Hello, there is something wrong with instruction 1. It says to define dfs with the parameters of (graph, current_vertex, target_value, visited=None) Which i did exactly as it should be but would not let me pass the instruction, attached is a screenshot of what i had before i pressed ‘solution’. It makes me sad that this happens sometimes because it’s encouraging to get the green check of awesomeness.
here is the solutions definition of the function (for comparison)

# Build your depth-first search function below:
def dfs(graph, current_vertex, target_value, visited=None):
  if visited == None:
    visited = []
  visited.append(current_vertex)
  return visited

print(dfs(None, "bees?", None))
