Problem with the for loop in a calculation and filtering the results of the loop with a condition >=

I need help with a "for" loop for a little video game i'm making. The problem is the for of for row loop in Rows_NextFights[0:] and its contents.

Premise that the arithmetic average (or mean) is already calculated correctly for a single monster, my idea is:

• Calculate the average Attacks for each monster (only Monster_home) from the NextFights database, based on the previous fights from the ResultsFights database. I currently calculate it for each individual monster, but I would like to calculate it for all monsters;

• Check and compare that each Monster_home of the NextFights database has the average => 1.10 (so a condition with "if");

• If a monster (Monster_home) does not have the mean >= 1.10 (so it has the mean < 1.10), then it won't be printed;

• if a monster (Monster_home) has the mean >= 1.10, then the names of the monsters that satisfy the condition will be printed. Precisely I don't want to print only the name of the monster, but I would like to print the next fight (located inside the NextFights database) related to the specific Monster_home, written like this Monster_home-Monster_away (with the dash), Island;

OUTPUT I WOULD LIKE TO RECEIVE: For example, considering Godzilla, Jafar, Merlock and Crono (which are the Monster_Homes in the NextFights database) and pretending they have respectively the averages Godzilla 1.20, Jafar 0.90, Merlock 1.34, Crono 1 and I set if Mean_Attacks_Only_Monster_home >= 1.10, then I would like to print this:

Godzilla-Kong, Sun Island
Merlock-Zurg, Moon Island

ERROR: I receive no errors, the printing is correct, but badly: I receive the printing of many meaningless lists/tuples. Considering that the (wrong) output result I receive is very long, I saved the screenshot in this image uploaded to an upload image HERE

P.S: if anyone would like to suggest calculating the mean using AVG() in SQL, but i want to continue using the python code (sum and the rest, as i'm already doing)

import sqlite3

conn = sqlite3.connect('/mydatabase.db')
cursor = conn.cursor()

#Example: Godzilla-Kong, Sun Island, etc...      
All_NextFights = cursor.execute('SELECT Monster_home||"-"||Monster_away, Tourney FROM NextFights')
Rows_NextFights = [cursor.fetchall()]

Only_Monster_home = cursor.execute('SELECT Attacks, Defence FROM ResultsFights')
Rows_Only_Monster_home = cursor.fetchall()

#Mean calculation of the points of the fights
Mean_Attacks_Only_Monster_home = sum(int(row[0]) for row in Rows_Only_Monster_home) / len(Rows_Only_Monster_home)

mylist = []

for row in Rows_NextFights[0:]:
    Fights_Range = row[0]  

    if Mean_Attacks_Only_Monster_home >= 1.10:
        mylist.append(row)
        #text.insert(tk.END, (str(mylist) + '\n'))
print((str(mylist) + '\n'))

This is my database for a test:

NextFights

CREATE TABLE "NextFights" (
    "id"    INTEGER,
    "Monster_home"  INTEGER,
    "Monster_away"  INTEGER,
    "Tourney"   INTEGER,
    PRIMARY KEY("id" AUTOINCREMENT)
);

1   Godzilla    Kong    Island Sun
2   Jafar   Zod Atene
3   Talos   Spectrus    Japan
4   Merlock Zurg     Moon Island
5   Crono   Iperione    Kripton

ResultsFights

CREATE TABLE "ResultsFights" (
    "id"    INTEGER,
    "Monster_home"  INTEGER,
    "Monster_away"  INTEGER,
    "Attacks"   INTEGER,
    "Defence"   INTEGER,
    PRIMARY KEY("id" AUTOINCREMENT)
);

1   Godzilla    Jafar   2   1
2   Talos   Godzilla    3   1
3   Spectrus    Godzilla    1   2
4   Godzilla    Talos   0   0
5   Godzilla    Zod 2   3       
6   Talos   Jafar   2   1
7   Talos   BigDanger   3   1
8   Bruto   Talos   1   2
9   Zod Talos   0   0
10  Talos   Spectrus    2   3

Can you help me please? Can you show me the solution code please? Thanks in advance, to anyone who will be kind enough to help me!!!
