我创建了一个包含三列所有唯一性的列表，应该是包含14个值的列表，但是，当我创建一个新的DataFrame时，它被视为三个值。
`names_cat=
((df_cat.sex.unique(),df_cat.generation.unique(),df_cat.age.unique()))
names_cat=list(np.array(names_cat))
names_cat`
`[[male, female]
Categories (2, object): [male, female],
[Generation X, Silent, G.I. Generation, Boomers, Millenials, Generation
Z]
Categories (6, object): [Generation X, Silent, G.I. Generation, Boomers,
Millenials, Generation Z],
[15-24 years, 35-54 years, 75+ years, 25-34 years, 55-74 years, 5-14
years]
Categories (6, object): [15-24 years, 35-54 years, 75+ years, 25-34
years, 55-74 years, 5-14 years]]`
`df_cat_processed=pd.DataFrame((df_cat_coded),columns=(names_cat))`
`ValueError: Shape of passed values is (14, 27820), indices imply (3,
27820)`
