Final answer:
To print a two-dimensional list by rows and columns in Python, use nested loops to iterate through the list elements, formatting the output with a pipe symbol and handling new lines appropriately.
Step-by-step explanation:
To print a two-dimensional list (mult_table) by row and column in Python, we can use nested loops. Below is a sample Python code snippet that accomplishes this task:
# Assuming mult_table is the list given as an input, for example
# mult_table = [[1, 2, 3], [2, 4, 6], [3, 6, 9]]
# We transform the input string into a 2D list first
input_string = '1 2 3,2 4 6,3 6 9'
rows = input_string.split(',')
mult_table = [list(map(int, row.split())) for row in rows]
# Now we use nested loops to print the table
for row in mult_table:
for column in row:
print(column, end=' | ')
print('\b\b ')
This will correctly format the output as described, with numbers separated by a pipe symbol ('|') and each row on a new line. The end=' | ' argument in the print function is used to append the pipe symbol after each number instead of the default newline character. '\b\b ' is used to remove the extra pipe at the end of each line.
