What Python Libraries For Data Science Are Used By Google?

Zaskakująco często dostaję to pytanie od znajomych z Polski — więc krótko i na temat: finał sezonu 7, czyli odcinek 16 'Outlander', miał swoją polską premierę 30 września 2023 roku. Emisja była zsynchronizowana z międzynarodową dystrybucją — po amerykańskiej premierze odcinek trafił na platformę streamingową dla widzów w Polsce (z napisami i/dubbingiem zależnie od oferty platformy). Dla wielu oznaczało to możliwość obejrzenia dokładnie tego samego odcinka, co widzowie za oceanem, tylko z lekkim przesunięciem wynikającym ze stref czasowych i polityki wydawniczej serwisu. Jeżeli szukasz konkretnego sposobu na obejrzenie teraz: sprawdzałem wtedy oferty największych usług streamingowych dostępnych w Polsce i to właśnie tam pojawiła się legalna emisja. Osobiście miałem mieszane uczucia wobec tego finału — emocje, piłowanie relacji i kilka scen, które długo mi nie schodziły z głowy.

Se a tua pergunta é sobre quando a sétima temporada de 'Outlander' ia aparecer na Netflix em Portugal, deixo aqui um panorama honesto e prático do que acompanhei: a transmissão original da temporada 7 estreou na Starz em duas partes — a Parte 1 começou a 16 de junho de 2023 e a Parte 2 estreou a 25 de maio de 2024. Tradicionalmente, a Netflix em Portugal costuma adicionar temporadas estrangeiras com algum atraso face à transmissão original nos EUA, porque os direitos de streaming são negociados e sincronizados de forma diferente em cada mercado. Até à minha última verificação em meados de 2024, a temporada 7 completa ainda não estava disponível na Netflix Portugal; isso não é incomum. Muitas séries chegam à Netflix local só depois do término da exibição na emissora original, ou então aos poucos (às vezes primeiro uma parte, depois a outra). Se tiveres paciência, o padrão recente tem sido a Netflix lançar a temporada completa algumas semanas a alguns meses após a última emissão na Starz — portanto, o mais provável era que a temporada 7 ficasse disponível em Portugal no verão ou início do outono de 2024. Para fãs impacientes, vale também ficar de olho em serviços ou comunicados oficiais, porque há sempre exceções e acordos específicos por país. Eu fiquei na expectativa como muitos: ver Jamie e Claire traduzidos para o catálogo português traz uma sensação especial de maratonas com amigos e memórias de leituras dos livros de Diana Gabaldon. Entretanto, enquanto a Netflix não anuncia a data exata para Portugal, a melhor referência continua a ser a própria janela das estreias na Starz — a 25 de maio de 2024 marca o fim da saga televisiva da temporada 7, o que normalmente abre caminho para que a Netflix a adicione pouco depois. De qualquer forma, a espera costuma valer a pena; gosto de rever certas cenas com legendas em português para apanhar nuances de diálogo que me escaparam nas legendas originais. Estou curioso para saber como te parece a adaptação da última parte, quando a vires.

I get a little giddy talking about practical tools, and the 'NYS Reference Table: Earth Science' is one of those underrated lifesavers for lab reports. When I'm writing up a lab, the table is my go-to for quick, reliable facts: unit conversions, constants like standard gravity, charted values for typical densities, and the geologic time scale. That means fewer dumb unit errors and faster calculations when I'm turning raw measurements into meaningful numbers. If my lab requires plotting or comparing things like seismic wave travel times, topographic map scales, or stream discharge formulas, the reference table often has the exact relationships or example diagrams I need. Beyond numbers, it also helps shape the narrative in my methods and discussion. Citing a value from 'NYS Reference Table: Earth Science' makes my uncertainty analysis cleaner, and including a screenshot or page reference in the appendix reassures graders that I used an accepted source. I usually highlight the bits I actually used, which turns the table into a tiny roadmap for anyone reading my report, and it saves me from repeating obvious—but grade-costly—mistakes.

I love geeking out about forensic detail, and with Linda Fairstein that’s one of the best parts of her Alex Cooper novels. If you want the meat-and-potatoes forensic stuff, start with 'Final Jeopardy'—it's the book that introduced Cooper and layers courtroom maneuvering over real investigative procedures. Fairstein’s background gives the series a consistent, grounded feel: you’ll see crime-scene processing, interviews that read like interviews (not melodrama), and plenty of legal-forensic interplay. Beyond the first book, titles like 'Likely to Die', 'Cold Hit', and 'Death Angel' each lean into different technical corners—DNA and database searches, digital leads and trace evidence, or postmortem pathology and toxicology. What I appreciate is how the forensic bits are woven into character choices, not just laundry lists of jargon. If you’re into techy lab scenes, focus on the middle entries of the series; if you like courtroom strategy mixed with lab work, the earlier ones are gold. Try reading one or two in sequence to see how Fairstein tightens the forensic realism over time—it's a little like watching a science lecture that’s also a page-turner.

Honestly, when I need something that just works without drama, I reach for pikepdf first. I've used it on a ton of small projects — merging batches of invoices, splitting scanned reports, and repairing weirdly corrupt files. It's a Python binding around QPDF, so it inherits QPDF's robustness: it handles encrypted PDFs well, preserves object streams, and is surprisingly fast on large files. A simple merge example I keep in a script looks like: import pikepdf; out = pikepdf.Pdf.new(); for fname in files: with pikepdf.Pdf.open(fname) as src: out.pages.extend(src.pages); out.save('merged.pdf'). That pattern just works more often than not. If you want something a bit friendlier for quick tasks, pypdf (the modern fork of PyPDF2) is easier to grok. It has straightforward APIs for splitting and merging, and for basic metadata tweaks. For heavy-duty rendering or text extraction, I switch to PyMuPDF (fitz) or combine tools: pikepdf for structure and PyMuPDF for content operations. Overall, pikepdf for reliability, pypdf for convenience, and PyMuPDF when you need speed and rendering. Try pikepdf first; it saved a few late nights for me.

Okay, if you want the short practical scoop from me: PyMuPDF (imported as fitz) is the library I reach for when I need to add or edit annotations and comments in PDFs. It feels fast, the API is intuitive, and it supports highlights, text annotations, pop-up notes, ink, and more. For example I’ll open a file with fitz.open('file.pdf'), grab page = doc[0], and then do page.addHighlightAnnot(rect) or page.addTextAnnot(point, 'My comment'), tweak the info, and save. It handles both reading existing annotations and creating new ones, which is huge when you’re cleaning up reviewer notes or building a light annotation tool. I also keep borb in my toolkit—it's excellent when I want a higher-level, Pythonic way to generate PDFs with annotations from scratch, plus it has good support for interactive annotations. For lower-level manipulation, pikepdf (a wrapper around qpdf) is great for repairing PDFs and editing object streams but is a bit more plumbing-heavy for annotations. There’s also a small project called pdf-annotate that focuses on adding annotations, and pdfannots for extracting notes. If you want a single recommendation to try first, install PyMuPDF with pip install PyMuPDF and play with page.addTextAnnot and page.addHighlightAnnot; you’ll probably be smiling before long.

I get excited about this stuff — if I had to pick one go-to for parsing very large PDFs quickly, I'd reach for PyMuPDF (the 'fitz' package). It feels snappy because it's a thin Python wrapper around MuPDF's C library, so text extraction is both fast and memory-efficient. In practice I open the file and iterate page-by-page, grabbing page.get_text('text') or using more structured output when I need it. That page-by-page approach keeps RAM usage low and lets me stream-process tens of thousands of pages without choking my machine. For extreme speed on plain text, I also rely on the Poppler 'pdftotext' binary (via the 'pdftotext' Python binding or subprocess). It's lightning-fast for bulk conversion, and because it’s a native C++ tool it outperforms many pure-Python options. A hybrid workflow I like: use 'pdftotext' for raw extraction, then PyMuPDF for targeted extraction (tables, layout, images) and pypdf/pypdfium2 for splitting/merging or rendering pages. Throw in multiprocessing to process pages in parallel, and you’ll handle massive corpora much more comfortably.

If you've ever dug into PDFs to tweak a title or author, you'll find it's a small rabbit hole with a few different layers. At the simplest level, most Python libraries let you change the document info dictionary — the classic /Info keys like Title, Author, Subject, and Keywords. Libraries such as PyPDF2 expose a dict-like interface where you read pdf.getDocumentInfo() or set pdf.documentInfo = {...} and then write out a new file. Behind the scenes that changes the Info object in the PDF trailer and the library usually rebuilds the cross-reference table when saving. Beyond that surface, there's XMP metadata — an XML packet embedded in the PDF that holds richer metadata (Dublin Core, custom schemas, etc.). Some libraries (for example, pikepdf or PyMuPDF) provide helpers to read and write XMP, but simpler wrappers might only touch the Info dictionary and leave XMP untouched. That mismatch can lead to confusing results where one viewer shows your edits and another still displays old data. Other practical things I watch for: encrypted files need a password to edit; editing metadata can invalidate a digital signature; unicode handling differs (Info strings sometimes need PDFDocEncoding or UTF-16BE encoding, while XMP is plain UTF-8 XML); and many libraries perform a full rewrite rather than an in-place edit unless they explicitly support incremental updates. I usually keep a backup and check with tools like pdfinfo or exiftool after saving to confirm everything landed as expected.
