Create list of dataframes

import pandas as pd array_len = 5

All elements of list reference the same df.

i.e. Assigning value to one df assigns to all df elements of array

df_array = [pd.DataFrame()]*array_len

Elements of list have unique df to assign values as needed

df_array = [] for i in range(array_len): df_array.append(pd.DataFrame())
Define list of unique dataframes
Effectively got only 1 dataframe defined
