Python Dictionary Data Structure Explained

🐍📺 In Python, collections of text are called strings. In this course, you'll learn about this fundamental data type and the string methods you can use to manipulate strings #python

🐍📺 In this video course, you'll learn how to use the pathlib module to carry out file path operations with Python. These operations include creating, iterating over, searching for, moving, and deleting files and folders #python

🐍📺 Using OrderedDict in Python [Video] In this video course, you'll learn Python's OrderedDict and how to use it in your code. You'll also learn the main differences between regular dictionaries and ordered dictionaries. #python

“Let’s begin learning Python together.”📊📈⏳ Another Test for your Python Basics! 🐍 Consistency is key when learning to code. Let’s test your logic with this simple Python snippet. Looking at the variables and the print statement, what do you think the final output will be? Pick your answer: A) The result is: 10 B) The result is: 20 C) The result is: 30 D) The result is: c E) Error Drop your answer in the comments below! 👇

🐍📺Check if a Python String Contains a Substring [Video] In this video course, you'll learn to check whether a string contains a substring. You'll also learn about idiomatic ways to inspect a substring further and search for substrings in pandas #python

🐍📰 Python 3's pathlib Module: Taming the File System How to effectively work with file system paths in Python 3 using the new "pathlib" module in the standard library #python

🐍📺 In this video course, you'll learn what the Python with statement is and how to use it with existing context managers. You'll also learn how to create your own context managers. #python

🐍📺In this Python Basics video course, you'll learn to use conditional logic to write programs that perform different actions based on different conditions. Paired with functions and loops, conditional logic allows you to write complex programs. #python

Do you know the difference between @staticmethod and @classmethod in Python? Most beginners use one or the other without fully understanding why. @staticmethod does not receive any implicit argument. It belongs to the class only for organisational purposes — it could live anywhere, but it makes sense to keep it there. @classmethod receives the class itself as the first argument, conventionally called cls. This means it can access and modify class-level data. The rule is simple: if the method needs the class, use @classmethod. If it needs nothing, use @staticmethod. In the image below you can see both methods applied to the same class. validate_email does not need to know anything about the class — it just validates a string. increment_count needs access to user_count, which belongs to the class itself, not to any specific instance. 💭 Have you ever used one when you should have used the other? #Python #Backend #PythonDeveloper #BuildingInPublic #HKingsJourney

Evaluating Expressions in Python using eval() While practicing on HackerRank, I explored the power of Python’s built-in eval() function. *Problem Statement: Read a mathematical expression from input and evaluate its result. Solution: # Enter your code here. Read input from STDIN. Print output to STDOUT expression = input() print(eval(expression)) * How it works: input() takes the expression as a string (e.g., "3 + 5 * 2") eval() evaluates the string as a Python expression The result is printed directly Example: Input: 3 + 5 * 2 Output: 13 *Important Note: eval() is powerful but should be used carefully, as it can execute arbitrary code. It’s safe in controlled environments like coding platforms, but not recommended for untrusted input in real-world applications. -> Always exciting to learn how Python simplifies complex tasks with minimal code! #Python #HackerRank #CodingPractice #Programming #LearnToCode #100DaysOfCode
