Question:

What is the advantage of Python over Java?

Inactive
Khang D.
Answer:

- Python does not require the use of semicolons, parentheses (except for PRINT statements), curly braces and instead opt for indentation as a form of block identification. - Python is a dynamically-typed language, which dictates that the types of variables are assumed at runtime. For example, a simple variable can be declared and initialized as so a = 5 b = "string" - It is also much simpler than Java due to its syntax which does not require a lot of overhead.

Java prohibits generic array since, at runtime, an array must contain the information on the class of its component.

Question:

What is the main advantage of passing arguments by reference? How is it useful?

Inactive
Khang D.
Answer:

Passing arguments by reference can change the value of the argument and retain that change after a function has exited. This can also be useful in the fact that since there is no extra copy of a large object is made, the program can be executed faster than the case in which passing by value is used.
