从两个列表创建组合并在 Python 中使用单独的键创建字典

Question

我有两个列表 t1 = ['C1'，'C2'，'C3'] t2 = ['提升'，'下降'，'恒定']

使用两个列表，我希望输出如下。有所有可能的组合

{
  'regime_1' : {
    'c1' : 'rising',
    'c2' : 'falling',
    'c3' : 'constant'
  },
    'regime_2' : {
    'c1' : 'rising',
    'c2' : 'falling',
    'c3' : 'falling'
  }
}

t1 列表中的元素不应在“regime”键中重复。我在python中编写了以下代码。

import itertools
t1 = ['C1', 'C2', 'C3']
t2 = ['raising', 'faling', 'constant']
combos = [str(i) +":"+ str(n) for i in t1 for n in t2]
combinations = dict(("regime_"+str(i+1),c) for i,c in enumerate(combos))

但我得到的输出是

{'regime_1': 'C1:raising', 'regime_2': 'C1:faling', 'regime_3': 'C1:constant', 'regime_4': 'C2:raising', 'regime_5': 'C2:faling', 'regime_6': 'C2:constant', 'regime_7': 'C3:raising', 'regime_8': 'C3:faling', 'regime_9': 'C3:constant'}

谢谢

Answer 1

我想这就是你所追求的：

from itertools import product

variables = ['C1', 'C2', 'C3']
values = ['rising', 'falling', 'constant']

d = {f'regime_{k+1}': dict(v)
     for k, v in enumerate(
        zip(variables, v) for v in product(values, repeat=len(variables))
    )}
print(d)

一些解释：

• product(values, repeat=len(variables)) 为您提供values 的笛卡尔积，重复数等于变量数。
• zip() 将变量与其生成的值配对。
• 通过枚举它们，您可以获得该制度的编号以及该制度的dict 的一组变量及其值。
• f 字符串从枚举 (+1) 中获取数字并创建一个键，从 zip 对象创建一个字典。

结果：

{
'regime_1': {'C1': 'rising', 'C2': 'rising', 'C3': 'rising'},
'regime_2': {'C1': 'rising', 'C2': 'rising', 'C3': 'falling'},
'regime_3': {'C1': 'rising', 'C2': 'rising', 'C3': 'constant'},
'regime_4': {'C1': 'rising', 'C2': 'falling', 'C3': 'rising'},
'regime_5': {'C1': 'rising', 'C2': 'falling', 'C3': 'falling'},
'regime_6': {'C1': 'rising', 'C2': 'falling', 'C3': 'constant'},
'regime_7': {'C1': 'rising', 'C2': 'constant', 'C3': 'rising'},
'regime_8': {'C1': 'rising', 'C2': 'constant', 'C3': 'falling'},
'regime_9': {'C1': 'rising', 'C2': 'constant', 'C3': 'constant'},
'regime_10': {'C1': 'falling', 'C2': 'rising', 'C3': 'rising'},
'regime_11': {'C1': 'falling', 'C2': 'rising', 'C3': 'falling'},
'regime_12': {'C1': 'falling', 'C2': 'rising', 'C3': 'constant'},
'regime_13': {'C1': 'falling', 'C2': 'falling', 'C3': 'rising'},
'regime_14': {'C1': 'falling', 'C2': 'falling', 'C3': 'falling'},
'regime_15': {'C1': 'falling', 'C2': 'falling', 'C3': 'constant'},
'regime_16': {'C1': 'falling', 'C2': 'constant', 'C3': 'rising'},
'regime_17': {'C1': 'falling', 'C2': 'constant', 'C3': 'falling'},
'regime_18': {'C1': 'falling', 'C2': 'constant', 'C3': 'constant'},
'regime_19': {'C1': 'constant', 'C2': 'rising', 'C3': 'rising'},
'regime_20': {'C1': 'constant', 'C2': 'rising', 'C3': 'falling'},
'regime_21': {'C1': 'constant', 'C2': 'rising', 'C3': 'constant'},
'regime_22': {'C1': 'constant', 'C2': 'falling', 'C3': 'rising'},
'regime_23': {'C1': 'constant', 'C2': 'falling', 'C3': 'falling'},
'regime_24': {'C1': 'constant', 'C2': 'falling', 'C3': 'constant'},
'regime_25': {'C1': 'constant', 'C2': 'constant', 'C3': 'rising'},
'regime_26': {'C1': 'constant', 'C2': 'constant', 'C3': 'falling'},
'regime_27': {'C1': 'constant', 'C2': 'constant', 'C3': 'constant'}
}

Answer 2

import re
import itertools

t1 = ['C1', 'C2', 'C3']
t2 = ['raising', 'faling', 'constant']

variant=0
return_dict=dict()

for current_tag1 in itertools.product(t2, repeat=len(t2)):
    return_dict['regime_%d' % variant]=dict(zip(t1,current_tag1))
    variant+=1

print return_dict

输出
