Don't understand this TypeError: an integer is required

Question

Receiving a TypeError when trying to run:

File "/home/XX/PycharmProjects/rogue_like/venv/lib64/python3.7/site-packages/tcod/libtcodpy.py", line 1236, in console_put_char
    lib.TCOD_console_put_char(_console(con), x, y, _int(c), flag)
TypeError: an integer is required

Class Object:

    def __init__(self, x, y, char, color):
        self.x = x
        self.y = y
        self.char = char
        self.color = color

    def draw(self):
        libtcod.console_set_default_foreground(con, self.color)
        libtcod.console_put_char(con, self.x, self.y, self.char, libtcod.BKGND_NONE)

# later...

SCREEN_WIDTH = 80
SCREEN_HEIGHT = 50
player = Object(SCREEN_WIDTH/2, SCREEN_HEIGHT/2, '@', libtcod.yellow)

Following a roguelike tutorial and ran into this. Have tried passing an integer by changing the '@' to a number and other things. Have tried handing it to int(self.char) and other options but seem to be hitting a wall.

Any help would be great! Tried to include pertinent code, let me know if there's anything else.

EDIT:

"""
...
   Args:
    con (Console): Any Console instance.
    x (int): Character x position from the left.
    y (int): Character y position from the top.
    c (Union[int, AnyStr]): Character to draw, can be an integer or string.
    flag (int): Blending mode to use, defaults to BKGND_DEFAULT.
"""
lib.TCOD_console_put_char(_console(con), x, y, _int(c), flag)

Is it possible that `x` and `y` aren't integers? Does doing `int(self.x)` and `int(self.y)` in the function call help? — Green Cloak Guy, Sep 06 '19 at 23:44
I attempted your suggestion which I hadn't thought of it being another arg being the issue but it still did not work. SCREEN_WIDTH = 80 SCREEN_HEIGHT = 50 are whats being passed so they should both be integers. — Brendon O'Sullivan, Sep 06 '19 at 23:51
Can you post the lines 1230-1236 of the `libtcodpy.py` file? We might be able to tell which parameter is the problem. — Barmar, Sep 06 '19 at 23:57
check all arguments which should be integer in this line - `x, y, c, flag` — furas, Sep 07 '19 at 00:02
Check out http://sscce.org/ and try editing your question is it is complete and minimal. — Jean-Paul Calderone, Sep 07 '19 at 00:05

In Python 3, dividing two ints always produces a float, so 80/2 and 50/2 are producing floats, not ints. To make them ints, you could either use floor division (80//2) or cast to int (int(80/2)).

I guess your tutorial is for Python 2, cause in Python 2, dividing two ints always produces an int.
