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?
