Building a Real-time Dashboard with FastAPI and Svelte In this tutorial, you'll learn how to build a real-time analytics dashboard using FastAPI and Svelte. We'll use server-sent events (SSE) to stream live data updates from FastAPI to our Svelte frontend, creating an interactive dashboard that updates in real-time. Start: https://testdriven.io/blog/fastapi-svelte/

Nested Loops in Python Nested loops in Python allow you to place one loop inside another, enabling you to perform repeated actions over multiple sequences. Understanding nested loops helps you write more efficient code, manage complex data structures, and avoid common pitfalls such as poor readability and performance issues.

Get a weather forecast without API and complex settings in Python We use the wttr.in (https://github.com/chubin/wttr.in) service — a simple and powerful tool that shows the weather right in the console. To work with the HTTP request, you only need one library - requests. Installing it is very easy: pip install requests Here is the minimal and clear code to get the forecast: import requests city = input("Enter the city name: ") url = f"https://wttr.in/{city}" try: response = requests.get(url) print(response.text) except Exception: print("Oops! Something went wrong. Please try again later.") Just enter the desired city and get a detailed forecast with temperature, precipitation Try it yourself 😏

Regular Expressions in Python Regular expressions (regex) in #Python are used for searching, matching, and manipulating strings based on patterns. In Python, regular expressions are implemented in the re module. Main functions of the re module: 🔸re.match(): Checks if the beginning of a string matches a given pattern. 🔸re.search(): Searches for a pattern in a string and returns the first matching object found. 🔸re.findall(): Finds all occurrences of a pattern in a string and returns them as a list. 🔸re.finditer(): Finds all occurrences of a pattern and returns them as an iterator. 🔸re.sub(): Replaces all occurrences of a pattern with a given string. 🔸re.split(): Splits a string by a given pattern. Usage examples:

import re

# Example string
text = "The rain in Spain falls mainly in the plain."

# 1. re.match()
match = re.match(r'The', text)
if match:
    print("Match found:", match.group())
else:
    print("No match found")

# 2. re.search()
search = re.search(r'rain', text)
if search:
    print("Search found:", search.group())
else:
    print("No search found")

# 3. re.findall()
findall = re.findall(r'in', text)
print("Findall results:", findall)

# 4. re.finditer()
finditer = re.finditer(r'in', text)
for match in finditer:
    print("Finditer match:", match.group(), "at position", match.start())

# 5. re.sub()
substitute = re.sub(r'rain', 'snow', text)
print("Substitute result:", substitute)

# 6. re.split()
split = re.split(r'\s', text)
print("Split result:", split)

Explanation of the example: > re.match(r'The', text): Checks if the string text starts with "The". > re.search(r'rain', text): Searches for the first occurrence of "rain" in the string text. > re.findall(r'in', text): Finds all occurrences of "in" in the string text. > re.finditer(r'in', text): Returns an iterator that iterates over all occurrences of "in" in the string text. > re.sub(r'rain', 'snow', text): Replaces all occurrences of "rain" with "snow" in the string text. > re.split(r'\s', text): Splits the string text by spaces (whitespace characters). Additional pattern examples: \d: Any digit. \D: Any character except a digit. \w: Any letter, digit, or underscore. \W: Any character except a letter, digit, or underscore. \s: Any whitespace character. \S: Any non-whitespace character. .: Any character except a newline. ^: Start of the string. $: End of the string. *: 0 or more repetitions. +: 1 or more repetitions. ?: 0 or 1 repetition. {n}: Exactly n repetitions. {n,}: n or more repetitions. {n,m}: Between n and m repetitions. Regular expressions are a powerful tool for working with text and can be useful in a wide range of tasks, from simple input validation to complex text parsing. 💊

html-to-markdown A modern, fully typed Python library for converting HTML to Markdown. This library is a completely rewritten fork of markdownify with a modernized codebase, strict type safety and support for Python 3.9+. Features: ⭐️ Full HTML5 Support: Comprehensive support for all modern HTML5 elements including semantic, form, table, ruby, interactive, structural, SVG, and math elements ⭐️ Enhanced Table Support: Advanced handling of merged cells with rowspan/colspan support for better table representation ⭐️ Type Safety: Strict MyPy adherence with comprehensive type hints Metadata Extraction: Automatic extraction of document metadata (title, meta tags) as comment headers ⭐️ Streaming Support: Memory-efficient processing for large documents with progress callbacks ⭐️ Highlight Support: Multiple styles for highlighted text (<mark> elements) ⭐️ Task List Support: Converts HTML checkboxes to GitHub-compatible task list syntax nstallation

pip install html-to-markdown

Optional lxml Parser For improved performance, you can install with the optional lxml parser:

pip install html-to-markdown[lxml]

The lxml parser offers: 🆘 ~30% faster HTML parsing compared to the default html.parser 🆘 Better handling of malformed HTML 🆘 More robust parsing for complex documents Quick Start Convert HTML to Markdown with a single function call:

from html_to_markdown import convert_to_markdown

html = """
<!DOCTYPE html>
<html>
<head>
    <title>Sample Document</title>
    <meta name="description" content="A sample HTML document">
</head>
<body>
    <article>
        <h1>Welcome</h1>
        <p>This is a <strong>sample</strong> with a <a href="https://example.com">link</a>.</p>
        <p>Here's some <mark>highlighted text</mark> and a task list:</p>
        <ul>
            <li><input type="checkbox" checked> Completed task</li>
            <li><input type="checkbox"> Pending task</li>
        </ul>
    </article>
</body>
</html>
"""

markdown = convert_to_markdown(html)
print(markdown)

Working with BeautifulSoup: If you need more control over HTML parsing, you can pass a pre-configured BeautifulSoup instance:

from bs4 import BeautifulSoup
from html_to_markdown import convert_to_markdown

# Configure BeautifulSoup with your preferred parser
soup = BeautifulSoup(html, "lxml")  # Note: lxml requires additional installation
markdown = convert_to_markdown(soup)
