python - 添加每個組上方的每個組的名稱

Question

我有一個excel文件，其中按行列出的樣本和列為列的屬性。 我正在使用python按一個或多個屬性對樣本進行分組，並使用xlsxwriter導出。 有沒有辦法在組上方的行中自動插入每個分組的標題？

type1 = ['a', 'c', 'e']
t1 = result.loc[df['Name'].isin(type1)]

type2 = ['b','f']
t2 = result.loc[df['Name'].isin(type2)]

group_by_type = [t1, t2]

編輯

Answer 1

您可以使用帶有keys參數的concat ：

np.random.seed(0)
df1 = pd.DataFrame(np.random.choice(10, (3, 3)), columns=list('ABC'))
df2 = pd.DataFrame(np.random.choice(10, (3, 3)), columns=list('DEF'))

titles = ['first', 'second']
pd.concat([df1, df2], keys=titles, axis=1)

  first       second      
      A  B  C      D  E  F
0     5  0  3      4  7  6
1     3  7  9      8  8  1
2     3  5  2      6  7  7
