我在下面的代码中遇到了以下错误,基本上下面是我想要做的,我怎样才能在不改变原始目标的情况下修改我的代码......
- 如果任何值是没有值的键,则从输入中删除该行
如果任何值是具有值的键,则对于每个值(即键)递归检查其值,直到没有值并删除重复行...示例输入和输出如下所示:
KEY VALUES 353311 344670 332807 353314 338169 334478 334478 123456 34567 123456 98670 34567 11111 353314 353311 348521 350166 350168 350169 350170 350166 348521 350168 348521 350169 348521 350170 348521 EXPECTED OUTPUT 344670 332807 353314 353311 338169 334478 123456 34567 98670 11111 348521 350166 350168 350169 350170
代码:-
from collections import OrderedDict def main (): with open('gerrit_dependencylist.txt') as f: dic = OrderedDict() seen = set() for line in f: #print dic,line spl = line.split() #print "SPL" #print spl if len(spl) == 1: key = spl[0] v = '' else: print "LINE" print line key, v = spl[0], spl[1:] for value in v: if value in dic and dic[value] == [""]: del dic[v] for k1,v1 in dic.iteritems(): if key in v1: dic[k1].append(v) break else: dic[key] = [v] if __name__ == '__main__': main()
输出:-
