home_dir = os.path.expanduser("~")

# Set the installation path for PyCharm
install_path = os.path.join(home_dir, "PyCharm")

# If the installation path does not exist, create it
if not os.path.exists(install_path):
    os.makedirs(install_path)

# Set installation configuration
config = {
    "type": "Standard",
    "components": ["Python", "Web", "Database"]
}
