I'm solving leetcode's two sums and I get error __init__() missing 2 positional arguments

Here is my code:

class Solution(object):
 def __init__(self, nums, target):
 self.nums = nums
 self.target = target
 def twoSum(self):
 for i in range(0, len(self.nums)):
 j = self.target-self.nums[i]
 for a in range(i+1,len(self.nums)):
 if self.nums[a]==j:
 return "(%d, %d)" % (self.nums[i], self.nums[a])

The Solution class is probably missing array and target upon instantiation.

You can make it like so:

class Solution(object):

 def __init__(self, nums, target):
 self.nums = nums
 self.target = target

 def twoSum(self):
 for i in range(0, len(self.nums)):
 j = self.target-self.nums[i]
 for a in range(i+1,len(self.nums)):
 if self.nums[a]==j:
 return "(%d, %d)" % (self.nums[i], self.nums[a])

 nums = [1,2,3,4,5,6] # Array of numbers
 target = 7 # Target
 s = Solution(nums, target)
 print(s.twoSum())

EDIT:

I runned code in idle. This is what I get for your code:

But I found solution online, and it goes like this:

class Solution:
 # @return a tuple, (index1, index2)
 def twoSum(self, num, target):
 length = len(num)
 # use dict: value: index + 1
 # since there is only one solution, the right value must not be duplicated
 dic = 
 for i in range(0, length):
 val = num[i]
 if (target - val) in dic:
 return (dic[target - val], i + 1)
 dic[val] = i + 1



# test code
num=[2, 7, 11, 15]
t= 26
s = Solution()
print(s.twoSum(num, t))

The solution works in LeetCode interface.
