python - 我如何打印一些东西然后打印它的列表？

Question

我有一个 txt 文件，其中包含世界上所有国家及其导出的产品类型。

这是一行没有任何拆分或剥离的样子(注意 \t 和 \n):[牙买加氧化铝、铝土矿、糖、朗姆酒、咖啡、山药、饮料、化学品、服装、矿物燃料\n]

我必须编写一个程序来执行此操作:

Angola
[ 'oil,', 'diamonds,', 'refined', 'petroleum', 'products,', 'coffee,', 'sisal,', 'fish,', 'fish', 'products,', 'timber,', 'cotton']

Anguilla
[ 'lobster,', 'fish,', 'livestock,', 'salt,', 'concrete', 'blocks,', 'rum']

Antigua and Barbuda
[ 'petroleum', 'products,', 'bedding,', 'handicrafts,', 'electronic', 'components,', 'transport', 'equipment,', 'food,', 'live', 'animals']

Argentina
[ 'soybeans,', 'petroleum,', 'gas,', 'vehicles,', 'corn,', 'wheat']

这是我到目前为止所做的，但从现在开始我不知道如何前进:

import os
file=open("exports.txt",'r')
list=[]

for i in file:
    list.append(i.split(" "))

for i in range(len(list)):
    print(list[i])

结果我得到了每个国家的列表以及它导出什么:

['Angola\t', 'oil,', 'diamonds,', 'refined', 'petroleum', 'products,', 'coffee,', 'sisal,', 'fish,', 'fish', 'products,', 'timber,', 'cotton\n']
['Anguilla\t', 'lobster,', 'fish,', 'livestock,', 'salt,', 'concrete', 'blocks,', 'rum\n']
['Antigua', 'and', 'Barbuda\t', 'petroleum', 'products,', 'bedding,', 'handicrafts,', 'electronic', 'components,', 'transport', 'equipment,', 'food,', 'live', 'animals\n']
['Argentina\t', 'soybeans,', 'petroleum,', 'gas,', 'vehicles,', 'corn,', 'wheat\n']

我该如何继续？感谢帮助

应该这样做

with open("exports.txt",'r') as infile:
    exports = {}
    for line in infile:
        parts = line.partition('\t')
        exports[parts[0]] = parts[-1].strip().split(', ')

for country, exports in exports.iteritems():
    print country
    print exports
