[Python] Python making API data calls of previous GitHub commits - this is not supposed to...

Is there any particular reason as to why my code, which is deigned to retrieve the latest commits from my GitHub repository, keeps sending me not only an email of the latest commits, but also an email of the previous commits (the commit before the latest commit) as well.

This is despite me telling it to only ping an email of the latest commits. I fail to see why this is so difficult for Python to work out and its making me infuriated.

This runs through a for loop which contains a set() of remote GitHub repos and fetches the data through their respective API calls. It is then supposed to populate the repo_data list by .append(ing)()` each repo's data.

It works perfectly, all returning 200 response codes & it prints the commit data for each repo (once & they're the latest commit SHA's as well), however, it's still also sending an email of the previous commit data. There is absolutely no reason for this this.

This is my MRE:

#commit_notify.py
import requests
import send_email

# GitHub repository info
OWNER = "<OWNER>"
GITHUB_TOKEN = "<GITHUB_TOKEN>"
GITHUB_API_URL = "https://api.github.com/repos/{owner}/{repo}/commits"

if not GITHUB_TOKEN:
raise ValueError("GITHUB_TOKEN is not set. Please set the environment variable.")

# Function to get the latest commit hash from GitHub
def get_latest_commit() -> str:

repo_data = []
headers = {"Authorization": f"token {GITHUB_TOKEN}"}
repos = {"<Remote Repo>", "<Remote Repo>", "<Remote Repo>", "<Remote Repo>"}

for repo in repos:

try:
url = GITHUB_API_URL.format(owner=OWNER, repo=repo)
response = requests.get(url,headers = headers)
print(response)
except requests.exceptions.RequestException as e:
print(f"Request failed for {repo}: {e}")

continue

if response.status_code == 200:
commits = response.json()
latest_commit_sha = commits[0]["sha"]
latest_commit_date = commits[0]["commit"]["author"]["date"]
latest_commit_id = commits[0]["author"]["id"]

repo_data.append({
"repo" : repo,
"sha" : latest_commit_sha,
"url" : url,
"date" : latest_commit_date,
"id" : latest_commit_id
})

continue

else:
print(f"Error fetching commits for {repo}: {response.status_code}")
print(f"Error details: {response.text}")

continue

if repo_data:
send_email.send_message(repo_data)

return repo_data

if __name__ == "__main__":
get_latest_commit()


Below is the send_email() module.

#send_email.py
import smtplib

from email.mime.multipart import MIMEMultipart

DOMAIN = "<DOMAIN>" #Sender Domain
GITHUB_URL = "https://github.com/{owner}"

#SMTP Server Information
SMTP_SERVER = "<SMTP_SERVER>"
SMTP_EMAIL = "<SMTP_EMAIL>"
SMTP_PASSWORD = "<SMTP_PASSWORD>"
SMTP_PORT = <PORT>

#Recipient Information
receiver_email = "<receiver_email>"

#Sender Information
sender_email = f"notifications{DOMAIN}"


def send_message(latest_commit_data:dict) -> None:

resource_data_table = ""
for data in latest_commit_data:
resource_data_table += f"""

msg = MIMEMultipart()

msg.attach(MIMEText(body, "html"))

try:
