Python 3.13.0 : simple script for update all python packages.

Simple script for update all python packages:

import subprocess
import sys
import datetime

log_file = "upgrade_log.txt"

def log(msg):
    with open(log_file, "a", encoding="utf-8") as f:
        f.write(msg + "\n")
    print(msg)

def get_installed_packages():
    result = subprocess.run(
        [sys.executable, "-m", "pip", "list", "--format=freeze"],
        capture_output=True,
        text=True
    )
    lines = result.stdout.strip().split("\n")
    packages = []
    for line in lines:
        if "@" in line:  # skip direct URL installs
            pkg = line.split("@")[0]
        else:
            pkg = line.split("==")[0]
        packages.append(pkg)
    return sorted(packages)

def upgrade_package(package):
    log(f"\n=== Updating: {package} ===")
    try:
        subprocess.check_call([sys.executable, "-m", "pip", "install", "--upgrade", package])
        log(f"[OK] Updated: {package}")
    except subprocess.CalledProcessError:
        log(f"[FAILED] Could not update: {package}")

def main():
    log(f"\n--- Upgrade started at {datetime.datetime.now()} ---\n")

    packages = get_installed_packages()
    log(f"Found {len(packages)} packages.\n")

    for pkg in packages:
        upgrade_package(pkg)

    log(f"\n--- Upgrade finished at {datetime.datetime.now()} ---\n")
