python - 如何将 Python 中 DataFrame 中的行转换为字典

Question

例如，我现在有 DataFrame

id score1   score2  score3  score4  score5
1  0.000000     0.108659    0.000000    0.078597    1
2  0.053238     0.308253    0.286353    0.446433    1
3  0.000000     0.083979    0.808983    0.233052    1

我想把它转换成

id scoreDict
1  {'1': 0, '2': 0.1086, ...}
2  {...}
3  {...}

无论如何要这样做？

import pandas as pd

# your df
# =========================
print(df)

   id  score1  score2  score3  score4  score5
0   1  0.0000  0.1087  0.0000  0.0786       1
1   2  0.0532  0.3083  0.2864  0.4464       1
2   3  0.0000  0.0840  0.8090  0.2331       1

# to_dict
# =========================
df.to_dict(orient='records')

Out[318]: 
[{'id': 1.0,
  'score1': 0.0,
  'score2': 0.10865899999999999,
