如何从python中的字典创建字典？

Question

Date        Subject     Maths  Science English French  Spanish German
16:00:00    Uploaded      100    95      65      32      23      45

我的文本文件dataVal.txt中有这两个表。

我希望输出像：

'Subject'：'Uploaded'：'16:00:00'：'Maths'：'100'，Science :: 95 ....诸如此类。 基本上，“主题”是第一个表的主键，该表的值为“ Uploaded”，然后“ Uploaded”成为值为“ 16:00:00”的键，然后成为键并具有Maths ，科学，英语等，其进一步的值分别为100、95、65等。

dic = dict()
with open('C:\\Users\\aman.seth\\Documents\\dataVal.txt','r') as fh:
    for l in fh.readlines():
        try:
            lines = l.split('\t')
            date, sub, num = lines[0], lines[1], [str(x) for x in lines[2:]]
            dic.setdefault(sub, {})
            dic[sub][date] = num
        except Exception as er:
            print er
print dic

到目前为止，这是我所做的，但是我猜这还不够准确。

请尝试此操作，并进行修复：

import re

dic = dict()

with open('txt', 'r') as fh:
    memory = None
    for line in fh.readlines():
        lines = line.rstrip('\n')
        if line.split():
            try:
                match = re.search('(BoardType|Subject)', line)
                if match:
                    memory = match.group(1)
                    dic.setdefault(memory, {})
                    header = line.split()
                    mark_index = header[2:]
                else:
                    mark_dict = dict()
                    lines = [ x for x in line.split(' ') if x]
                    date, sub, num = lines[0], lines[1], [str(x) for x in lines[2:]]
                    dic[memory].setdefault(sub, {})
                    mark = dict(zip(mark_index, num))
                    dic[memory][sub][date] = mark
            except Exception as error:
                print 'Error: ', error
import pprint
pprint.pprint(dic)

输出：
