我有以下词典:dict = {('one','A'):8,('one','B'):19,('one','D'):29,('two','C'):18,('two','A'):10,('two','B'):4,('two','D'):2,('six','C'):4,('six','A'):4,('six','B'):4}
我将其转换为dataFrame,如下所示:
Score
one A 8
B 19
D 29
two C 18
A 10
B 4
D 2
six C 4
A 4
B 4
但是我想将字典转换为DF,其中来自元组的Key1是索引,而key2是列名:
A B C D
one 8 19 0 29
two 10 4 18 2
six 4 4 4 0
如何将字典转换为此类数据框?

unstack
的解决方案:
d = {('one','A'):8,('one','B'):19,('one','D'):29,('two','C'):18,
('two','A'):10,('two','B'):4,('two','D'):2,('six','C'):4,
('six','A'):4,('six','B'):4}
idx = pd.MultiIndex.from_tuples(d.keys())
print (pd.DataFrame(list(d.values()), index=idx, columns=['Score'])
.unstack(fill_value=0)['Score'])
A B C D
one 8 19 0 29
six 4 4 4 0
two 10 4 18 2

试试这个:
In [31]: pd.DataFrame({'Score':list(t.values())}, index=pd.MultiIndex.from_tuples(t.keys())).reset_index().pivot_table(index='level_0', columns='leve
...: l_1', fill_value=0).reset_index(level=0, drop=True)
Out[31]:
Score
level_1 A B C D
0 8 19 0 29
1 4 4 4 0
2 10 4 18 2
答案 2 :(得分:0)
你可以试试这个:,它的上一个版块的更新版本:
df = (pd.DataFrame({'Score':list(dict.values())},
index=pd.MultiIndex.from_tuples(dict.keys())).reset_index()
.pivot_table(index='level_0', columns='level_1', fill_value=0).reset_index())
df.columns = df.columns.droplevel(0)
df = df.rename(columns={'':'index'}).set_index('index')
