How do you multiply two numbers in a list?

Algorithm

Initialise the two linked lists.
Initialise two variables with 0 to store the two numbers.
Iterate over the two linked lists. Add each digit to the respective number variable at the end.
Multiply the resultant numbers and store the result in a variable.
Create a new list with the result.
Print the new list.

number = int(input (“Enter the number of which the user wants to print the multiplication table: “))
count = 1.
# we are using while loop for iterating the multiplication 10 times.
print (“The Multiplication Table of: “, number)
while count <= 10:
number = number * 1.
print (number, ‘x’, i, ‘=’, number * count)

How do you find the multiples of 10 in Python?

Basically, x%y returns the value of the remainder of x/y , so if the remainder is 0 , than x is evenly divisible by y . Therefore, if x%10 returns something other than a zero, x is not divisible by 10.
