print() # Print a newline at the end of the row. 这些嵌套的for循环确保我们将一整行单元格打印到屏幕上,并在行尾跟随一个换行符。我们对nextCells中的每一行重复这一过程。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 # Calculate the next step's cells based on current step's cells: fo...

执行从/path/to/filename.zip中提取的__main__.py中的代码。 Zip 是一种面向端的格式:元数据和指向数据的指针都在末尾。这意味着向 zip 文件添加前缀不会改变其内容。 因此,如果我们获取一个 zip 文件,并给它加上前缀#!/usr/bin/python<newline>,并将其标记为可执行,那么当运行它时,Python 将会运行一个...

The backlash in Python (outside the string) allows you to continue your line of code into the next line. The main drawback of this approach is that you have to add the backslash to the end of every line in addition to the '\n' character, which can get very tedious. ...

如果您正在尝试上述代码,您可以对Polygon进行子类化,并覆盖__init__函数,而不是替换初始化器或复制add_point和perimeter方法。 然而,在面向对象和更注重数据的版本之间没有明显的赢家。它们都做同样的事情。如果我们有新的函数接受多边形参数,比如area(polygon)或point_in_polygon(polygon, x, y),面向对象代码的好处...
三Multi-line statement In Python, the end of a statement is marked by a newline character. But we can make a statement extend over multiple lines with the line continuation character `\`. 默认情况下,Python 中一条语句的结束是由“换行符”(即回车键)决定的: ...
