Create pandas dataframe manually without columns name

Question

I would like to create the following dataframe without columns names

import pandas as pd
df = pd.DataFrame([0,423,2342],[12,123,1231], [1,3,5])

I get back an error

TypeError: unhashable type: 'list'

What am I doing wrong?

I also tried {}, but it did not help.

df = pd.DataFrame({[0,423,2342],[12,123,1231], [1,3,5]})

The thing is you should pass your data as a 2D array, otherwise the constructor thinks you've passed several positional arguments.

DataFrame([[0,423,2342],[12,123,1231], [1,3,5]])

Technically, this is a list of lists. – chthonicdaemon Aug 18 '15 at 17:20
@chthonicdaemon Yes, technically it's a nested list that is isomorphic to 2D array. – Eli Korvigo Aug 18 '15 at 17:22
