Convert from list to list of dicts

Question

I have the following list

a = ['Bananas', 'Ananas', 'Peach', 'Grapes', 'Oranges']

and want to have it as a list of dicts like

b = [{"fruit": "Bananas"},{"fruit": "Ananas"},{"fruit": "Peach"},{"fruit": "Grapes"},{"fruit": "Oranges"}]

How can that be done?

Answer 1

你可以这样做： b = [{'fruit':f} for f in a]

Answer 2

These are actually dictionaries not sets inside the list, you can give a try to list comprehension:

a = ['Bananas', 'Ananas', 'Peach', 'Grapes', 'Oranges']
b = [{"fruit": x} for x in a]
print(b)

Answer 3

如果你想有一个关键的fruit ，你应该使用列表理解：

b = [{ 'fruit': x } for x in a ]
