python - 将 dictreader 转换为字典字典的优雅方法

Question

我正在这样做:

headers = ['name', 'accum', 'hi', 'active', 'first', 'last', 'max', 'dirty']
filename = "C:\\Users\\bcrafton\\Desktop\\se0sh0cb0_perf.vec"

with open("C:\\Users\\bcrafton\\Desktop\\se0sh0cb0_perf.vec") as csvfile:

    for line in csvfile:
        if all(header in line for header in headers):
            reader = csv.DictReader(csvfile, fieldnames=headers)
            break

效果很好。

但我不想为了使用我的数据而保持文件打开。有没有优雅的方法，将我的数据放入 RAM，而不需要打开文件？

理想情况下，我希望能够关闭文件，然后能够访问我的数据，执行类似的操作

table['name']['address']

尽管您遗漏了一些基本细节，但我还是做了一些假设:

table = {}

with open("C:\\Users\\bcrafton\\Desktop\\se0sh0cb0_perf.vec") as csvfile:
    for line in csvfile:
        if all(header in line for header in headers):
            for row in csv.DictReader(csvfile, fieldnames=headers):
                name_row = table.get(row['name'], {})
                name_row[row['name']] = row['address']
