type that allows us to store elements of the same data type.

Example 1: Array of Integers

import array

int_array = array.array('i', [1, 2, 3, 4, 5])

print(int_array)

Example 2: Array of floats

import array

int_array = array.array('f', [1.5, 2.5, 3.9, 4, 50.1])
print(int_array)

List of types in Python Arrays

Type code	C Type	Python Type	Minimum size in bytes
'b'	signed char	int	1
'B'	unsigned char	int	1
'u'	wchar_t	str	2
'h'	signed short	int	2
'H'	unsigned short	int	2
'i'	signed int	int	2
'I'	unsigned int	int	2
'l'	signed long	int	4
'L'	unsigned long	int	4
'q'	signed long long	int	8
'Q'	unsigned long long	int	8
'f'	float	float	4
'd'	double	float	8
