split dataframe list into multiple rows

splitdataframlist.py

def splitDataFrameList(df,target_column):
    ''' df = dataframe to split,
    target_column = the column containing the values to split
    returns: a dataframe with each entry for the target column separated, with each element moved into a new row. 
    The values in the other columns are duplicated across the newly divided rows.
    '''
    def splitListToRows(row,row_accumulator,target_column):
        split_row = row[target_column]
        for s in split_row:
            new_row = row.to_dict()
            new_row[target_column] = s
            row_accumulator.append(new_row)
    new_rows = []
    df.apply(splitListToRows,axis=1,args = (new_rows,target_column))

    return new_df

If the column has zero length list, no new rows will be generated
