Question

我正在尝试从3个列表中创建一个字典，其中一个是嵌套列表。

Companies = ['Company A', 'Company B']
features = ['Feature 1', 'Feature 2', 'Feature 3']
values = [['On', 'Off', 'On'], ['Off', 'On', 'Off']]

# This is what i would like the out put to look like, any help would be great 

results = {{'Company A': {'Feature 1' : 'On', 'Feature 2': 'Off', 'Feature 
3': 'On'}, 'Company B': {'Feature 1' : 'Off', 'Feature 2': 'On', 'Feature 
3': 'Off'}}}

Answer 1

Companies = ['Company A', 'Company B']
features = ['Feature 1', 'Feature 2', 'Feature 3']
values = [['On', 'Off', 'On'], ['Off', 'On', 'Off']]
results = {}

for i in range(len(Companies)):
    results[Companies[i]] = dict(zip(features,values[i]))

print (results)

输出：

{“公司A”：{“功能3”：“开启”，“功能2”：“关闭”，“功能1”：“开启”}，“公司B”：{“功能3”：“关闭”，“功能2”：“打开”，“功能1”：“关闭”}}

Answer 2

您可以使用字典理解：

results = {comp: {feat: v for feat,v in zip(features,val)} for comp,val in zip(Companies,values)}

输出：

{'Company A': {'Feature 1': 'On', 'Feature 2': 'Off', 'Feature 3': 'On'}, 'Company B': {'Feature 1': 'Off', 'Feature 2': 'On', 'Feature 3': 'Off'}}
