I'm excited to share a recent project where I used Python for web scraping and image downloading from IMDb's top movies list. This script collects movie data, including names, years, and ratings, and downloads movie posters, making the data easily accessible and organized. Here's a quick rundown of how it works: 🔍 Web Scraping with BeautifulSoup Using the powerful BeautifulSoup library, I parsed HTML content to extract essential movie information and image sources from IMDb. This allows for seamless data collection and processing. 📊 Data Handling and Storage I created a CSV file to store movie names, years, and ratings, ensuring that the data is well-organized and easy to manage. This step is crucial for any data analysis or presentation tasks. 📸 Automated Image Downloading The script automates the downloading of movie images, renaming them appropriately, and saving them to a specified directory. This feature is particularly useful for creating a local movie database with images. github repo https://lnkd.in/eKv9TzzC #python #webscraping

Day 53 of #100daysoflearning Web Scraping using Python🕸 So basically web scraping is process of extracting data from websites, means it involves fetching web pages parsing HTML content, and extracting the desired information. In today's lesson I learned about BeautifulSoup and Requests, how to extract data from websites, use of find and find_all as well extracting data (table) from website and saving it into csv files. This web scraping is commonly used for gathering data for research, analysis or building applications.

**🚀 Quick Guide to Essential Python Functions: Lambda, Map, Enumerate, Filter, and Zip!** 1. **Lambda:** Think of `lambda` as a shortcut for creating tiny, one-time-use functions on the fly. Perfect for quick operations without cluttering your code with full `def` functions. square = lambda x: x * x print(square(5)) # Outputs: 25 2. **Map:** Need to apply a function to every item in a list? `map` has you covered. It pairs well with lambdas to keep your code clean and efficient. numbers = [1, 2, 3, 4] squares = map(lambda x: x * x, numbers) print(list(squares)) # Outputs: [1, 4, 9, 16] 3. **Enumerate:** Ever wanted to loop through a list and know the index of each item? `enumerate` is your friend. It returns both the index and the value, making loops more informative. colors = ['red', 'blue', 'green'] for index, color in enumerate(colors): print(f"{index}: {color}") # Outputs: 0: red, 1: blue, 2: green 4. **Filter:** When you need to sift through a list and pick only the items that meet a certain condition, `filter` is the way to go. It’s like a sieve for your data. numbers = [1, 2, 3, 4, 5, 6] even_numbers = filter(lambda x: x % 2 == 0, numbers) print(list(even_numbers)) # Outputs: [2, 4, 6] 5. **Zip:** `zip` is like a zipper for your data, combining two (or more) lists into one, pairing up elements from each list by their positions. names = ['John', 'Jane', 'Doe'] ages = [23, 30, 40] combined = zip(names, ages) print(list(combined)) # Outputs: [('John', 23), ('Jane', 30), ('Doe', 40)]

Here is an applied example of using python to repeat a calculation using different values through the same formula. Lets say you work for Weather Services and they give you short time ⏲, maybe 2 minutes to convert temperature values from Degrees Celsius to Fahrenheit and you have to convert about 9 or more values and list them for your organisation task team. What would you do? Ofcoz Google has online calculators and so forth, so maybe 🤔 you can punch each value in the online Celsius to Fahrenheit conversion calculator.. thats great, but not the best option out there. On the attached figure, I used an example where a Python list is used to identify all the values or elements which are in degrees Celsius and have instantly converted them into the desired Fahrenheit values using the 'for loop statement of python'. So, how did i do it? On line 1 I define my variable of temperatures in Celsius as templist_c then I assign to this variable all 9 elements in the square bracket and separate them with a comma. On line 2 I define my for loop statement which will be used to repeat the calculation, substituting each value listed on line 1. The for loop statement ends with a colon wich is the reason for line 3 being indented. To finish the for loop statement, I had to dedent my line from line 3 to 4 by closing my parentheses () on line 4 after the print function. Line 3 is indented because it is the continuation of the for loop statement and the equation where all the elements listed on line 1 for temp_c list (Celsius values) will be substituted x9 times through the line 3 formula on the temp_c value. Line 4 then calls the values on Fahrenheit to be printed for all x9 values which were listed as Celsius units on line 1. The list gets printed for you exactly in two minutes or less Right 😜!!!....Tommoro I will use an example of shapefiles or feature-classes.

# Overview of Lists and Tuples - Lists are mutable sequences that can store a collection of arbitrary objects, defined by enclosing items in square brackets `[]`. 📝 - Tuples, on the other hand, are immutable sequences defined by enclosing items in parentheses `()`. 🔒 # Key Characteristics Both data types share several features: - They are ordered, meaning the sequence of elements is preserved. 📏 - They can contain arbitrary objects, including different data types. 🧩 - They support indexing and slicing operations. 🔍 # Comparison Table | Feature           | List | Tuple | |------------------------------|------|-------| | Ordered Sequence       | ✅  | ✅  | | Mutable            | ✅  | ❌  | | Can contain arbitrary objects | ✅  | ✅  | | Can be indexed and sliced   | ✅  | ✅  | | Can be nested         | ✅  | ✅  | # Creating Lists and Tuples - Lists can be created using literals, the `list()` constructor, or list comprehensions. 🛠️ - Tuples can be created similarly but require a comma for single-item tuples to distinguish them from other types. ⚙️ # Core Features # Indexing and Slicing Both lists and tuples allow access to elements via zero-based indexing and support negative indexing. Slicing enables retrieval of sub-sequences. 📊 # Nesting Lists and tuples can contain other lists or tuples, allowing for complex data structures. 🌐 # Mutability vs. Immutability Lists can be modified after creation (mutable), while tuples cannot (immutable). This distinction influences their use cases; lists are preferred for collections that may change, while tuples are used for fixed collections. ⚖️ #Python #Programming #Lists #Tuples #DataStructures #Coding #RealPython Citations: [1] https://lnkd.in/dCv95UiE

What are sorting algorithms? Sorting algorithms are methods used to order the elements of a list or array in a particular sequence (usually in ascending or descending order). Python Sorting Algorithms : https://lnkd.in/eqtyagiy JavaScript Sorting Algorithms: https://lnkd.in/eGhTU2vq 1. Sorting data can significantly enhance the efficiency of search algorithms. For example, binary search, which is much faster than linear search, requires data to be sorted before it can be applied. Sorted data allows algorithms to eliminate large portions of the data from consideration, thereby finding the desired information more quickly. 2. Sorting algorithms are used to organise data in a way that makes it more understandable and easier to visualise. sorting a list of names alphabetically or organising files by their creation dates helps users find information more intuitively. 3 . Finding the median, quartiles, or other statistical measures is more straightforward when the data is sorted. Similarly, identifying trends, patterns, and outliers is facilitated by working with ordered data. 4. Some algorithms, especially those dealing with numerical and statistical data, perform more efficiently or are easier to implement when the data is sorted. for example, algorithms for merging datasets, identifying duplicates, or performing set operations (like union, intersection, and difference) are significantly optimised on sorted data. #datascience #datastructures #python #javascript #webdevelopment #programming #sortingalgorithms
