Automatically install and uninstall app by powershell in Windows wrapper in Python code

#automation #installation #powershell #python

Dear folks, sometimes you might run into the task where you need to automatically install something in Windows.

Recently, I needed to do that task. So today I'm gonna share with you how to do that in powershell wrapper by Python.

I.What is powershell:

You might want to checkout in wiki

Powershell is a shell tool available in windows (since Windows 8)

It has more functionality compared to the good old command in DOS

II.Real world problem:

We would need to check if the app is installed yet, if it is installed and it is the latest version -> skip. If it is installed but the version is not latest --> uninstall then install.

If the app is not installed yet, --> proceed to install the latest version.

1.Get the current running version of the app:

The sample app we're working on would be "Cốc Cốc" browser.

 def get_current_login_user(): import subprocess import re p1 = subprocess.Popen(["powershell.exe", "whoami"], stdout=subprocess.PIPE, stderr=subprocess.PIPE) who_am_i = p1.communicate()[0] user_name = re.split(r'\\r', (re.split(r'.\\\\', str(who_am_i))[1]))[0] return user_name def get_coccoc_version_folder_name(): import subprocess import re p = subprocess.Popen(["powershell.exe", f"cd C:\\Users\\{current_user}\\AppData\\Local\\CocCoc\\Browser\\Application; ls"], stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True) current_dir = str(p.communicate()[0]) coccoc_version = re.findall(r'\b\d+\.+\b\d+\.\b\d+\.+\d*', current_dir)[0] return coccoc_version
Enter fullscreen mode Exit fullscreen mode

2.Get the latest version info stored in yaml file:

yaml_made_utils = YamlUtils() configuration_info = None configuration_path = '/resources/configurations.yaml' def get_configurations_info(): if configuration_info is None: return yaml_made_utils.read_data_from_file(os.getcwd() + configuration_path) else: return configuration_info class CocCocConfigs: COCCOC_DEV_VERSION = get_configurations_info()['coccoc_dev_version'] @staticmethod def update_coccoc_dev_version(coccoc_version): data = get_configurations_info() data['coccoc_dev_version'] = coccoc_version return yaml_made_utils.write_data_to_file(data, os.getcwd() + configuration_path)
Enter fullscreen mode Exit fullscreen mode

3.Uninstall the app

 def uninstall_coccoc_silently(): import subprocess p = subprocess.Popen(["powershell.exe", f"cd C:\\Users\\{current_user}\\AppData\\Local\\CocCoc\\Browser\\Application" f"\\{get_coccoc_version_folder_name()}" f"\\Installer; .\\setup.exe --uninstall --force-uninstall"], stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True) p.communicate()
Enter fullscreen mode Exit fullscreen mode

4.Install the app

 def install_coccoc_silently(): import subprocess p = subprocess.Popen(["powershell.exe", f"cd C:\\coccoc-dev; .\\{coccoc_installer_name} /silent /install"], stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True) p.communicate()
Enter fullscreen mode Exit fullscreen mode

5.Main function to run would be like :

 def main(): if check_if_coccoc_is_installed(): coccoc_version = get_coccoc_version_folder_name() from configs.yaml_configs import CocCocConfigs if coccoc_version in CocCocConfigs.COCCOC_DEV_VERSION: pass else: uninstall_coccoc_silently() import time time.sleep(5) install_coccoc_silently() else: install_coccoc_silently() if __name__ == "__main__": main()
Enter fullscreen mode Exit fullscreen mode
