Python學習筆記：實驗設計組合(二)

本文的起源來自於iThelp中網友的提問：

程式碼是我自已寫的。

import pandas as pd
import numpy as np

df = pd.DataFrame(
    {
      'GROUP':   ['R','W','W','R','R','W'],
      'GOAT':    ['15/10','10/7/11','9','12','8/13','10'],
      'TYPE':    ['A/B','A/B/B','A','B','B/A','B'],
      'TIME': [2,3,2,2,3,2]
    }
)

df

Out[1]:

In [2]:

df_temp = df.copy()
df_temp['GOAT_sub'] = df_temp['GOAT'].str.split('/').tolist()
df_temp['TYPE_sub'] = df_temp['TYPE'].str.split('/').tolist()
