python - 生成所有可能的字符串组合

Question

我正在尝试打印两个字符串的所有组合。

attributes = "old green".split()
persons = "car bike".split() 

我的期望:

old car
old bike
green car
green bike

到目前为止我尝试了什么:

from itertools import product

attributes = "old green".split()
persons = "car bike".split() 

print([list(zip(attributes, p)) for p in product(persons,repeat=1)]) 

Answer 1

您必须将persons 和 attributes 传递给product:

>>> [p for p in product(attributes, persons)]
[('old', 'car'), ('old', 'bike'), ('green', 'car'), ('green', 'bike')]

然后连接这些字符串:

>>> [' '.join(p) for p in product(attributes, persons)]
['old car', 'old bike', 'green car', 'green bike']

如果您想单独打印它们，您可以使用 for 循环代替列表理解:

for p in product(attributes, persons):
    print(' '.join(p))
