Python Pandas DataFrame with only a single number stored?

Question

AzureML's Python Script module requires to return a Pandas DataFrame. I want to return only a value and I do this:

result=7

dataframe1=pd.DataFrame(numpy.zeros(1))

dataframe1[0][0]=result

by which I am able to return just a single value in Azure ML's Python Script module.

What is a proper way to create a pandas DataFrame with a single value?

Answer 1

The code below should work:

import pandas as pd

def azureml_main(dataframe1 = None, dataframe2 = None):

    result = pd.DataFrame({'mycol': [123]})

    return result,
