combinations of all rows and cols from a dataframe

[marc nicole]

Hello everyone,

Given a dataframe like this:

2 6
8 5

I want to yield the following list of lists:
[  [[2],[6,5]],
[[2],[6]],
[[2],[5]],
[[8],[6,5]],
[[8],[6]],
[[8],[5]],
[[6],[2,8]],
[[6],[8]],
[[6],[2]],
[[5],[2,8]],
[[5],[2]],
[[5],[8]],
[[6,5],[2,8]]  ]

I have written the following (which doesn't yield the expected results)

import pandas as pd
> from itertools import combinations
> import numpy as np
> resList=[]
> resListTmp=[]
> resListTmp2=[]
> dataframe =
> pd.read_excel("C:\\Users\\user\\Desktop\\testData.xlsx",index_col=False,header=None)

for i in range(0, len(dataframe)+1):
>     for j in range(0, len(dataframe.columns)):
>         for k in range (0,len(dataframe)+1):
>             for xVals in list(combinations(dataframe.iloc[k:i,j], i)):
>                 if list(xVals) not in resListTmp:
>                     resListTmp.append(list(xVals))
>         resListTmp2.append(resListTmp)
>     resList.append(resListTmp2)
> print(resList)
>

What is wrong with my code?
