Arrays in Python

An array is a collection of elements that share the same data type.
It enables storage of multiple values within a single variable.
Memory allocation for array elements is sequential, promoting efficiency.

Working with Arrays

Python uses the array module to handle arrays; it must be imported before use.

General syntax for creating an array includes:

Array_Name = array.array('Type_Code' [, [Element_List]])

Type_Code indicates the datatype of the array's elements, while Element_List is optional for initialization.

Type Codes

Various Type_Codes can be utilized to define data types in an array:

Type_Code	Meaning
b	Signed Char
B	Unsigned Char
u	Unicode Char
h	Signed Short
H	Unsigned Short
i	Signed Int
I	Unsigned Int
l	Signed Long
L	Unsigned Long
f	float
d	double

Example Usage

A practical example defining an array:

import array
myArray = array.array('i', [1, 2, 3, 4, 5])
print(myArray) # Outputs the array contents

A dictionary example indicating array-like behavior:

Student = {"Name": "Yesha", "RollNumber": 13, "Standard": 9}
Student_Copy = Student.copy() 
print(Student_Copy) # Outputs: {'Name': 'Yesha', 'RollNumber': 13, 'Standard': 9}
