`data/1.python初阶/1.预备知识/1.Python简介/config.json` 里配置对该知识节点导出的习题 + +```json +{ + // ... + "export": [ + "helloworld.json" + // ... + ] +} +``` + +其中`"helloworld.json"`是习题的配置文件，文件如下： +```json +{ + "exercise_id": 33, + "source": "helloworld.py", + "depends": [], + "multiline": [ + { + "str1 = \"Hello,\"": "", + "str2 = \"World!\"": "str = \"Hello,World!\"", + "print('str1'+'str2')": "print(str)" + }, + { + "str1 = \"Hello,\"": "", + "str2 = \"World!\"": "", + "print('str1'+'str2')": "print(\"Hello\" +\",\" +\"World!\")" + }, + { + "print('str1'+'str2')": "print(str1+str2)" + } + ] +} +``` + +其中： + +* `"exercise_id"` 是脚本填充的字段，编辑的时候不用填写 +* `"source"` 指定了习题的来源文件 +* `"depends"`: 指定了习题依赖的同知识点下的其他源文件 +* `"multiline"`: 是习题选项替换的规则之一 + + +#### 习题源代码 + +`"helloworld.py"`的源代码如下： + +```python +# -*- coding: UTF-8 -*- +# 作者：幻灰龙 +# 标题：Hello World +# 描述：输出 "Hello,World!" 字符串，找出错的那项。 + +if __name__ == '__main__': + str1 = "Hello," + str2 = "World!" + print('str1'+'str2') + +``` + +源代码的头部注释固定格式，配置`作者`,`标题`,`描述`，其中描述可以是MarkDown格式 + +#### 习题源代码替换规则 + +对于习题代码 `"helloworld.py"` 的代码变种替换规则配置在`"helloworld.json"` 里面。有两种替换规则： + +**单行替换规则**： + +* 配置由`one_line`字段指定的单行替换字典 +* 格式是：`"<源字符串>"`: [`"<替换字符串A>"`, `<替换字符串B>`,...], + * 其中每个 `"<源字符串>"` `/` `"<替换字符串A>"` 被生成为是一个替换选项 + * 指定的配置应该能至少生成 `3+` 个替换选项 + +```json +{ + "one_line": { + "printf": ["print"], + "return 0;": ["return 0"], + "(\"Hello,Wrold!\")": [" \"Hello,Wrold!\""] + } +} +``` + +上面的替换规则会将代码替换成 3 个变种的代码： + +```c +// 变种代码1 +#include +int main(int argc, char** argv){ + print("Hello,Wrold!"); + return 0; +} +``` + +```c +// 变种代码2 +#include +int main(int argc, char** argv){ + print("Hello,Wrold!"); + return 0 +} +``` + +```c +// 变种代码3 +#include +int main(int argc, char** argv){ + print "Hello,Wrold!"; + return 0 +} +``` + +这些变种代码将会作为技能树该知识点该代码选择题的选项。 + +**多行替换规则**： + +* 配置由`multiline`字段指定的多行替换数组 +* 数组的每个元素是一组替换规则，会整组被替换 + +例如： + +```json +{ + "multiline": [ + { + "printf": "print" + }, + { + "int main(int argc, char** argv){" : "int main(char** argv){", + "return 0;" : "return 0", + }, + { + "#include ": "" + } + ] +} +``` + +同样，该配置将支持将源代码生成3个变种代码 + +```c +// 变种代码1 +#include +int main(int argc, char** argv){ + print("Hello,Wrold!"); + return 0; +} +``` + +```c +// 变种代码2, 注意第2组替换规则，包含了两行替换 +#include +int main(char** argv){ + print("Hello,Wrold!"); + return 0 +} +``` + +```c +// 变种代码3 +int main(int argc, char** argv){ + print("Hello,Wrold!"); + return 0; +} +``` + +## `知识节点` 的习题配置规则(二) + +另外一种更便利的配置习题的方式是直接基于 MarkDown 格式配置。还是以`"helloworld.json"` 为例子展开描述。 + +此时，`"helloworld.json"` 简化为： + +```json +{ + "type": "code_options", + "author": "幻灰龙", + "source": "helloworld.md", +} +``` + +其中 type 字段目前都固定是 `code_options`。根据具体情况写好其它字段，注意这里 `source` 的文件名，我们指定了一个 Markdown 文件。现在我们新建一个 `helloworld.md` 并编辑为： + +````markdown +# Hello World + +输出 "Hello,World!" 字符串，找出错的那项。 + +## 答案 + +```python +if __name__ == '__main__': + str1 = "Hello," + str2 = "World!" + print('str1'+'str2') +``` + +## 选项 + +### 两字符串变量拼接 + +```python +if __name__ == '__main__': + str1 = "Hello," + str2 = "World!" + print(str1+str2) +``` + +### 两字符串字面量拼接 + +```python +if __name__ == '__main__': + print("Hello,"+"World!") +``` + +### 两字符串字面量拼接成字符串变量 + +```python +if __name__ == '__main__': + str = "Hello," + "World!" + print(str) +``` + +```` + +这是一个最基本的习题结构，它包含标题、答案、选项，注意这几个一级和二级标题必须填写正确，解释器会读取这几个标题。而选项的标题会被直接忽略掉，在 +最终生成的习题中不包含选项的三级标题，所以这个标题可以用来标注一些编辑信息，例如“此选项没有关闭文件连接”，“类型错误”等等。 + +## 习题配置规则的选择 + +我们介绍了两种习题编辑规则，目前Python技能树这里大量使用了规则(一)，这是历史编辑遗留。新增习题建议使用规则（二），更简洁方便。 + +## 技能树合成 + +在根目录下执行 `python main.py` 会合成技能树文件，合成的技能树文件: `data/tree.json` + +* 合成过程中，会自动检查每个目录下 `config.json` 里的 `node_id` 是否存在，不存在则生成 +* 合成过程中，会自动检查每个知识点目录下 `config.json` 里的 `export` 里导出的习题配置，检查是否存在`exercise_id` 字段，如果不存在则生成 diff --git
