python dict to dataframe

http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.from_dict.html

Examples

By default the keys of the dict become the DataFrame columns:

>>> data = {'col_1': [3, 2, 1, 0], 'col_2': ['a', 'b', 'c', 'd']}

>>> pd.DataFrame.from_dict(data)

   col_1 col_2

0      3     a

1      2     b

2      1     c

3      0     d

Specify orient='index' to create the DataFrame using dictionary keys as rows:

>>> data = {'row_1': [3, 2, 1, 0], 'row_2': ['a', 'b', 'c', 'd']}

>>> pd.DataFrame.from_dict(data, orient='index')

       0  1  2  3

row_1  3  2  1  0

row_2  a  b  c  d

When using the ‘index’ orientation, the column names can be specified manually:

>>> pd.DataFrame.from_dict(data, orient='index',

...                        columns=['A', 'B', 'C', 'D'])

       A  B  C  D

row_1  3  2  1  0

row_2  a  b  c  d
