How can I get rid of AttributeError problem?

Question

When I upload the python file to codePost.io, I get an error that says "EOF Error when reading a line". I tried to use "try and except" method but in this case I get an AttributeError. What should I do? Here is my code:

try:
    rows = int(input("Enter a number of rows: "))
    columns = int(input("Enter a number of columns: "))

    def print_rect(row, col):
      for r in range(1, row + 1):
        for i in range(1, col + 1):
          if r == 1 or r == row or i == 1 or i == col:
            print("*", end="")
          else:
            print(" ", end="")

        print()

    print_rect(rows, columns)
except EOFError:
    pass

Answer 1

Try this please:

try:
  print("Enter a number of rows:")
  rows = int(input())
  print("Enter a number of columns:")
  columns = int(input())

  def print_rect(row, col):
    for r in range(1, row + 1):
      for i in range(1, col + 1):
        if r == 1 or r == row or i == 1 or i == col:
          print("*", end="")
        else:
          print(" ", end="")

      print()

  print_rect(rows, columns)
 except EOFError:
    pass
