python - Convert a dictionary to a pandas dataframe

I'm trying to convert a dictionary that only has 1 record to a pandas dataframe. I've used the following code from other solutions:

d =  {'id': 'CS2_056', 'cost': 2, 'name': 'Tap'}

pd.DataFrame(d.items(), columns=['id', 'cost','name'])

But I get the following error:

PandasError: DataFrame constructor not properly called!

You dict has only one record use list:

import pandas as pd
d =  {'id': 'CS2_056', 'cost': 2, 'name': 'Tap'}
df = pd.DataFrame([d], columns=d.keys())
print df

Output:

   id  cost name
0  CS2_056     2  Tap
