Introduction to NumPy NumPy is a Python library used for working with arrays. NumPy is a library consisting of multidimensional array objects and a collection of routines for processing the arrays In Python we have lists that serve the purpose of arrays, but they are slow to process. NumPy aims to provide an array object which works faster than traditional Python lists. NumPy arrays are stored at one continuous place in memory unlike lists, so processes can access and manipulate them very efficiently. 

🐍📺 One of the most useful data structures in Python is the dictionary. In this video course, you’ll learn what a dictionary is, how dictionaries differ from lists and tuples, and how to define and use dictionaries in your own code #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! 👇

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

A Python dictionary is one of the most useful data structures you’ll work with, especially once you start handling real-world data. This guide shows you how to use a dictionary in Python, from creating key-value pairs to accessing, updating, and looping through nested data structures. If you’re learning Python fundamentals, this is one you’ll use constantly: https://buff.ly/TXy3Hjh

🐍📺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

Today I introduce you to Notebooks in databricks and how they are different from Python files! In my projects there were always big confusion when to use databricks and Python files. This one will clear it for you! Video in first comment! I hope you will enjoy it 👍

🐍📺 In this video course, you'll learn Python's namedtuple and how to use it in your code. You'll also learn about the main differences between named tuples and other data structures, such as dictionaries, data classes, and typed named tuples #python

I would like to share this moment with you: I have successfully published my first Python project. It is a simple cookbook and can be installed using the following link: https://lnkd.in/dQU_QQSA
