Introduction In this Python code snippet, we are going to implement an easy hangman solver using simple source code. The game code is adapted to work with both Python 2.x and Python 3.x. The example provided is a console based application for beginners. Let us get started with the tutorial… Python 2.x program There is
Introduction Ready for more code snippets? In this post, we are going to talk about random numbers in Python. Have you ever thought about what random means or even if randomness makes any sense in the context of computing! (as computers execute instructions blindly). Is randomness useful? can we apply it in real life computational
Introduction Unicode is an important topic in computing but it is a little bit confusing. In particular, it can be more confusing in the context of Python programming language. For that reason, the aim of our article today is to clarify the ambiguity and hopefully put things into perspective. Beginners may get confused because they
Introduction It is hard (even impossible) to find a real world application not using string comparison. It can be used in database lookup, searching for files on disk, sorting contacts and many other scenarios. String comparison in Python is not hard as we will demonstrate in today’s code snippets. Let us get started… Python string
Introduction Today, we are going to discuss how to convert numbers to strings and visa versa. It is a straightforward Python topic but it is important as well. There are various real life scenarios where type conversion is required. Before elaborating more, let us mention two example use cases to get a taste of what
Table of contents Introduction What is a regular expression? What is Python raw string? Python RE module Python regular expressions syntax summary Regular expressions flags re.match re.search Why use re.match? Regular expression compilation re.match and re.search examples re.fullmatch Match objects re.findall re.finditer re.split re.sub Summary References Introduction Welcome to a new Python code snippets post.
Introduction Python programming language is a dynamically typed language. In other words, variable types are not explicitly declared as in statically typed languages (ex. C++). Instead, type checking is performed at runtime as opposed to compile time. The debate of which is better? a dynamically typed or statically typed language is not discussed in this
Introduction Welcome to a new code snippet in Python. Today, we are going to clarify the difference between items() and iteritems() methods when using a Python dictionary. Let us first quickly refresh our memory about lists, tuples and dictionaries in Python: A list is an array data structure that can be edited A tuple is
Introduction In today’s Python code snippet, we are going to talk about deleting, removing and popping list elements: remove method: takes a value as input, searches for it, removes the first match. If the item is not found it errors out del function: removes an item at a specific index, can delete all elements or
Welcome to a new Python code snippet. In this post, we are going to suggest a couple of methods to flatten a list of lists. The final output is going to be a one dimensional list. Let us take an example: Using nested loops Using list comprehensions Using sum function Using list extend Using chain
