我想将链表转换为单个数字
例如[1,2,0]应该转换为120
同时[-1,-2,0]应转换为-120
def list_to_number(head):
count=0
for i in head:
if (head[i]<0):
count+=1
elif(head[i]>0):
count=0
elif (head[i]==0):
continue
if (count==0):
n = list1(head)
return n
else:
n = [abs(k) for k in head]
n = list1(head)
return -n
pass
def list1(head):
n= map(str,head)
n = "".join(n)
n = int(n)
return n

你在这里尝试做什么有点模棱两可,尤其是负面的迹象。然而,一个良好的开端将是:
例如:
def join(X):
return int("".join(map(str,X)))
print join([1,2,0]) # 120
print join([0,2,1]) # 21
print join([9,4,2,4,230]) # 9424230

>>> def weird_conversion(digits):
... return sum(n * 10**i for (i, n) in enumerate(reversed(digits)))
...
>>> weird_conversion([1, 2, 0])
120
>>> weird_conversion([-1, -2, 0])
-120
>>> weird_conversion([-1, 2, 0])
-80
>>> weird_conversion([1, -2, 0])
80
