Python拆分list数据表

将某一列数据进行拆分

new_id, new_code = list(), list()
for i in range(df.shape[0]):
    a_id = df['loan_id'][i]
    r_code = df['irr24_reason_codes'][i]
    code_list = r_code.split(',')
    for j in range(len(code_list)):
        new_id.append(a_id)
        new_code.append(code_list[j])
data_irr24_reason_code = pd.DataFrame({'loan_id': new_id, 'irr24_reason_code': new_code})
