这一章我们实现男子和女子30米x2蛇形跑成绩的计算，单位是数值，多少秒，全年龄段考核内容都是30米x2蛇形跑，相对也简单。

一、基本情况

通过分析男女30米x2蛇形跑“成绩计算标准表”，发现标准表也只是参照标准表，不是连续的全覆盖。比如标准中24岁以下，只规定了男子蛇形跑18.1秒的成绩为100分，18.7秒的成绩为95分，那么中间的情况多少分呢？

还是只能是我们根据公平原则去补充，在18.1秒、18.7秒的成绩之间去取平均分，数据量比较小，NO！数据量不算小，也不大，看下图就知道！

这时我也想到3公里测试的原始成绩跨度更大，使用这种手工添加补充的办法已经落后了，不过新算法再酝酿当中，也不复杂。本次我也选择手工计算，补充到成绩计算标准表里，精确到小数点后一位。

同样，通过Python的openpyxl模块读取补充成绩计算标准表中的数据，制成 {原始蛇形跑时长：分数} 格式的字典，以供主程序查询出换算成绩，再写入成绩表的对应位置中。

二、代码实现

1.我把计算男子和女子蛇形跑的文件分开，分别放入单独的模块中，男子的文件命名为serpentine_run_male.py。因为男女蛇形跑读取不同的工作簿中的标准表，分开做也方便。计算函数的原理与前面的文章相同，增加了一项判定，若原始数据类型不是整型和浮点型，则不执行计算，打印错误。

2.女子仰卧起坐的文件命名为serpentine_run_female.py，除了读取的工作簿不同，其它内容与男子大体相同。只是在参照标准编写程序时要特别细心，设置临界数值时不能出错，比如24岁以下女子大于22.6秒0分，20秒100分，但是25岁~27岁是大于22.9秒0分，20.3秒100分。这种变化也可以通过编程实现自动化计算，虽变化次数不多，但设计算法的复杂度会增加很多，这里有改进的空间，可以探索。一切相似重复的代码段都可以使用函数替代吧。

3.对主程序training_performance.py进行修改，判断性别后，先计算单杠成绩，接着计算仰卧起坐成绩，再计算蛇形跑成绩，写入表中换算成绩的相应位置。

wb.save('计算结果.xlsx')

运行后，生成文件“计算结果.xlsx”如下：
蛇形跑计算结果

到此，我们成功实现了男女仰卧起坐成绩计算的功能。
