我从您的问题中了解到的是,当您在两个文件中找到它们时,您想要对它们的数字进行求和,否则只需打印它们的原始值即可。您可以执行以下操作:lines1 = [i.split() for i in open('tmp.txt').readlines()]values,keys = zip(*lines1)dict1 = dict( zip(keys,values) )lines2 = [i.split() for i in open('tmp2.txt').readlines()]values,keys = zip(*lines2)dict2 = dict( zip(keys,values) )dict3 = {}for k1,v1 in dict1.items(): v2 = dict2.get(k1) if v2: dict3[k1] = str(float(v1)/float(v2)) else: dict3[k1] = v1for k2,v2 in dict2.items(): if not dict3.get(k2): dict3[k2] = v2out = open('output.txt','w')out.writelines(['%s\t%s\n' %\ (k[0],dict3[k[0]]) for k in sorted(dict3.items(), key=lambda x:x[1])])out.close()
