Python is a high-level programming language known for its simplicity and readability.
Python is an interpreted language, which means it does not need to be compiled before running.
It has a large standard library that provides many useful modules and functions.
Python supports multiple programming paradigms, including procedural, object-oriented, and functional programming.
It is widely used in web development, data analys...
reang is not a recognized term in Python development.
reang is not a Python keyword, module, or function.
There is no known reference or documentation for reang in Python.
It is possible that reang is a typo or a mispronunciation of another term.
A while loop is a control flow statement that allows code to be executed repeatedly based on a condition.
The loop continues until the condition becomes false
The condition is checked before each iteration
The loop body must include a way to modify the condition to avoid an infinite loop
A nested loop is a loop inside another loop. It allows iterating over multiple levels of data structures.
Nested loops are used when we need to perform repetitive tasks within repetitive tasks.
The inner loop is executed for each iteration of the outer loop.
Nested loops can be used to iterate over multi-dimensional arrays or nested data structures.
Example: Printing a multiplication table using nested loops.
A for loop is a control flow statement that iterates over a sequence of elements and executes a block of code for each element.
A for loop is used to iterate over a sequence such as a list, tuple, or string.
It consists of an initialization, condition, and increment/decrement statement.
The loop continues until the condition is false.
The code block inside the loop is executed for each element in the sequence.
Example: for
A keyword is a reserved word in a programming language that has a specific meaning and cannot be used as a variable name.
Keywords are used to define the syntax and structure of a programming language.
They cannot be used as variable names or identifiers.
Examples of keywords in Python include 'if', 'else', 'for', 'while', 'def', 'class', and 'import'.
A function is a block of code that performs a specific task and can be called multiple times throughout a program.
Functions are defined using the 'def' keyword followed by the function name and parentheses.
Functions can take arguments (inputs) and return values (outputs).
Functions can be called multiple times throughout a program, making code more efficient and modular.
Example: def add_numbers(x, y): return x + y

Data type is a classification of data based on the type of value it holds.
Data type determines the operations that can be performed on the data
Examples of data types include integers, strings, booleans, and floats
Data types can be static or dynamic depending on the programming language
PEP stands for Python Enhancement Proposal, which is a design document providing information or describing a new feature for Python.
PEP is used to propose and discuss new features or changes in Python
PEP is maintained by the Python community
PEP is assigned a number and categorized based on its type
Examples of PEPs include PEP 8 (Style Guide for Python Code) and PEP 20 (The Zen of Python)
Lists are mutable while tuples are immutable in Python.
Lists use square brackets [] while tuples use parentheses ().
Elements in a list can be added, removed, or modified while tuples cannot be modified.
Lists are used for collections of homogeneous items while tuples are used for heterogeneous items.
Lists are generally used for large collections of data while tuples are used for smaller collections or for data that shou...
Lambda functions are anonymous functions that can be defined in a single line of code.
Lambda functions are defined using the lambda keyword.
They can take any number of arguments, but can only have one expression.
They are often used as arguments for higher-order functions.
Example: lambda x: x**2 defines a lambda function that squares its input.
Arrays are homogeneous data structures while lists are heterogeneous data structures in Python.
Arrays are fixed in size while lists are dynamic.
Arrays can only contain elements of the same data type while lists can contain elements of different data types.
Arrays are faster and more memory-efficient for numerical operations.
Lists have more built-in functions and are more versatile for general-purpose programming.
Example...

Scaling a database involves horizontal or vertical scaling, with types including sharding, replication, and partitioning. Flask handles multiple requests using a WSGI server like Gunicorn.
Types of scaling include horizontal scaling (adding more servers), vertical scaling (upgrading server resources), sharding (splitting data across multiple servers), replication (copying data to multiple servers), and partitioning (div...
