What are Dictionaries in Python ? In the previous articles, we explored various data structures in Python. When it comes to managing key-value pairs, the dictionary data structure becomes particularly useful. Dictionaries keys are immutable example -...
Date: 2020-10-06 This tutorial demonstrates two methods to check if a key exists within a Python dictionary: the if-in statement and the __contains__(key) method. Both approaches are illustrated with code examples showing how to efficiently determin...
Date: 2021-06-30 This tutorial demonstrates how to sort a Python dictionary by its values using the sorted() function. The article provides a simple Python script example showcasing this functionality, along with a brief explanation of the sorted() ...
Chapter 1: Introduction – Why Go Beyond Lists? 🚀 Lists are the bread and butter of Python programming, beloved for their flexibility and ease of use. But as your Python projects scale up-handling more data, demanding better performance, or requiring...
Chapter 1: The Map – Discovering Python Dictionaries 🗺️ Welcome, adventurer! Before we dive into ancient temples, let’s get our bearings. Imagine Indiana Jones’ satchel: it holds precious artifacts, each labeled for quick access. That’s what a Pytho...
Tuples A list is a mutable data type. Mutable data can be updated anytime. Tuple is a immutable data. It can not be modified. >>> tuple1 = (1, 2, 3) >>> print(tuple1) (1, 2, 3) >>> tuple2 = 1, 2, 3 >>> print(tuple2) (1, 2, 3) Read data from a tu...
📝 Quick Summary: The python-benedict library enhances Python's built-in dictionary with keylist, keypath, and keyattr support, simplifying access to nested data. It provides integrated I/O operations for common data formats like JSON, YAML, and CSV,...
Introduction The defaultdict, a part of collections module, is a powerful extension of the standard dict class. It overrides one method __missing__ and adds one writable instance variable default_factory. If default_factory is None, it behaves like a...
Understanding the Problem There are strings as s and t. The length of s and length of t are equal as len(s) == len(t). This problem requires deciding whether s and t are isomorphic, which means they have the same structure, or pattern. As an example,...
Understanding the Problem There are two strings given. One is pattern, and another one is a string with spaces. If the pattern is ”abba” and the string is ”dog cat cat dog”, the first index ”a” takes ”dog”, the second index ”b” takes ”cat”, the third...
