Question

required_output = [‘happy dinner’,’happy lunch’,’sad dinner’, ‘sad lunch’]

我需要生成所有可能的句子。

{{1}}

但我总是没有2个名单。有时我有3,4,6,8等名单。我需要帮助在python中动态生成所有可能的句子。谢谢!!

Answer 1

您可以使用itertools.product：

import itertools
list_1 = ['happy','sad'] 
list_2 = ['dinner','lunch'] 
l = [list_1, list_2]
final_list = ["{} {}".format(*i) for i in itertools.product(*l, repeat = 2)]

输出：

['happy dinner', 'happy lunch', 'sad dinner', 'sad lunch']

Answer 2

在多个列表案例中你可以这样做

试试这个： -

import itertools
final_list = [list1,list2,list3,....]
print(list(itertools.product(*final_list))) #you will get all possible matches

Answer 3

我可以提出一个想法，假设我有4个列表，每个列表都包含单词。现在，而不是直接组合它。我们可以先找到列表的所有组合。 2个单词句子，3个单词和4个单词的组合。

所有索引组合的集合都在index_combin列表中。这对您的数据也很有用。

另外，我们将使用它来从4个列表中获得2,3和4组合。这存储在sets中。

以下是代码：

import itertools as it

list_1 = ['happy','sad'];
list_2 = ['dinner','lunch'];
list_3 = ['indoor', 'outdoor', 'restaurant'];
list_4 = ['alone', 'together'];
combined = [list_1, list_2, list_3, list_4];

index_combin = [];
words_combin = [];

for i in range(2,len(combined)+1):
    dummy = it.combinations(range(0, len(combined)),i);
    index_combin.append(list(dummy));

sets = [];
for i in index_combin:
    for j in i:
        sets.append([combined[k] for k in j]);

for i in sets:
    for j in list(it.product(*i)):
        print(j)

<强>输出：
