我有一个FileName = '../../Datasets/hc-1/d13921/d1392101.dat'
,每行有多个列,需要按列拆分为新行
DataFrame
当前(缩短版)看起来像这样
DataFrame
对于每个|---------------------------------------------------------------------------------------------------------------------------------|
|institution_short_name |interest_paid1 |interest_paid2 |product_detail_value_min |term_01m_value |term_02y_value |term_03m_value |
|---------------------------------------------------------------------------------------------------------------------------------|
|One |Z |Q |2000 |0.50 |0.75 |0.75 |
|One |Z |Q |5000 |0.50 |3.65 |3.75 |
|One |M |M |20000 |Nan |3.65 |Nan |
|---------------------------------------------------------------------------------------------------------------------------------|
列,例如,我想从列的名称中提取01m,02y,03m以及该列下该行的值,并将其爆炸如下:
term
我不是要求一个完整的解决方案,只是让我开始的事情。谢谢!
答案 0 :(得分:2)
您可以查看wide_to_long
pd.wide_to_long(df.repalce('Nan',np.nan),['term'],i=['institution_short_name','interest_paid1','interest_paid2','product_detail_value_min'],j='Term',suffix='\\w+').reset_index().dropna()
