Solution() takes no arguments

The error "Solution() takes no arguments" typically occurs when you try to pass an argument to a class that does not accept any arguments in its constructor.

Here's an example code that could generate this error:

class Solution:
    def __init__(self):
        self.score = 0
    
    def update_score(self, new_score):
        self.score = new_score

solution = Solution(10) # this will raise "Solution() takes no arguments" error

In the above code, the `Solution` class does not accept any arguments in its constructor, yet we are trying to pass an argument of `10` when we create an instance of the class. To fix this error, we need to remove the argument:

class Solution:
    def __init__(self):
        self.score = 0
    
    def update_score(self, new_score):
        self.score = new_score

solution = Solution() # no error

Now, we can create an instance of the `Solution` class without any arguments.
