如何将具有多个值的列表转换为列表字典 [英] How to convert a list having multiple values into a dictionary of lists

问题描述

我有一个如下列表:

Lista =[('amazon', 'Amazon', 1.0), ('amazon', 'Alexa', 0.8), ('amazon', 'microsoft', 0.6), ('amazon', 'Amazon Pay', 0.7), ('amazon', 'Prime', 0.4),('alien', 'jack' , 0.0), ('alien', 'dell', 0.6), ('alien', 'apple', 0.0), ('alien', 'orange', 0.0), ('alien', 'fig', 0.0)]

现在，我正在执行基本检查，以查看哪些对的值大于0.0，然后将它们附加到如下所示的新列表中.

Now I am performing a basic check to see which pairs have value greater than 0.0 and then append them to a new list like below.

new_words = []

Lista =[('amazon', 'Amazon', 1.0), ('amazon', 'Alexa', 0.8), ('amazon', 'microsoft', 0.6), ('amazon', 'Amazon Pay', 0.7), ('amazon', 'Prime', 0.4),('alien', 'jack' , 0.0), ('alien', 'dell', 0.6), ('alien', 'apple', 0.0), ('alien', 'orange', 0.0), ('alien', 'fig', 0.0)]

for x in Lista:
    if x[2]>0:
    new_words.append(x[1])

我的问题是如何将结果附加到具有相应键，值对的字典中.所需的理想输出如下:(请注意，先前的new_words是一个列表，但现在在理想输出中我希望将其作为字典)

My question is how do I append the results in a dictionary with respective key, value pairs. Ideal output required is as below: (Please note earlier new_words was a list but now in the ideal output I want it as a dictionary)

new_words={'amazon': ['Amazon', 'Alexa', 'microsoft', 'Amazon Pay', 'Prime'],
 'alien': ['dell']}

推荐答案

您无法在字典中获得所需的结果，因为字典中不包含重复的键(类似于普通的英语词典:其中的单词可能拼写相同，但发音有所不同.

You can't have the desired result in a dictionary as dictionaries don't contain duplicate keys (similar to a normal English dictionary: where the words might spell the same but there are differences in pronunciation).

所需结果可以再次存储到列表中.

The desired result can be stored again into a list.

newDict = {}
result = []

Lista =[('amazon', 'Amazon', 1.0), ('amazon', 'Alexa', 0.8), ('amazon', 'microsoft', 0.6), ('amazon', 'Amazon Pay', 0.7), ('amazon', 'Prime', 0.4),('alien', 'jack' , 0.0), ('alien', 'dell', 0.6), ('alien', 'apple', 0.0), ('alien', 'orange', 0.0), ('alien', 'fig', 0.0)]

for items in Lista:
    if items[2] > 0.0:
        newDict[items[0]] = items[1]
        result.append(newDict)
        newDict = {}

print result
