concatenate dataframe with dataframe from list

I want to concatenate a dataframe (df) with another dataframe that is stored in a list of dataframes.

dflist = [df1, df2, df3]

What I want is a dataframe like below

new_dflist = [df+df1, df+df2, df+df3]

new_dflist=[]
for n in dflist:
    new_dflist.append(pd.concat(df, dflist[n]))

but I get the error,
TypeError: list indices must be integers or slices, not DataFrame

I also tried with enumerate but I get the error,
TypeError: list indices must be integers or slices, not tuple

>Solution :

Try this:

dflist = [df1, df2, df3]
new_dflist=[]
for n in dflist:
    new_dflist.append(pd.concat(df, n))

n is a dataframe and you are trying to put it in list index
