想从NCBI中批量获取一些基因组信息，运行Python后提示“AttributeError: 'NoneType' object has no attribute 'group' 怎么修改啊？

我目前有许多基因ID，想从NCBI
（https://www.ncbi.nlm.nih.gov/assem
中批量搜索这些基因的相关信息，形成文件。
获取信息部分内容如下

基因ID：GCF_002583515.1，GCF_002560475.1，GCF_002566665.1，GCF_002552335.1，GCF_000293525.1，GCF_002567745.1

从网上看了一些别人编的代码
我运行后提示：
