Scrapy features and specs

  • Efficiency
    Scrapy is designed to be efficient and robust, capable of handling multiple tasks simultaneously and scraping large websites in a fast and reliable manner.
  • Built-in Tooling
    Scrapy comes with built-in tools for handling common tasks such as following links, extracting data using XPath and CSS, and exporting data in a variety of formats.
  • Customization
    Scrapy offers extensive customization options, allowing users to build complex spiders and modify their behavior through middleware and pipelines.
  • Python Integration
    Being a Python framework, Scrapy integrates seamlessly with the Python ecosystem, enabling the use of libraries like Pandas, NumPy, and others to process and analyze scraped data.
  • Community Support
    Scrapy has a large and active community, providing extensive documentation, tutorials, and third-party extensions to enhance functionality.
  • Asynchronous Processing
    Scrapy’s asynchronous processing model enhances performance by allowing multiple concurrent requests, reducing the time required for crawling sites.

Possible disadvantages of Scrapy

  • Steep Learning Curve
    For beginners, Scrapy's comprehensive feature set and the need for understanding concepts like XPath and CSS selectors can be challenging.
  • Resource Intensive
    Scrapy can be resource-intensive, potentially consuming significant memory and CPU, which can be problematic for scraping very large websites or running multiple spiders simultaneously.
  • Debugging Complexity
    Debugging Scrapy projects can be complex due to its asynchronous nature and the multiple layers of middleware and pipelines that need to be understood.
  • Overhead for Small Projects
    For simple or small-scale scraping tasks, the overhead of setting up and configuring a Scrapy project might be excessive, with simpler alternatives being more suitable.
  • Limited JavaScript Support
    Scrapy's out-of-the-box support for JavaScript-heavy websites is limited, requiring additional tools like Splash or Selenium, which can complicate the setup.
  • Dependency Management
    Managing Scrapy's dependencies and compatibility with other Python packages can sometimes be challenging, leading to potential conflicts and maintenance overhead.

PyQt features and specs

  • Comprehensive UI library
    PyQt provides a wide range of UI components, from basic widgets to advanced tools. This allows for the creation of highly sophisticated interfaces.
  • Cross-platform
    Applications built with PyQt can run on different operating systems such as Windows, macOS, and Linux without requiring significant changes in the code.
  • Integration with Qt Designer
    Developers can use Qt Designer to design and implement their UIs visually, which can then be seamlessly integrated with Python code in PyQt.
  • Powerful event handling
    PyQt includes a highly efficient event handling system that makes it easy to manage user interactions and system events.
  • Good documentation and community support
    PyQt is well-documented, and there's a large community of developers who can provide support and share resources.
  • Python-specific advantages
    Leveraging Python's simplicity and readability, PyQt allows for rapid development and easy maintenance of applications.

Possible disadvantages of PyQt

  • License considerations
    PyQt is available under the GPL and a commercial license. If you want to create proprietary software without open-sourcing your code, you need to purchase a commercial license.
  • Steep learning curve
    While PyQt is powerful, it can have a steep learning curve for newcomers, particularly those who are not familiar with Qt and its paradigms.
  • Performance overhead
    Being a binding for Qt, some operations may have extra overhead compared to native Qt applications written in C++.
  • Dependency on external libraries
    PyQt relies on the Qt library, which means that you have to manage and distribute these dependencies along with your application.
  • Large binary sizes
    Applications created with PyQt can result in relatively large binary sizes because of the included Qt binaries.
  • Fragmentation of tools
    There can be fragmentation concerns, as PyQt must stay in sync with Qt, and different versions of Qt may introduce changes that are not immediately reflected in PyQt.

  • Current problems and mistakes of web scraping in Python and tricks to solve them!
    One might ask, what about Scrapy? I'll be honest: I don't really keep up with their updates. But I haven't heard about Zyte doing anything to bypass TLS fingerprinting.

  • Scrapy Vs. Crawlee
    Scrapy is an open-source Python-based web scraping framework that extracts data from websites. With Scrapy, you create spiders, which are autonomous scripts to download and process web content. The limitation of Scrapy is that it does not work very well with JavaScript rendered websites, as it was designed for static HTML pages. We will do a comparison later in the article about this. - Source: dev.to / about 1 year ago

  • Best way to install qutebrowser?
    As for PyQt, that's developed entirely independently from Qt (by Riverbank Computing). The major/minor versions usually line up with the respective Qt releases (since the Qt release introduces new APIs, so a new PyQt release is needed to expose those to Python). However, it's versioned independently, and a new patch release of PyQt might be needed before/without Qt releasing a new patch release. For more details,... Source: about 4 years ago
