from itertools import product
a_list=["a1","a2","a3"]
b_list=["b1","b2","b3"]
c_list=["c1","c2","c3"]

for a in a_list:
    for b in b_list:
        for c in c_list:
            if "2" in a and "2" in b and "2" in c:
                print a,b,c

#用product实现,避免多重循环
for a,b,c in product(a_list,b_list,c_list):
    if "2" in a and "2" in b and "2" in c:
        print a, b, c
