Working with Binary numbers BASE(..., 2, 7) and bit operations BITXOR, BITAND I recently came across an Excel challenge from Chinmay Amte on LinkedIn and I plan to post my solution here because it contains some 'off the beaten track' techniques that might be of s...
PyGAD is a Python library for implementing the genetic algorithm. To install it and get started, check out the tutorial 5 Genetic Algorithm Applications Using PyGAD. As the name implies, we’ll show you how to develop five different applications using the library. In Building a Game-Playing Ag...

Just like Python dictionaries, you wrap JSON objects inside curly braces ({}). In line 1, you start the JSON object with an opening curly brace ({), and then you close the object at the end of line 20 with a closing curly brace (}). Note: Although whitespace doesn’t matter in ...
print("Python\b\b\booo") # prints Pytooo The backspace control character\bmoves the cursor one character back. In our case, we use three backspace characters to delete three letters and replace them with three o characters. print("Towering\tinferno") # prints Towering inferno ...
Where other languages, like C#, Java, Ruby or F#, have some form of multiple-choice decision-making construct (usually denoted by the keyword “switch”), Python chooses instead to stick with the conceptually simpler “if-then-elif” collection. In other words, Python has no “switch...
2.5. Working With FilesPython provides a built-in function open to open a file, which returns a file object.f = open('foo.txt', 'r') # open a file in read mode f = open('foo.txt', 'w') # open a file in write mode f = open('foo.txt', 'a') # open a file in ...
In this tutorial, you'll dive deep into working with numeric arrays in Python, an efficient tool for handling binary data. Along the way, you'll explore low-level data types exposed by the array module, emulate custom types, and even pass a Python array
Now let's see examples of multi-dimensional dynamic arrays where you are unsure of the number of items of the Array. For example, the following code snippet creates two multi-dimensional arrays with no limit. int[,] numbers = new int[,] { { 1, 2 }, { 3, 4 }, { 5, 6 } };...
A further subcategory of LOB is the temporary LOB, which can be either a BLOB, CLOB, or NCLOB but is stored in the temporary tablespace until you free it. Note that older versions of Oracle provided the LONG and LONG RAW types for character and binary data, respectively. With Oracle9i th...
