"Implementing User Input and comments in a Script" Unable to run test cases

For this question:
Write a script that takes a number from a user’s input and prints out its multiplication table from 1 to 10.

The steps are as follows:

  1. Open the file named main.py in your editor.
  2. On the first line, add a docstring explaining what your file does. Then, assign a variable called number to the user’s input and cast it to an integer.
  3. Next, print 20 underscores as the top border of the table.
  4. Multiply your number with each number from 1 to 10 and print that out.
  5. Finally, print 20 underscores again for the bottom border of the table, as in step 3.
  6. Run the file by using the python main.py command.

I think I’ve written all correctly but Test cases 3 and 4 aren’t running.
I am not able to get what is the problem?
