Connection through python script

Following instructions from here https://docs.microsoft.com/en-us/power-bi/desktop-python-scripts

I can run the following python code and generate data.

 

import pandas as pd data = [['Alex',10],['Bob',12],['Clarke',13]]
df = pd.DataFrame(data,columns=['Name','Age'],dtype=float)
print (df)

 

 

I contructed same df in a class - created a package named Mypackage

 

import pandas as pd
class Mydata:
    def __init__(self):
    pass

    def main_page(self):
    data = [['Alex',10],['Bob',12],['Clarke',13]]
    df = pd.DataFrame(data,columns=['Name','Age'],dtype=float)
    return df

 

 

Now when I call the data, nothing is returned

 

from Mypackage import MyData
df = Mydata().main_page()
print(df)

 

 

If I try 

 

from Mypackage import MyData
df = Mydata().main_page()
print(df.head())

 

 

 Then I get the following error

 

Unable to connect
Details: "ADO.NET: Python script error.
Traceback (most recent call last):
  File "PythonScriptWrapper.PY", line 13, in <module>
    print(df.head())
AttributeError: 'NoneType' object has no attribute 'head'
"

Hi @vasimnps ,

What the version of Python do you install? If you use 3.7, please install Python 3.6 to have a try. And make sure you have installed Pandas package.

Thank you very much @v-xuding-msft 

 

V3.6 did the trick, any reason why so?
