Python’s str.splitlines() Recognizes Extensive Unicode Line Boundaries
Python’s str.splitlines() splits strings on a comprehensive set of line boundaries, including Unicode control characters beyond standard newlines, affecting string parsing and processing.
- Python’s
str.splitlines()splits strings on a broad set of line boundaries, including\n,\r,\r\n, and additional Unicode separators such as\v,\f,\x1c,\x1d,\x1e,\x85,\u2028, and\u2029. - The method’s behavior exceeds the standard “universal newlines” definition, resulting in splitting at various control characters.
- Example:
'line1\nline2\rline3\r\nline4\vline5\x1dhello'.splitlines()yields['line1', 'line2', 'line3', 'line4', 'line5', 'hello'], demonstrating its extended boundary recognition.

The Hidden Challenge of Assessing Software Engineers’ Talent
The article discusses the difficulty in assessing software development talent externally due to legibility issues, emphasizing that highly skilled engineers often lack visible online activity, complicating hiring and promotion processes.
- Talented software engineers often remain invisible externally, with minimal online footprints and limited public contributions.
- Decision-makers struggle with a legibility problem, relying on observable but often ineffective indicators like LinkedIn profiles and GitHub activity.
- Industry evaluation methods tend to favor easily observable traits, risking the undervaluation of engineers working in less visible roles or companies.
