Examples
The keys of the dict become the DataFrame columns by default:

import numpy as np
import pandas as pd

data = {'c_1': [4, 3, 2, 0], 'c_2': ['p', 'q', 'r', 's']}
pd.DataFrame.from_dict(data)

	c_1	c_2
0	4	p
1	3	q
2	2	r
3	0	s

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

data = {'row_1': [4, 3, 2, 0], 'row_2': ['p', 'q', 'r', 's']}
pd.DataFrame.from_dict(data, orient='index')

	0	1	2	3
row_1	4	3	2	0
row_2	p	q	r	s

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

pd.DataFrame.from_dict(data, orient='index',
                       columns=['P', 'Q', 'R', 'S'])

	P	Q	R	S
row_1	4	3	2	0
row_2	p	q	r	s
