Many modern programming languages implement bounds checking automatically.

许多现代编程语言自动实现边界检查。

Modern programming languages come with huge bundles of pre-written functions, called Libraries.

现代编程语言带有大量预写函数，称为库。

If you understand this example, then you understand the power of functions, and the entire essence of modern programming.

如果你理解了这个例子，那么你就会理解函数的力量，以及现代编程的全部本质。

Sadly, there are no surviving examples of A-0 code, so we'll use Python, a modern programming language, as an example.

遗憾的是，没有现存的 A-0 代码示例，因此我们将使用现代编程语言 Python 作为示例。

In modern programming, it's uncommon to see functions longer than around 100 lines of code, because by then, there's probably something that should be pulled out and made into its own function.

在现代编程中， 很少会看到超过 100 行代码的函数，因为到那时， 可能有一些东西应该被提取出来并放入它自己的函数中。
