Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
API requires Python-specific patterns, such as context managers and decorators, which may be unfamiliar to those without extensive Python experience.
Historical updates from v0.1 to v0.2 and beyond have introduced significant API changes, requiring substantial code refactoring for existing projects.
Being a Python-specific library means that it does not integrate easily with other languages or frameworks without additional development effort.
Setting up syntax highlighting, auto-completion, and multi-line inputs requires significant configuration and understanding of the library's architecture.
