💡 Why is below expression in Python evaluated to "True"?

→→ not False == True is not True == True ←←

Originally Asked By: @DataIlm

I will try to answer this one in the easiest possible way.

🧵 👇
2 important things we need to understand while solving this one.

1️⃣ Operator Precedence
2️⃣ Operator Associativity
1️⃣ Operator Precedence

✪ Logical 'not' operator has "lower precedence" than Comparison Operators (here '==') and Identity Operators (here 'is not').

✪ Comparison Operators and Identity Operators have same precedence.

🔀 Shuffle a List in JavaScript and Python

You can build

👉 your own shuffled playlist like in Spotify
👉 a game of cards
👉 a lottery picker app
👉 and what not

How? 🧵 👇
1️⃣ What is Shuffle?

✪ Shuffle is like sorting where it reorders the original list of elements.

✪ But unlike sorting, shuffle doesn't define any specific rule how to order these elements. Output is always non-predictive.
2️⃣ How does Shuffle work?

✪ As output is non-predictive, hence there is some randomness.

✪ So the algorithm we will write need to have randomness included.

🪜 Introduction to GraphQL

"FAANG might have changed to MANGA, but GraphQL is still GraphQL" 😉

🧵 👇
1️⃣ What is GraphQL?

GraphQL is

→ a query language for your API (explained in 6️⃣)

2️⃣ What is an API?

🛢SQL and NoSQL Database

👉 What are these?
👉 Key Differences
👉 How to choose between them?

🧵 👇
1️⃣ What is a Database?

A database is an organised collection of data stored in a computer system (typically a server machine, but can be any machine) so that it can be accessed and managed easily.
✪ Initially each database had a separate way of data management. The way one database was storing and managing data may vary from another.

✪ But with time this practice got normalised. The "Relational Database" design came into picture.
