Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
The library is exclusively available in Python, which can be a limitation for projects that use other languages.
While the basic API is well-documented, detailed explanations and examples for more complex operations are lacking.
The library can become slow when processing extremely large sequences or datasets due to computational complexity of string distance algorithms.
