How to use python to check for and install library's

Question

Is there a way to get this to work as every time I run it, It Won't give me a output, just "PRESS ANY KEY TO CONTINUE..."

as this is currently a test to read the modules I would like it to print the results as well

all help is appreciated

# Import the necessary packages
import pip

# Create a list of packages to install
packages_to_install = ["numpy", "pandas", "matplotlib"]

# List all of the installed packages
installed_packages = pip.freeze()

# Compare the list of installed packages to the list of packages to install
for package in packages_to_install:
    if package not in installed_packages:
        # Print the List of uninstalled packages
        print(package)

Answer 1

try this:

import importlib
import subprocess
import sys

packages_to_install = ["numpy", "pandas", "matplotlib"]

def check_and_install_packages(packages):
    for package in packages:
        try:
            importlib.import_module(package)
            print(f"{package} is already installed.")
        except ImportError:
            print(f"{package} is not installed. Installing...")
            subprocess.check_call([sys.executable, "-m", "pip", "install", package])
            print(f"{package} installed successfully.")

# Check and install packages if needed
check_and_install_packages(packages_to_install)

# Rest of your script can now safely use the installed packages
