df = pd.DataFrame(data_dict)
print(f"DataFrame:n{df}n")
print(f"column types:n{df.dtypes}")
col_one_list = df['one'].tolist()
col_one_arr = df['one'].to_numpy()
print(f"ncol_one_list:n{col_one_list}ntype:{type(col_one_list)}")
print(f"ncol_one_arr:n{col_one_arr}ntype:{type(col_one_arr)}")dataframe column in list
