使用嵌套列表创建字典，其中第一个列表是列，每个列表是一行？

Question

I have a nested loop that has the first list as column names and each subsequent list is a row. For example, I have a nested list that gives a person's age and 1 or 0 indicating whether or not they like the color:

data = [['age', 'blue', 'green', 'red', 'orange'], 
         [12, 1, 0, 0, 1],
         [10, 0, 1, 0, 1],
         [9, 0, 0, 0, 0],
         [8, 1, 0, 0, 0],
         [13, 1, 1, 1, 0]

I want an output that looks like:

 new_data ={(12, 'blue'): 1,
            (12, 'green'): 0,
            (12, 'red'): 0,
            (12, 'orange'): 1,
            (9, 'blue'): 0,
            (9, 'green'): 1,
            (9, 'red'): 0,
            (9, 'orange'): 1 .....}

etc but with all data.

I've gotten as far as:

ages = data[0][1:len(data[0])]

i = 1
for x in ages:
    print({t[0] + x: t[i] for t in data[1:len(data)]})
    i = i + 1

and when I try to combine t[0] and x as a tuple it ends up only giving me:

{'12blue': 1, '10blue': 0, '9blue': 0, '8blue': 1, '13blue': 1}
{'12green': 0, '10green': 1, '9green': 0, '8green': 0, '13green': 1} 

etc.

Answer 1

You could do the following:

import pprint

data = [['age', 'blue', 'green', 'red', 'orange'],
        [12, 1, 0, 0, 1],
        [10, 0, 1, 0, 1],
        [9, 0, 0, 0, 0],
        [8, 1, 0, 0, 0],
        [13, 1, 1, 1, 0]]

colors, *rows = data # split in colors and rows

d = {}
for row in rows: 
    idi, *marks = row # split in id and marks
    for color, mark in zip(colors[1:], marks): # iterate in parallel over marks and colors
            d[(idi, color)] = mark


pprint.pprint(d)

Output

{(8, 'blue'): 1,
 (8, 'green'): 0,
 (8, 'orange'): 0,
 (8, 'red'): 0,
 (9, 'blue'): 0,
 (9, 'green'): 0,
 (9, 'orange'): 0,
 (9, 'red'): 0,
 (10, 'blue'): 0,
 (10, 'green'): 1,
 (10, 'orange'): 1,
 (10, 'red'): 0,
 (12, 'blue'): 1,
 (12, 'green'): 0,
 (12, 'orange'): 1,
 (12, 'red'): 0,
 (13, 'blue'): 1,
 (13, 'green'): 1,
 (13, 'orange'): 0,
 (13, 'red'): 1}
