我试图打印序列,但得到了键错误?在python中

您现在位置:Python中文网/ 问答频道 /正文

我只得到了第一个输入文件正确的输出,但是我在第一个文件中有一个,B,C,D链,并且得到了正确的输出,在这种情况下,在第二个输入文件中没有C和D链在这种情况下,我们的代码复制了C和D的第一个文件数据的相同数据。?我也不能增加这个id:chainIDs=['A','B','C','D']

我想搜索A到Z链ID,如果我替换为chaineids=['A','B','C','D']to chainIDs=['A','B','C','D','F','G','H']。在

若输入文件中不存在任何链id,则代码只需忽略并为其他人继续。在

显示错误:

f.write(d[chainID][atomIDs[i+j]]+ '\n')  
KeyError: 'E'

脚本:

^{pr2}$

只需将输出循环更改为如下所示:

for chainID in chainIDs:
    if chainID in d:
        for atom_id in d[chainID]:
            with open(filenames+'out.pdb', 'a') as f:
                f.write(d[chainID][atom_id] + '\n')
