FastAPI: A modern, fast (high-performance) web framework for building APIs with Python 3.7+ based on standard Python type hints. It's known for its automatic interactive API documentation, performance, and ease of use.
Hello guys.
I'm very excited to tell you all that Pythonist is now officially on YouTube, so do us a favor and subscribe as we will be posting three new videos every week.

The append method in Python adds its argument as a single element to the end of a list. List_a.append(list_b) adds the entire list_b list as a single element to list_a, resulting in list_a containing [1, 2, 3, [4, 5, 6]]. So, len(list_a) will return 4, the correct answer is 4.
argparser (argument parser) is a Python module used for parsing command-line arguments. It simplifies the process of creating command-line interfaces (CLIs) for your Python scripts by automatically generating help messages, handling argument parsing, and enforcing argument types.
This setup ensures type safety by restricting the mode parameter to only accept the specified literal values, enhancing code readability and maintainability
PyTorch: A popular open-source machine learning library developed by Facebook's AI Research lab (FAIR). It's primarily used for applications such as natural language processing, computer vision, and deep learning. One of its key features is its dynamic computation graph.
Bottle: A fast, simple, and lightweight WSGI micro web-framework for Python. It's designed for small web applications and APIs and is known for its simplicity and ease of use.
Flask: A lightweight web framework that is simple and easy to use, yet powerful enough to build complex web applications. It's known for its simplicity and flexibility, allowing developers to choose the tools and libraries they prefer.
functools.partial allows you to fix a certain number of arguments of a function and generate a new function. This can make your code cleaner and more modular!

The code initializes a dictionary my_dict with one key-value pair: "key": 10.
Then, it updates the value associated with the key "key" to "changed".
Finally, it prints the dictionary, which now contains the updated value for the key "key". So, the output is {'key': 'changed'}.
f Strings (Formatted String Literals)
Prefix: f or F
Purpose: Provides a way to embed expressions inside string literals, using curly braces {}.
Use Case: Useful for including variables and expressions inside strings in a readable and concise manner.

the is operator checks if two variables refer to the same object in memory.
As a result, a is b evaluates to True because a and b refer to different list objects, even though their contents are the same.
Python Error 011: FileNotFoundError.
Cause: occurs when a program attempts to access or open a file that does not exist in the specified location.
Solution:
>>>Check File Existence
>>>Use Absolute Paths
>>>Alternatively you can Handle Exceptions by using the Try Except block.

When you use the * operator with a dictionary in Python, it unpacks the keys of the dictionary. So, when you execute print(*my_dict), it's equivalent to print(1, 2), which prints the keys of the dictionary my_dict. the output of print(*my_dict) will be 1 2

In Python, the .find method is not available for lists; it is specifically a string method. If you want to find the index of an element in a list, you should use the .index method instead. in this case the answer would be Error.
RAG stands for Retrieval-Augmented Generation, a method used in natural language processing that combines retrieval-based and generative-based approaches to improve the performance of tasks like question answering and document generation.
Pytest: A popular testing framework for Python. It allows developers to write simple and scalable test cases for their Python code. Some key features of pytest are:
>Simple Syntax.
>Parameterized Tests.
>Powerful Assertions.
>Plugin Ecosystem.
>Integration with Other Tools.
With Statement in Python:
In Python, the with statement replaces a try-catch block with a concise shorthand. More importantly, it ensures closing resources right after processing them. A common example of using the with statement is reading or writing to a file.
If you need to gather a bunch of data from a website, doing it manually can be tedious.
Instead, you can use a scraping tool like Scrapy to help automate the process.
This course teaches you how to use it – and how to build your first Scrapy spider.
A common task of a programmer or engineer is to split an absolute path into the directory name and the last part of the path, which could be a file or folder.

In Python, floating-point numbers are represented in scientific notation, and 10e-17 represents 10×10−1710×10−17, which is a very small number close to zero, So, the output of the code will be:
10.0
CherryPy: A minimalist web framework that allows developers to build web applications in a similar way to building any other object-oriented Python program.
We just hit 500 followers guys . Thanks for all your support to all who followed.
I know we can hit a thousand followers before the end of this year 🫡. Fortunately I will soon be renewing my subscription.
Thanks once again 😁.

the answer is (D) because In the expression a + 3, Python tries to concatenate a string (a, which is "6") with an integer which is not possible. String concatenation in Python requires both operands to be strings.
TensorFlow and PyTorch, two popular deep learning frameworks, differ in their approach to computational graphs. TensorFlow uses a static computational graph, where the graph structure is defined before the actual computation occurs. In contrast, PyTorch employs a dynamic

()*3 creates an empty tuple () and then repeats it three times using the multiplication operator. Therefore, the result is a tuple containing three empty tuples: (), (), (). Which is A.
