Creating a new pandas dataframe from shape

Question

I have information on total number of rows and number of columns for a new pandas dataframe

import pandas as pd
nRow = 10
nCol = 4

Based on this information I want to create a new dataframe where each element will be filled by 1

Is there any direct method available with pandas to achieve this?

Answer 1

Another possible solution, which uses np.ones to create an array of ones with which to create the wanted dataframe:

pd.DataFrame(np.ones((nRow,nCol)))
