Pythonic way to transform list of pairs to dict

Question

I have a List of pairs like this:

[
    {'Name': 'first_name', 'Value': 'Joe'},
    {'Name': 'last_name', 'Value': 'Smith'},
    {'Name': 'gender', 'Value': 'male'}
]

I want to transform it into a Dict like this:

{
    'first_name': 'Joe',
    'last_name': 'Smith',
    'gender': 'male'
}

I am currently using a simple loop to accomplish this now but I know there is a more Pythonic way to do it. Thoughts?

Answer 1

It was easier than I expected:

{pair['Name']:pair['Value'] for pair in source_list}

This uses a feature of Python called a Dict comprehension.

Answer 2

您可以在列表中的每个字典上使用values()方法的生成器输出实例化字典：

dict(d.values() for d in l)
