Python- How to Combine 2 pandas.core.frame =.dataframe with the same column name together in python [duplicate]

Question

So i got 2 pandas.core.frame.DataFrame like this:

anomalies:

             Sales  outlet
Date                     
2006-07-01    700       2

and this (anomalies2):

            Sales  outlet
Date                     
2011-03-01    206       1
2012-03-01    900       1

i tried combining them using :

anomalies3 = []
anomalies3.append(anomalies)
anomalies3.append(anomalies2)
print(anomalies3)

but the result are like this:

[            Sales  outlet
Date                     
2006-07-01    700       2,             Sales  outlet
Date                     
2011-03-01    206       1
2012-03-01    900       1]

how do i make it so the result were like

[            Sales  outlet
Date                     
2006-07-01    700       2                    
2011-03-01    206       1
2012-03-01    900       1]

Thanks in advance! and remember both are pandas.core.frame.DataFrame (type(anomalies) and type(anomalies2) give back pandas.core.frame.DataFrame)

Answer 1

just use

anomalies3 = pd.concat([anomalies, anomalies2])
