extracts structured data from text using user-defined delimiters (strings or regex)
Project description
extracts structured data from text using user-defined delimiters (strings or regex)
Tested against Windows / Python 3.11 / Anaconda
pip install parifinder
parifinder extracts structured data from text using user-defined delimiters (strings or regex), making it versatile for data processing.
Advantages
Flexibility:
The function can handle a wide range of scenarios, making it versatile for parsing text with various delimiters. It can handle both single and multiple pairs of delimiters, whether they are simple strings or complex regular expressions. This flexibility makes it suitable for different use cases.
Scalability:
It can parse multiple pairs of delimiters within a given text, which is especially useful when dealing with documents or data containing nested elements.
Pure Python:
It uses only Python's standard library
