How to add column name from the pd.concat?

I am wondering is there any way to add column name from series of data.

I thought is something like this

std_df = pd.concat([q,w], axis=1, columns= ["apple","banana"])

But I get an error of concat() got an unexpected keyword argument 'columns'

I’ve tried names instead of columns, still not working.

>Solution :

pd.concat() has the keys parameter that will work for this purpose:

s1 = pd.Series([1,2,3])
s2 = pd.Series([4,5,6])

df = pd.concat([s1,s2],keys = ['A','B'],axis=1)

Output:

   A  B
0  1  4
1  2  5
2  3  6
