# Create an empty list to store the matrix
matrix = []

# Iterate over each string in the list of lines
for line in lines:
    # Remove the newline character at the end
    line = line.strip()
    # Split the line into individual elements using comma as the separator
    elements = line.split(",")
    # Convert the elements to the appropriate data types as needed
    # Add the list of elements as a row in the matrix
    matrix.append([int(e) for e in elements])

# Print the matrix
