Python CSV转换所有行和列的组合

我有一个csv文件的名称和这些名称的变化。该文件如下所示：

Abigail | Abby | Abbey | Abbie
Abraham | Abe  |       |
Aidan   | Aodh | Aiden |

等等

我想知道是否有一个python脚本可供我使用，它可以为我这样配对：

Abigail Abby
Abigail Abbey,
Abigail Abbie,
Abby Abbey,
Abby Abbie,
Abbey Abbie,
Abraham Abe,
Aidan Aodh,
Aidan Aiden,
Aodh Aiden

即每行获得所有可能的组合。有人对此有什么建议吗？

您可以使用列表理解：

import csv
def row_combo(d):
   return [[a, k] for i, a in enumerate(d) for k in d[:i]+d[i+1:]]

r = [k for i in csv.reader(open('file.csv'), delimiter='|') for k in row_combo(i)]
final_r = [[a, b] for j, k in r if (a:=j.strip()) and (b:=k.strip())] #clean data

输出：

[['Abigail', 'Abby'], ['Abigail', 'Abbey'], ['Abigail', 'Abbie'], ['Abby', 'Abigail'], ['Abby', 'Abbey'], ['Abby', 'Abbie'], ['Abbey', 'Abigail'], ['Abbey', 'Abby'], ['Abbey', 'Abbie'], ['Abbie', 'Abigail'], ['Abbie', 'Abby'], ['Abbie', 'Abbey'], ['Abraham', 'Abe'], ['Abe', 'Abraham'], ['Aidan', 'Aodh'], ['Aidan', 'Aiden'], ['Aodh', 'Aidan'], ['Aodh', 'Aiden'], ['Aiden', 'Aidan'], ['Aiden', 'Aodh']]

首先，您必须将csv文件转换为以下列表：

import csv

with open('csv.csv') as file:
    names = [list(filter(None, row)) for row in csv.reader(file)]

你得到的是：

names = [["Abigail","Abby","Abbey","Abbie"],["Abraham","Abe"],["Aidan","Aodh","Aiden"]]

然后你可以很简单地这样做：

combinations = []

for row in names:
    for i,n1 in enumerate(row):
        for n2 in row[i+1:]:
            combinations.append((n1,n2))

结果:

[('Abigail', 'Abby'), ('Abigail', 'Abbey'), ('Abigail', 'Abbie'), ('Abby', 'Abbey'), ('Abby', 'Abbie'), ('Abbey', 'Abbie'), ('Abraham', 'Abe'), ('Aidan', 'Aodh'), ('Aidan', 'Aiden'), ('Aodh', 'Aiden')]

太好了，谢谢。要删除重复项，我刚刚做了

mylist=[k代表k，v代表groupby（排序（最终））]

谢谢，我刚刚提交了一个编辑来添加

row=list（filter（None，row））

以删除空字符串
