Python字典小脚本

大概是这样的。两个字典。混合进去生成一个字典。列如字典1.txt的内容为xxx。字典2.txt的内容为123456 
要生成xxx123456或者123456xxx这样的字典

a =[]
for line in open('1.txt','r').readlines():
    line = line.strip()
    if len(line)>0: a.append(line)
b =[]
for line in open('2.txt','r').readlines():
    line = line.strip()
    if len(line)>0: b.append(line)
dy = {'0':a,'1':b}
wcd = 2
allpwd = []
def genfromstr(genedstr):
    if len(genedstr) == 1 : return  dy[genedstr[0]][:]
    pwds = []
    repwd = genfromstr(genedstr[1:])
    allpwd.extend(repwd)
    for pwd in repwd:
        for opwd in dy[genedstr[0]]:
            pwds.append(opwd+pwd)
    return pwds


for i in range(0,1<<wcd):
    genedstr = bin(i)[2:]
    genedstr = '0'*(wcd-len(genedstr)) + genedstr
    allpwd.extend(genfromstr(genedstr))

allpwd = list(set(allpwd))
print allpwd
output = open('3.txt', 'a+')
for p in allpwd:
    output.write(p+'\n')
output.close()
