Printing 2 dimension list by row and column

Print the 2-dimensional list mult_table by row and column. Using nested loops. Sample output for the given program(without spacing between each row):

1 | 2 | 3

2 | 4 | 6

3 | 6 | 9

This is my code: I tried using a nested loop but I have my output at the bottom. It has the extra | at the end

  for row in mult_table:
    for cell in row:
       print(cell,end=' | ' )
  print()

1 | 2 | 3 |

2 | 4 | 6 |

3 | 6 | 9 |

user_input= input() #requets input from user
lines = user_input.split(',') # splits input into string list called lines

# This line uses a construct called a list comprehension, introduced elsewhere,
# to convert the input string into a two-dimensional list.
# Ex: 1 2, 2 4 is converted to [ [1, 2], [2, 4] ]

mult_table = [[int(num) for num in line.split()] for line in lines] #forms the nested list mult_table within the list lines

for row in mult_table: #iterates through each row of list, 0,1,2
    for n1 in row: #iterates through each value in the current row(ie. [0][0], [0][1], [0][2, and so forth
        if n1 == row[-1]: # will print only the value if its the last value in the list (prevents whitespace)
            print(n1)
        else: #prints the value of the current iteration within the nested list and the correct whitespace/designated seperator
            print(n1, end = ' | ')

I know my answer is a little long, but it works.

mult_table = [
    [1, 2, 3],
    [2, 4, 6],
    [3, 6, 9]
]

''' Your solution goes here '''
if len(mult_table) <= 3:
    mult_table[0].insert(1, ' | ')
    mult_table[0].insert(3, ' | ')
    
    mult_table[1].insert(1, ' | ')
    mult_table[1].insert(3, ' | ')

    mult_table[2].insert(1, ' | ')
    mult_table[2].insert(3, ' | ')
    
else:
    mult_table[0].insert(1, ' | ')
    mult_table[0].insert(3, ' | ')
    mult_table[0].insert(5, ' | ')
    
    mult_table[1].insert(1, ' | ')
    mult_table[1].insert(3, ' | ')
    mult_table[1].insert(5, ' | ')

    mult_table[2].insert(1, ' | ')
    mult_table[2].insert(3, ' | ')
    mult_table[2].insert(5, ' | ')
    
    mult_table[3].insert(1, ' | ')
    mult_table[3].insert(3, ' | ')
    mult_table[3].insert(5, ' | ')
    
for x in mult_table:
    for y in x:
        print(y, end='')
    print()

This is what I got:

user_input= input()
lines = user_input.`enter code here`split(',')

# This line uses a construct called a list comprehension, introduced elsewhere,
# to convert the input string into a two-dimensional list.
# Ex: 1 2, 2 4 is converted to [ [1, 2], [2, 4] ]

mult_table = [[int(num) for num in line.split()] for line in lines]

for row in mult_table:
    for cell in row:
        if cell == row[len(row) - 1]:
            print(cell, end='')
        else:
            print(cell, end=' | ')
    print()

Try this: 

    for x in mult_table:
        for x1 in x:
            if x1 == x[-1]:
                print (x1)
            else:
                print(x1 , end=' | ')

mult_table = [[int(num) for num in line.split()] for line in lines]

for row in mult_table:
   i=0
   for num in row:
     if i<len(row)-1:
        print(row[i],end=' | ')
        i=i+1
     else:
        print(row[i])

Try

for row in mult_table:
    print(" | ".join([str(cell) for cell in row]))

The join() joins the given elements into one string, using " | " as the separator. So for three in a row, it only uses two separators.
