Python:对多个dicts TypeError:“str”对象不支持项赋值

Question

这是我的密码

sample_fh = dir + "sampleManifest.txt"
kids = {}
fid = {}
parents = {}
status = {}
sex = {}
with open(sample_fh) as f:
    for line in f:
            line = line.rstrip('\n')
            row = line.split('\t')
            fid = row[0]
            iid = row[1]
            relation  = row[5]
            status = row[6]
            sex = row[7]
            if relation != "Mother" and relation != "Father":
                    kids[iid] = 1
                    status[iid] = status
                    fid[iid] = fid
                    sex[iid]= row[7]
            if relation == "Mother" or relation == "Father":
                    parents[(fid,relation)]  = iid

我得到这个错误：

不知道发生了什么事。以前的论坛说这个错误是由于你改变了字符串，但我很确定我没有改变任何字符串。在

在代码status = row[6]中重新分配status，这样它就不再是dict了，要么为dict使用另一个名称，要么更改循环中的状态，只是不要同时使用它。在

status = {} # starts as a dict
status = row[6] # now the name status points to something else i.e a str
