如何在Python中尝试数据帧的所有可能组合，但又要管理行项的顺序？

import itertools
import pandas as pd

columns = ['A', 'B', 'C']
data = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]

combinations = []
for r in range(1, len(columns) + 1):
    combinations.extend(itertools.combinations(columns, r))

df = pd.DataFrame()

for combination in combinations:
    df['-'.join(combination)] = pd.Series([tuple(row[i] for i in range(len(columns)) if columns[i] in combination) for row in data])

df = df[columns]

import itertools
import pandas as pd

columns = ['A', 'B', 'C']
data = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]

combinations = []
for r in range(1, len(columns) + 1):
    combinations.extend(itertools.combinations(columns, r))

df = pd.DataFrame()

for combination in combinations:
    df['-'.join(combination)] = pd.Series([tuple(row[i] for i in range(len(columns)) if columns[i] in combination) for row in data])

df = df[columns]
