    The array module in Python is a built-in module that provides an efficient way to create and manipulate arrays of basic values such as characters, integers, and floating-point numbers. Arrays in Python are similar to lists but are more memory-efficient and can only store elements of the same type.

    Creating an Array

    To create an array, you need to import the array module and use the array class. The array class requires a type code to specify the type of elements it will hold. Here is an example of creating an array of integers:

    import array

    # Create an array of integers
    numbers = array.array('i', [1, 3, 5, 7])
    print(numbers)
    Copied!

    Output:

    array('i', [1, 3, 5, 7])
    Copied!

    Type Codes

    The type code is a single character that specifies the type of elements in the array. Some common type codes are:

    • 'i': signed integer

    • 'f': float

    • 'd': double

    You can get a string representing all the type codes using the typecodes attribute:

    import array
    print(array.typecodes)
    Copied!

    Output:

    bBuhHiIlLqQfd
    Copied!
