Joining same-key dictionaries into a dataframe in pandas
提问by Anton Tarasenko
How to create a pandas DataFrameout of two and more dictionaries having common keys? That is, to convert
如何DataFrame从两个或更多具有公共键的字典中创建一个Pandas？也就是说，要转换
d1 = {'a': 1}
d2 = {'a': 3}
...
into a dataframe with columns ['d1', 'd2', ...], rows indexed like "a"and values determined by the respective dictionaries?
到一个数据帧中，列['d1', 'd2', ...]，行索引，"a"以及由各自字典确定的值？
采纳答案by unutbu
import pandas as pd
d1 = {'a': 1, 'b':2}
d2 = {'a': 3, 'b':5}
df = pd.DataFrame([d1, d2]).T
df.columns = ['d{}'.format(i) for i, col in enumerate(df, 1)]
yields
产量
In [40]: df
Out[40]:
d1 d2
a 1 3
b 2 5
