如何在python中将文件读入字典

Question

我有以下格式的文本文件：

hsa04012 [[['7039', '1956', '1398', '25'], ['7039', '1956', '1399', '25']], [['1839', '1956', '1398', '25'], ['1839', '1956', '1399', '25']], [['1399', '25']], [['1398', '25']], [['727738', '1956', '1398', '25'], ['727738', '1956', '1399', '25']], [['1956', '1398', '25'], ['1956', '1399', '25']], [['1950', '1956', '1398', '25'], ['1950', '1956', '1399', '25']], [['374', '1956', '1398', '25'], ['374', '1956', '1399', '25']], [['2069', '1956', '1398', '25'], ['2069', '1956', '1399', '25']], [['685', '1956', '1398', '25'], ['685', '1956', '1399', '25']]]
hsa02331...

如何将文件读入字典，其中的键为包含hsa ...的文本，值为方括号内的数字（作为列表）。

Answer 1

我会使用str.split和ast.literal_eval 。 这似乎最简单...

with open(datafile) as f:
    d = {}
    for line in f:
        key,value = line.split(None,1)
        d[key] = ast.literal_eval(value)

虽然，您也许可以使用json玩一些游戏来获取列表。 列表被称为是非常有效的JSON数组。
