Introduction

lab00

wget https://cs61a.org/lab/lab00/lab00.zip
unzip lab00.zip

实验目录下有如下文件：

$ ls
__pycache__  lab00.ok  lab00.py  ok  tests

下面是解释：

  • lab00.py: the starter file you just edited
  • ok: our testing program
  • lab00.ok: a configuration file for Ok

关于 ok 的命令生成器：

okpy Command Generator

lab00 要求很简单：

def twenty_twenty_two():
    """Come up with the most creative expression that evaluates to 2022,
    using only numbers and the +, *, and - operators.

    >>> twenty_twenty_two()
    2022
    """
    return 2022

用表达式返回值 2022 即可，这里我就直接返回了😸。

python3 ok

执行，如果想submit，可以换成 python3 ok submit 。
