create a list with pairs from a column in pandas

Question

I have a column with pairs like these

id	pairs
1	a,b,c
2	b,d
3	a
4	d,e
5	g,h
6	a,h
7	f,d
8	o,p

I want to have these output

[('ca', 'b'), ('a', 'c'),('b','c'),('b','d'),('d','e'),('g','h'),('a','h'),('f','d'),('o','p')]

I did these, but not the desired solution

for pair in combinations([df['pairs']], 2):
print(pairs)

any suggestions?

Answer 1

try this

pairs = []

for row in df['pairs']:
    row_list = row.split(',')
    for pair in combinations(row_list, 2):
        pairs.append(pair)

print(pairs)
