Usefulness of the -e Option with pip install
In certain situations, the -e (or --editable) option proves invaluable when executing pip install. This is particularly true when dealing with local projects during development.
How -e Works
As per the pip documentation, the -e option enables "editable mode." In this mode, the package is installed with a link to its original location. As a result, any changes made to the original package are automatically reflected in the installed package.
Why Use -e?
The primary use case for -e is during local package development. By installing the package in editable mode, developers can make changes to the code, save them, and see the updates reflected immediately in their environment. This eliminates the need to reinstall the package after every modification, significantly speeding up the development process.
Example Usage
To install a package locally using -e, provide the following command:
pip install -e .
Alternatively, if the package is located at a specific path, use the full path to the setup.py file:
pip install -e ~/ultimate-utils/ultimate-utils-proj-src/
Conclusion
The -e option in pip install serves as a valuable tool for local package development. By linking the installed package to its original location, it eliminates the need for constant reinstallation and allows developers to iterate quickly on their code.

This tutorial demonstrates how to use Python to process the statistical concept of Zipf's law and demonstrates the efficiency of Python's reading and sorting large text files when processing the law. You may be wondering what the term Zipf distribution means. To understand this term, we first need to define Zipf's law. Don't worry, I'll try to simplify the instructions. Zipf's Law Zipf's law simply means: in a large natural language corpus, the most frequently occurring words appear about twice as frequently as the second frequent words, three times as the third frequent words, four times as the fourth frequent words, and so on. Let's look at an example. If you look at the Brown corpus in American English, you will notice that the most frequent word is "th

Python provides a variety of ways to download files from the Internet, which can be downloaded over HTTP using the urllib package or the requests library. This tutorial will explain how to use these libraries to download files from URLs from Python. requests library requests is one of the most popular libraries in Python. It allows sending HTTP/1.1 requests without manually adding query strings to URLs or form encoding of POST data. The requests library can perform many functions, including: Add form data Add multi-part file Access Python response data Make a request head

PDF files are popular for their cross-platform compatibility, with content and layout consistent across operating systems, reading devices and software. However, unlike Python processing plain text files, PDF files are binary files with more complex structures and contain elements such as fonts, colors, and images. Fortunately, it is not difficult to process PDF files with Python's external modules. This article will use the PyPDF2 module to demonstrate how to open a PDF file, print a page, and extract text. For the creation and editing of PDF files, please refer to another tutorial from me. Preparation The core lies in using external module PyPDF2. First, install it using pip: pip is P
