Python tkinter programming source code trabalhos

I’m working on a Python project that scrapes data from multiple websites and parses it into a structured format for analysis. However, I’m running into a few bugs with the scraping logic, parsing issues, and some edge cases that the code doesn’t handle well. I need a freelancer to help fix these bugs and optimize the code. Project Details: - Some websites are throwing errors when scraping specific pages (need help with error handling). - Data parsing is inconsistent; sometimes the data isn’t cleaned properly (need help with parsing and formatting). - The code runs slowly for large datasets (need optimization). - The code doesn’t handle certain edge cases where the webpage layout changes (need fixes for those). I will provi...

...file built from two sources—Propstream and Apollo.io. From Propstream, the focus is commercial properties and apartment assets; every record must include full property details plus up-to-date owner contact information. will serve as a second source so the final list contains additional prospects pulled from that platform (matching or related to the same asset classes). All data must be scraped, deduped, and formatted in a single spreadsheet so I can sort, filter, and launch campaigns immediately. Use whatever stack you prefer—Python, Selenium, BeautifulSoup, Apify, or similar—but the workflow has to respect each site’s TOS and deliver reliable results. Deliverables • CSV/Excel file with Propstream property details and owner contacts f...

...clear, well-commented rules. • Optional if you add simple interactivity (fade-in, lightbox, or arrow navigation). • A brief README or inline comments walking me through how to swap in my own photos, change the number of columns, and how to include it in an existing html landing page. This is to go on to a white bg page. Keep everything framework-free—no Bootstrap, no jQuery—so the code stays easy to maintain and drop into any site. Aim for quick load times and sensible semantics (figure, img, figcaption where appropriate). Responsive behaviour is desirable but doesn’t need to be pixel-perfect on every device; a straightforward media query that stacks images on small screens will do. When you’re done, send a zipped package containing the ...

...critical: headings must be standardised, units normalised and categorical values written the same way across the entire sheet. I am happy for you to use Python, Scrapy, BeautifulSoup, Selenium, AI-assisted extraction—whatever combination you trust—to pull the information, as long as the final file is accurate and complete. Data standardisation is essential. To keep things efficient I’d like a small sample delivered early so we can confirm structure before you harvest the full set. Once the sample is approved, scrape the remaining URLs, run your data-cleaning pipeline and hand over the finished spreadsheet. If a field is genuinely missing on the source page, leave it blank; otherwise every row should be populated. Deliverables • Sample Excel f...

The workflow should be straightforward: open the connection, retrieve the user data, run the analysis, then return or print the results in a readable format (JSON or a simple report is fine). Please keep the code modular so I can extend it later. Deliverables • Source script with clear connection parameters abstracted for security • Brief setup/readme so I can run it locally or on a server • Sample output file showing the analysis results I’m flexible on language—Python with pandas or SQL-native procedures both work—as long as the...

...am happy with Python, Node.js, or another lightweight option—choose what you are most comfortable with and note any external libraries you plan to rely on (e.g., jq, pandas, lodash). • Input: one or more JSON files, either through the command line or piped stdin. • Filtering: accept simple key=value pairs as well as compound rules (AND / OR, numeric ranges, date comparisons). • Output: print to stdout or save to a new file, preserving valid JSON structure. Optional flags for pretty-print or compact mode are welcome. Deliverables 1. Source code with clear inline comments. 2. A concise README showing setup, sample commands, and a couple of example filter rules. 3. Brief guidance on extending the filter logic should new criteria be nee...

...images or video assets are required—so the script should concentrate on crafting clear, well-structured paragraphs that blend key facts, points of interest, and cultural context in a lively yet concise style. The tool can be written in any mainstream language (Python, JavaScript, or similar) as long as it runs locally from the command line and outputs clean, UTF-8 text that I can drop straight into our platform. A simple way for me to pass in a list of place names—CSV, JSON, or command-line arguments—is essential. Deliverables • Source code with clear inline comments • A brief README explaining setup, dependencies, and how to invoke the generator • Sample output for five example locations so I can verify the tone, length, and...

...Generalist for my team. The right fit should hold a bachelor’s degree in HR (or a closely related field), feel comfortable navigating common HR software suites, and demonstrate solid communication skills from the first interaction. Here’s what I expect from you: • Craft and post an engaging job ad on suitable channels (LinkedIn Recruiter, university career boards, niche HR forums, etc.). • Actively source and screen applicants, using your own ATS or mine. • Conduct initial interviews that probe technical knowledge, software familiarity, and interpersonal abilities. • Present a concise shortlist with interview notes and your personal recommendations. • Coordinate final-round interviews and gather feedback until I sign off on a hire. ...

...and location selectors. • Rotate user-agents / proxies or apply any other anti-bot tactics necessary to stay undetected. • Capture and log errors so a failed request never silently drops a row. • Be easy for me to rerun on demand—command-line or small web UI is fine, as long as setup is straightforward. I’m comfortable with Python (BeautifulSoup, Selenium, Playwright, Scrapy, etc.) or another language you can justify, as long as you hand over all source code, dependency files, and a quick start README. A brief demo video or screenshots validating the scraper against at least one aggregator and one direct company site will serve as the final acceptance test. When you bid, point me to a project where you’ve scraped dynamic ...

I have already gathered a sizeable spreadsheet of phone numbers, email addresses and IP addresses; now I need all of tho...metadata and any scripts or command logs you run so the work is reproducible. Acceptance criteria 1. Each data point I provide appears in the final graph, either linked or explicitly marked “no link found.” 2. Any claimed tie between a person and a location is backed by at least two independent artefacts. 3. Methodology is transparent—if you use SpiderFoot, Recon-ng, Python notebooks, WiGLE, Shodan, etc., include the steps or code. Feel free to lean on the OSINT stack you trust most; I care about accuracy, transparency and a clean hand-off more than the specific tools. Timeline is roughly one week from kickoff, and I will supply an NDA...

...synths for EDM, cinematic pads, and orchestral libraries such as Spitfire LABS or Vital. After the initial setup, I’ll need occasional follow-up hours for troubleshooting and basic instruction. My DAW background is limited to some Cakewalk tinkering three decades ago, so please be prepared to explain recording, editing, and routing in plain language and demonstrate core Reaper workflows (MIDI programming, audio tracking, comping, automation, exporting). When you reply, let me know: 1. Your rate for the first dedicated setup hour. 2. Your hourly rate for any future troubleshooting or teaching sessions. 3. The time zone you’ll be calling from and typical availability. If you have proven remote-setup experience, patience with beginners, and a portfolio that...

I am kicking off a large-scale, Uber-style real-estate platform and I’m taking a feature-by-feature approach so development can run in parallel across distinct code bases. We will begin with the Customer app and treat it as a stand-alone product that plugs into a larger micro-services architecture later. Scope of this first engagement You will deliver a clean, well-documented API plus a lightweight front-end for the Customer module. The core flows I need working are: • Property search with robust filters • Booking and scheduling of property visits (calendar integration, confirmation logic, basic notifications) • User profile management (sign-up, KYC placeholder, saved searches, favourites) Everything must be built in its own repo and deployed to its own...

I want to fine-tune autonomous flights in Mission Planner for my drone fleet so we can run repeatable surveying and mapping jobs over d...basic post-processing flow for turning imagery into accurate maps or 3-D models. • A quick screen-record or live walk-through so I can see the workflow and tweak it for new job sites. Deliverables will be reviewed in SITL; the plan must load in the latest Mission Planner without warnings and finish the simulated mission with at least 80 % image overlap. If you like scripting the planner in Python, great—otherwise a solid manual setup is fine. Right now the focus is strictly on drones for urban surveying and mapping, but an approach that could later scale to mixed environments is ideal. Let’s get this template locked down s...

I’m putting together a comprehensive backtest... splits, and dividends. • Consistent symbol mapping so delistings, mergers, and ticker changes don’t break the series. • A single, tidy delivery format—CSV files are fine, but a lightweight SQL or Parquet database also works if you prefer. • A short README that explains field definitions, adjustment methodology, and any known data caveats. If you already have a reliable data pipeline in Python, R, or another language, feel free to leverage it; just make sure the final output is easy for me to import into pandas. Accuracy and completeness over the full decade are far more important than ultra-low latency. Once I confirm everything loads and reconciles against a spot check of raw exchange data, I&...

I need a compact script (Python is fine, but I am open to Node or any language the broker SDK supports) that can talk simultaneously to Kotak Neo, Fyers, and Dhan REST/WebSocket APIs. The workflow is straightforward: • On my signal I will pass a symbol, entry price and total quantity. The program must split that quantity 25 %, 25 %, 50 % and fire three separate limit orders (target 1, target 2, target 3). • A fixed 2-point stop-loss order has to be attached immediately; if the broker supports OCO/bracket use it, otherwise emulate it through the API. • As soon as either the stop or the final target is hit, the logic should place a fresh re-entry order at the original entry price, repeating the same 25/25/50 allocation. This loop continues until I manuall...
