合併CSV中兩個不同列的所有值

Question

好的，所以我導入了一個CSV，然後我想將row[0]中的所有迭代值與row[1]中的迭代值合併。

csvfile = csv.reader(open(filename, 'rb'), delimiter=',') 

for row in csvfile: 
    row[0] + row[1] 

這樣，除了我希望所有的row[0]值的與所有的row[1]值的結合，即使他們不在同一行。

所以可以說我有兩列，一列是：

asparagus 
beets 
corn 
cucumbers 
tomatoes 

，另一個是：

pineapple 
orange 
apple 
raspberry 
blueberry 

我想有蘆筍所有列表2的組合，即：

asparagus pineapple 
asparagus orange 
asparagus apple 
asparagus raspberry 
asparagus blueberry 

然後去甜菜菠蘿等

Answer 1

In [1]: import csv 

In [2]: from itertools import product 

In [3]: csvfile = csv.reader(open('filename', 'rb'), delimiter=',') 

In [4]: list(product(*zip(*list(csvfile)))) 
Out[4]: 
[('asparagus', 'pineapple'), 
('asparagus', 'orange'), 
('asparagus', 'apple'), 
('asparagus', 'raspberry'), 
('asparagus', 'blueberry'), 
('beets', 'pineapple'), 
('beets', 'orange'), 
('beets', 'apple'), 
('beets', 'raspberry'), 
('beets', 'blueberry'), 
('corn', 'pineapple'), 
('corn', 'orange'), 
('corn', 'apple'), 
('corn', 'raspberry'), 
('corn', 'blueberry'), 
('cucumbers', 'pineapple'), 
('cucumbers', 'orange'), 
('cucumbers', 'apple'), 
('cucumbers', 'raspberry'), 
('cucumbers', 'blueberry'), 
('tomatoes', 'pineapple'), 
('tomatoes', 'orange'), 
('tomatoes', 'apple'), 
('tomatoes', 'raspberry'), 
('tomatoes', 'blueberry')] 

Answer 2

csvfile = csv.reader(open(filename, 'rb'), delimiter=',') 

combinations = [] 

for rowa in csvfile: 
    for rowb in csvfile: 
     combinations.append(rowa[0] + ' ' + rowb[1])
