Im having a bit of a problem with my project. My game is running fine but we're not allowed to have errors in our shell. I have created a game where balloons come flying at you and you have to pop them with an arrow controlled by the keyboard.
My tkinter is throwing out a TclError with Invalid Command Name when I use move and create.
Here is my coding:
#Add balloons to the canvas and make them fly
import random
balloon_id = list()
balloon_radius = list()
balloon_speed = list()
MIN_BALLOON_RADIUS = 10
MAX_BALLOON_RADIUS = 30
MAX_BALLOON_SPEED = 10
GAP = 100
def create_balloon():
x = WIDTH + GAP
y = random.randint(0, HEIGHT)
r = random.randint(MIN_BALLOON_RADIUS, MAX_BALLOON_RADIUS)
id1 = c.create_oval(x-r,y-r,x+r,y+r, outline='purple4', fill='MediumPurple2')
balloon_id.append(id1)
balloon_radius.append(r)
balloon_speed.append(random.randint(1, MAX_BALLOON_SPEED))
def move_balloons():
for i in range(len(balloon_id)):
c.move(balloon_id[i], -balloon_speed[i], 0)
It throws out these errors for create_balloon():
File "C:\Users\xxx\AppData\Local\Programs\Python\Python35-32\lib\tkinter\__init__.py", line 2334, in create_oval
return self._create('oval', args, kw)

*(args + self._options(cnf, kw))))
_tkinter.TclError: invalid command name ".55505712"
And this error for move_balloon():

move_balloons()
File "C:\Users\xxx\Documents\Varsity\xxx\Balloon Killer - 19342306.py", line 66, in move_balloons

I am getting an error when trying to run code and am unsure how to solve the issue. I am unsure what this datapath is and the error is coming straight from the matplotlib package. Any help is greatly appreciated. Here is the error I am getting:

I have made a small game where you progress through your life much like instlife but made in python with Tkinter. It is not complete and no where near being completed as i always get this same error.
This is my code
import tkinter
window = tkinter.Tk()
window.geometry("275x400")
window.title("Life")
year = 1980
age = 0
def ageButton():
global year
global age
year += 1
age += 1
yearText.configure(text=year)
dynamicText.configure("You are %d" %age)
yearText = tkinter.Label(window, text=year, anchor="n", width="270")
dynamicText = tkinter.Label(window, text="You are %d" %age, anchor="n",
width="270", height="495")
ageButton = tkinter.Button(window, text="Age", width="270",
command=ageButton)
ageButton.pack()
yearText.pack()
dynamicText.pack()
window.mainloop()
this is the error i get

When you call the configure method, you must tell tkinter what value you are changing. In your case you need to change this:
dynamicText.configure("You are %d" %age)
... to this:
dynamicText.configure(text="You are %d" %age)
I'm trying to import gif into a Tkinter.Label. I'm getting a file does not exist error. I have double checked the path and file name.
Below is the error message I get.

I'm a noob in python programming. Apologies if the questions is too trivial.
I get the same error and I'm sure the path is right as well. In fact, it seems to find the file every other time it tries, with very similar code.

for c in range(1,4):
fn = file_name(c)
try:

I cannot find a mistake in my code ;(
The error message might be backend and platform specific. As the error message seems to point to the blitting mechanism, you might want to try setting blit=False in FuncAnimation. Also, you might try some other backend to see if the problem persists. (Knowing your platform and matplotlib version might also help.)
Update: If setting blit=False, trying another backend, and updating matplotlib does not help, then a few suggestions:
Try to see manually if you code works with the initial data (init(); animate(0); fig.savefig("/tmp/test.png")) - if it throws an error, there is a static plotting problem to fix.
Now you initialize the plot twice (first in the code, then in init), you can take one away (e.g. do not define init_func)
Initializing the plots with [],[] leaves the scale uninitialized. You should probably use set_ylim, set_xlim with the plots and vmin, vmax keywords with the imshow images when you initialize them. (This could possibly have something to do with the exception you get!)
I'm trying to segment one window in curses into several sub-windows (with derwin()).
The code creates two sub-windows and I can add a string; no problem with the first function. The second one is pretty much exactly the same but gives me an error when I try to add a string with addstr()
class Window(GUI):
'''

self.Win_Count = 0
self.y_pos = y_pos

self.y_max = y_max
self.x_max = x_max
self.parent = screen
self.Target = Target
#Window-Objects
self.Win = self.create_win_parent(y_pos)
self.Name_Win = self.create_name_win(self.Win)
self.IP_Win = self.create_ip_win(self.Win)
def create_win_parent(self, y_pos):
y_size = 1
x_size = self.x_max - self.x_pos
new_win_obj = self.parent.derwin(y_size, x_size, self.y_pos, 0)
self.Win_Count += 1
return new_win_obj
def create_name_win(self, Win_Obj):
x = Win_Obj.derwin(1,40, 0,0)
x.box()
x.addstr(0,5," CUSTOMER NAME ")
return x
def create_ip_win(self, Win_Obj):
x = Win_Obj.derwin(1,15, 0,41)
x.box()
x.addstr(0,5," IP-ADDRESS ")
return x
I'm getting this vague error:

In this function Win_Obj.derwin(1,15, 0,41) shows that x-pos should between 0 and 14. While in the code addstr(0,5," IP-ADDRESS ") x starts at 5 and the length of string " IP-ADDRESS " is greater than (15-5). So you got the ERROR.
Not really sure about the specifics but it had ( as indicated by the interpreter, duh) something to do with the strings and them not having enough space in the subwindows i created.
