how to extract data frame inside a pandas data frame column

Question

from a pandas data frame(3 * 5), how to extract a column (with rows containing data frame objects as values(each row data frame of 2 * 10) ) into a separate data frame(6 * 10 rows)

log_df['df_inside'] = log_df['input'].apply(lambda x :parser(x))

parser(x) returns a data frame(2 * 10) for each row after apply. After the above step, how to extract out df_inside data frame from the log entries?

Answer 1

pd.concat(log_df['df_inside'].tolist()).reset_index(drop=True) 工作
