将带有字典子列表的字典转换为 pandas dataframe

Question

I have this code with a dictionary "dict":

import pandas as pd

dict = {
    '2000': [{'team': 'Manchester United', 'points': '91'}],
    '2001': [{'team': 'Manchester United', 'points': '80'}],
    '2002': [{'team': 'Arsenal', 'points': '87'}]
}

df = pd.DataFrame.from_dict(dict, orient='index')
print(df)

The result is:

                                                 0
2000  {'team': 'Manchester United', 'points': '91'}
2001  {'team': 'Manchester United', 'points': '80'}
2002            {'team': 'Arsenal', 'points': '87'}

But what I want is:

        team                  points
2000    Manchester United     91
2001    Manchester United     80
2002    Arsenal               87

I would like to obtain this, without using loops in python, and by using pandas. Can anyone help me out?

Thanks in advance!

Tr this. This would depend on how large your data is.

diction =  {
    '2000': [{'team': 'Manchester United', 'points': '91'}],
    '2001': [{'team': 'Manchester United', 'points': '80'}],
    '2002': [{'team': 'Arsenal', 'points': '87'}]
}
transformed_dict= {x:d for x,y in diction.items() for d in y }
df = pd.DataFrame(transformed_dict)
df.T
