GC(Garbage Collection) 是目前很多编程语言自带的特性,例如Java,Python;GC是一个很好的特性,能让使用这个语言编程的程序员不去关心内存回收,并且降低内存泄漏和内存溢出发生的概率。
Everything you Should Know About Data Structures in Python Key Takeaways We learned the difference between Object-oriented programming and procedure-oriented programming. The two main aspects of OOPs are class and object. The four principles of OOPs are Inheritance, Polymorphism, Encapsulation, and Ab...
