I want to start with an empty data frame and then add to it one row each time. I can even start with a 0 data frame data=pd.DataFrame(np.zeros(shape=(10,2)),column=[\
data=pd.DataFrame(np.zeros(shape=(10,2)),column=[\
If you are replacing the entire row then you can just use an index and not need row,column slices. ...
data.loc[2]=5,6
