我有一个1-6的数字列表,需要所有可能的排列,并且需要存储在数据框中。但是我还需要数据框具有名为“第1个月”,“第2个月”,“第3个月”等的列。
所以我想要这样的东西:
Month 1 Month 2 Month 3 Month 4 Month 5 Month 6
1 2 3 4 5 6
1 2 3 4 6 5
1 2 3 5 4 6
1 2 3 5 6 4
etc.
我需要存储所有720个可能的排列。
我该怎么做?我尝试使用itertools.permutation
,但遇到了麻烦。

使用itertools.permutations
可以做到这一点:
import pandas as pd
import itertools
a = itertools.permutations([1,2,3,4,5,6])
df = pd.DataFrame(list(a), columns=['Month' + str(i) for i in range(1,7)])
将产生产量:
Month1 Month2 Month3 Month4 Month5 Month6
0 1 2 3 4 5 6
1 1 2 3 4 6 5
2 1 2 3 5 4 6
3 1 2 3 5 6 4

我不确定从排列中获取数据框会遇到什么麻烦。这是我的例子。
