Question

Hi! Can you help me to fix these error messages I get? Here is also some previous codes for my sudoku assignments if they help.

def row_correct(sudoku: list, row_no: int):

# Get the row to check

row = sudoku[row_no]

# Create a set to store the numbers that appear in the row

nums_in_row = set()

# Iterate through the elements in the row

for num in row:

# If the number is not 0 and it has already appeared in the set, return False

if num != 0 and num in nums_in_row:

return False

# If the number is not 0, add it to the set

elif num != 0:

nums_in_row.add(num)

# Return True if all checks pass

return True

def column_correct(sudoku, column_no):

column = []

# Extract the values in the specified column

for row in sudoku:

column.append(row[column_no])

# Check if the column contains each number from 1 to 9 at most once

for i in range(1, 10):

if column.count(i) > 1:

return False

return True
