Question

Sample Data
上面是我的示例文本文件，带有！作为分隔符

我希望数据表在Sqlite下查看此图像

Expected result 请我如何将这些数据插入python中的sqlite中，这是我的代码

问题：使用定界符读取文本文件...我希望将数据拆分为两个SQLITE表。

通过 line
读取文本文件 line
```
for line in f:
    ...
```

使用条件来确定哪个line进入哪个sqlite table。

if line is 'Matiyu 1':
    ...
elif line is '!Mattieu Chapitre 1':
    ...

将实际的line插入sqlite table
从 1。开始重复，直到读取文本文件中的所有行。

使用Python将带分隔符的文本文件读取到sqlite
