Here is a simple example of an array containing 5 integers ~$ python

On a related topic, you should also know how to use Python Lists effectively. ‘d’ -> Represents floating point of size 8 bytes.‘f’ -> Represents floating point of size 4 bytes.‘L’ -> Represents unsigned integer of size 4 bytes.‘l’ -> Represents signed integer of size 4 bytes.‘w’ -> Represents unicode character of size 4 bytes.‘I’ -> Represents unsigned integer of size 2 bytes.‘i’ -> Represents signed integer of size 2 bytes.‘H’ -> Represents unsigned integer of size 2 bytes.‘h’ -> Represents signed integer of size 2 bytes.
‘u’ -> Represents unicode character of size 2 bytes. ‘c’ -> Represents character of size 1 byte. ‘B’ -> Represents unsigned integer of size 1 byte. ‘b’ -> Represents signed integer of size 1 byte. Typecodes are the codes that are used to define the type of array values or the type of array. This typecode represents signed integer whose size is 2 bytes. In the example above, typecode used is ‘i’. Here is a real world example of python array declaration : In the declaration above, ‘arrayIdentifierName’ is the name of array, ‘typecode’ lets python know the type of array and ‘Initializers’ are the values with which array is initialized. Here is how you do it:ĪrrayIdentifierName = array(typecode, Once you have imported the ‘array’ module, you can declare an array. Here is how you can import ‘array’ module in python : This is because array is not a fundamental data type like strings, integer etc. To use arrays in python language, you need to import the standard ‘array’ module. If you are new to Python, get started with the Python Introduction article. In this tutorial, we will understand the Python arrays with few examples. While python lists can contain values corresponding to different data types, arrays in python can only contain values corresponding to same data type. In Python, this is the main difference between arrays and lists. An array is a data structure that stores values of same data type.
