Tkinter & matplotlib

[PillyChepper]

Again:
The error is:

Error:
Exception in Tkinter callback
Traceback (most recent call last):
  File "/home/captainkirk/.pyenv/versions/3.7.4/lib/python3.7/tkinter/__init__.py", line 1705, in __call__

    nPoints = int(pocetbodu_entry.get())
NameError: name 'pocetbodu_entry' is not defined

Which very clearly states that 'pocetbodu_entry' is not defined

I suggest that you run step by step through a debugger and watch the program flow.

I am getting different error, I'm sorry if I am misunderstanding something, but as far as I can understand it, pocetbodu_entry is defined and works fine, its the line 68 which I can't figure out, without the for cycle on line 67, everything works fine and gets ploted.

Error:
C:/Users/Admin/Downloads/Škola/Python projects/Hangman/testtest.py:66: MatplotlibDeprecationWarning: Adding an axes using the same arguments as a previous axes currently reuses the earlier instance.  In a future version, a new instance will always be created and returned.  Meanwhile, this warning can be suppressed, and the future behavior ensured, by passing a unique label to each axes instance.
