Because Python is an interpreted language, its syntax is more concise than Java, making getting started easier and testing programs on the fly quick and easy. You can enter lines right in the terminal, where Java needs to compile the whole program in order to run. Type python and then 3+...
The order of learning a programming language is not a problem. You can learn Java first and then Python. It only depends on the amount of time and energy that you invest. However, if you can learn Python first, then it will simplify learning Java. That’s because learning Python will bo...

另外,一直被Ruby开发者所认为的Python不够OO的一个例子就是取一个序列的长度,Python使用len(x)的方法。这个问题,如果Ruby开发者认为x.length就可以算是OO的话,那么Python也大可以直接使用x.__len__()来获取长度。从用方法来封装属性的Java角度讲,谁更OO一些呢,哈哈。
