_tkinter.TclError: expected integer but got "200.0"

I am trying to make text fade in and out but all it does is gives an error message about being out of range. I've been told to use colormode(255) but it just does not work. I am unsure of whether 255 is to high or something but please help.

Answer 1

I tested your code and it works fine in a Python 2.7.10 environment with Turtle 0.0.2.

I think your problem is that you're passing the argument x/5 in FADE_IN_OUT , and you must be using python 3. The error you're getting,

_tkinter.TclError: expected integer but got "200.0"

is complaining about receiving a float instead of an integer. Try using Python 3's integer division operator // instead of a single / .

For example, call FADE_IN_OUT like this:

 FADE_IN_OUT("47 Studios", "center", "Arial", x//5, "normal", 2.5, 2.5, 5)

Or, try running your code in Python 2.
