Crash on launch: TypeError 'tuple' object does not support item assignment (Python 3.10+)

[Focing123]

Crash on Launch with Python 3.10+ (Tuple Immutability Error)

Description

When launching Mentalist v2.0.0 using modern Python versions (tested on Python 3.11 on Kali Linux), the application crashes immediately at startup with a TypeError.

The issue occurs because the code attempts to modify a tuple that stores the window size.

Error Traceback

TypeError: 'tuple' object does not support item assignment
File ".../mentalist/view/main.py", line 172, in __init__
    size[1] = h - 10

---

Cause

In mentalist/view/main.py:

size = tuple(int(_) for _ in self.master.geometry().split('+')[0].split('x'))

Later in the code:

if h < size[1]:
    size[1] = h - 10

size is defined as a tuple, which is immutable in Python. Attempting to assign a new value to size[1] results in a crash.

This behavior likely worked in older environments if a list was returned, but with modern Python/Tkinter behavior, the result is now consistently a tuple.

---

Proposed Fix

Convert size to a list before modifying it, and back to a tuple when passing it to geometry():

size = list(int(_) for _ in self.master.geometry().split('+')[0].split('x'))

And later:

self.master.geometry("%dx%d+%d+%d" % (tuple(size) + (x, y)))

Environment

• OS: Kali Linux (Debian-based)
• Python: 3.11
• Mentalist version: 2.0.0

---

This change resolves the crash and allows the GUI to launch normally.
