Question

有2个列表（但可以有很多）：

a = ['Sasha ','walked along ','the highway']
b = ['Masha ','ran on ','the road']

我需要显示所有选项：

Sasha沿着高速公路走了
  萨莎沿着这条路走了
  玛莎沿着高速公路走
  玛莎沿着路走
  萨莎在高速公路上跑了
  萨莎在路上跑
  玛莎在高速公路上跑
  玛莎在路上跑

Answer 1

将itertools.product与str.join一起使用：

from itertools import product

a = ['Sasha ','walked along ','the highway']
b = ['Masha ','ran on ','the road']

# option 1: list comprehension
res = [''.join(tup) for tup in product(*zip(a, b))]

# option 2: map
res = list(map(''.join, product(*zip(a, b))))

['Sasha walked along the highway',
 'Sasha walked along the road',
 'Sasha ran on the highway',
 'Sasha ran on the road',
 'Masha walked along the highway',
 'Masha walked along the road',
 'Masha ran on the highway',
 'Masha ran on the road']

Answer 2

由于要打印所有选项，因此可以尝试以下操作：

a = ['Sasha ','walked along ','the highway']
b = ['Masha ','ran on ','the road']
ab = [list(i) for i in zip(a,b)]
for i in ab[0]:
    for j in ab[1]:
        for k in ab[2]:
            print(i,j,k)

输出：

Sasha  walked along  the highway
Sasha  walked along  the road
Sasha  ran on  the highway
Sasha  ran on  the road
Masha  walked along  the highway
Masha  walked along  the road
Masha  ran on  the highway
Masha  ran on  the road

Answer 3

简单地说，没有itertools和zip：

def scr(*lists):

    rslt=[""]
    for idx in range(len(lists[0])): # all of the lists has the same length

        r=[]
        for s in rslt:
            for l in lists:
                r.append( s+l[idx] )              
        rslt=r
    return rslt


print(scr(a,b))

Answer 4

重命名您的版本。这是正确的解决方案：

    a = ['Sasha ','Masha ']
    b = ['walked along ','ran on ']
    c = ['the highway','the road']

    ab = [list(i) for i in (a,b,c)]
    for x in ab[0]:
        for y in ab[1]:
            for z in ab[2]:
                print(x + y + z)

    Sasha walked along the highway
    Sasha walked along the road
    Sasha ran on the highway
    Sasha ran on the road
    Masha walked along the highway
    Masha walked along the road
    Masha ran on the highway
    Masha ran on the road
