ValueError: Buffer dtype mismatch, expected 'Python object' but got 'long long' - MaJeFi - Mar-12-2019
I am new to Python. I got the error message in the title which is meaningless to me when my program got to the following line:
dfTemp = pd.concat([tenderers, newTenderer], axis=1)I am trying to join two dataframes on the vertical axis. Could someone either tell me what I am doing wrong or if there is another way of achieving my goal, please?

What data frames are defined under
tenderers and newTenderer ? tenderers.info()?To do vertical concatenation you need to pass
axis=0 instead:# short example import pandas as pd x = pd.DataFrame(pd.np.random.rand(10,10)) pd.concat([x, x], axis=0)

scidam,
Thank you very much! That seems to have fixed my problem. I can now move on to my next one.
