Greg ewing has created a language called pyrex , which melds python and c . in particular , to use pyrex , you write functions in a python - like language that adds type - declarations to selected variables 特別地,要使用pyrex ,需要用類似python的語言編寫函數,這種語言將類型聲明添加到所選變量中。
The fact that java , unlike python , has type - declarations is actually less significant than many people assume but prior work in optimization of self , smalltalk , lisp , and scheme make this point also Java不像python ,它有類型聲明,但這一事實實際上沒有許多人所設想的那樣重要(但是先前在self 、 smalltalk 、 lisp和scheme的優化方面所做的工作也說明了這一點) 。
