[Arrays](https://www.educative.io/answers/what-are-arrays-in-python) in python behave very similar to lists but they have the same data type of values stored in it. The data type is specified at the array creation time by using a single character is called the **type code**. 

Below is the table for type codes, used for defining arrays in python, and their corresponding C++ data type. 


|  **Type Code**   |  **C++ Type**   |   **Python Type**  |  **Minimum Sizes in Bytes**   |
| --- | --- | --- | --- |
|'c'|char|character|1|
|   'b'  |  signed char   |  int   |   1  |
|    'B' |   unsigned char  |  int   |  1   |
|   'u'  |  Py_UNICODE   |   unicode character  |  2   |
|   'h'  |  signed short   |  int   |   2  |
|    'H' |  unsigned short   |   int  |  2   |
|    'i' | signed int    |   int  |  2   |
|    'I' |  unsigned int   |  long   |  2   |
|   'l'  |  signed long   |   int  | 4    |
|   'L'  |   unsigned long  |   long  |  4   |
|   'f'  |  float   |   float  |   4  |
|    'd' |  double   | float     |  8   |



Below is an example of an array, of type `char` in C++ and `character` in python.

import array as arr #importing array module

a = arr.array('c',['a','e','i','o','u']) #defining array of type char and size 5
print(a) # printing value at 2nd index

Python

#include <iostream>
using namespace std;

int main() {
  char a[5]= {'a','e','i','o','u'}; // defining array of type char and size 5
  
  for (int i=0; i<5;i++){
  cout<<a[i]<<" "; // printing the array
  }
 
}

What are type codes in Python?

Arrays in Python use type codes to define data types, ensuring all elements have the same type.

Type Code	C++ Type	Python Type	Minimum Sizes in Bytes
‘c’	char	character	1
‘b’	signed char	int	1
‘B’	unsigned char	int	1
‘u’	Py_UNICODE	unicode character	2
‘h’	signed short	int	2
‘H’	unsigned short	int	2
‘i’	signed int	int	2
‘I’	unsigned int	long	2
‘l’	signed long	int	4
‘L’	unsigned long	long	4
‘f’	float	float	4
‘d’	double	float	8
