Question

I am seeing 5 items in each list below, but it looks like I am running into issues with the shape of my data when creating my dataframe. Any idea why this error is happening?

Code:

bet = pd.DataFrame(b)

b = {'Link':links, 'Tax':taxes, 'Description':descrip}
bet = pd.DataFrame(b)

It creates the DataFrame for me.

Answer 3

I don't understand what your problem exactly is, but if you just want to make a list into a dataframe, you can do this.

import pandas as pd

links = ['http://www.redfin.com/IL/Chicago/195-N-Harbor-Dr-60601/unit-509/home/14093313', 'http://www.redfin.com/IL/Chicago/1235-N-Astor-St-60610/unit-3N/home/13054822', 'http://www.redfin.com/MO/St-Louis/2622-S-11th-St-63118/home/93686930', 'http://www.redfin.com/IL/Chicago/426-W-Barry-Ave-60657/unit-408/home/13373863', 'http://www.redfin.com/IL/Chicago/310-S-Michigan-Ave-60604/unit-1608/home/45513284']
taxes = ['$631', '$859', '$377', '$201', '$575']
descrip = ['descript1', 'descript2', 'descript3', 'descript4', 'descript5']

b = {'Link':links, 'Tax':taxes, 'Description':descrip}
bet = pd.DataFrame(b)

if your problem is regarding this line of code inside of your error,

bet = pd.DataFrame(b, index=[1])

then you can change that into this

bet = pd.DataFrame([b], index=[1])
