重新发布更多详情..
我遇到以下错误,下面的代码,下面是我正在尝试做的事情,下面的代码工作正常,如果只有一个值...如果值更多我得到错误“太多解压缩的值“,如何在不改变原始目标的情况下修改代码......
如果任何值是带有值的键,则对于每个值(这是键)递归检查其值,直到没有并删除重复的行...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

EXPECTED OUTPUT

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
if v in dic and dic[v] == [""]:
del dic[v]
for k1,v1 in dic.items():
if key in v1:
dic[k1].append(v)
break
else:
dic[key] = [v]
if __name__ == '__main__':
main()
输出: -
LINE

LINE

Traceback (most recent call last):
File "tesst.py", line 28, in <module>
main()
File "tesst.py", line 18, in main
key, v = spl
ValueError: too many values to unpack
答案 0 :(得分:0)
split
返回一个列表。因此,如果spl
中有两个以上的元素,您将获得ValueError
。
示例:
>>> a = [1,2]
>>> b,c = a
>>> b
1
>>> c
2
>>> a = [1,2,3]
>>> b,c = a
Traceback (most recent call last):
File "<pyshell#5>", line 1, in <module>
b,c = a
ValueError: too many values to unpack
所以你的代码应该是这样的:
key = spl[0]
v = set(spl[1:])
