the function find_blank_square() is iterating over an int.
In line 422. Here's the code:
def find_blank_square(self, state):
"""Return the index of the blank square in a given state"""
for row in len(state):
for column in len(row):
if state[row][column] == 0:
index_blank_square = (row, column)
return index_blank_squarelen(state) and len(row) will always return an int.
I wonder how it passed the tests.
Edit: Found two more such cases!
