python import os


def is_qt5widgets_dll_found():

    dll_path = r"C:\Path\to\qt5widgets.dll"  # Replace with the actual path of the dll file
    if os.path.isfile(dll_path):

        print("qt5widgets.dll found!")

    else:

        print("qt5widgets.dll not found.")

# Call the function to check if the dll file is found is_qt5widgets_dll_found()

In the above code, you need to replace `C:\Path\to\qt5widgets.dll` with the actual file path of the `qt5widgets.dll` file on your Windows 10 system. The code uses the `os.path.isfile()` function to check if the file exists at the given path. It will print either “qt5widgets.dll found!” or “qt5widgets.dll not found.” based on the result.

Please note that this code only checks for the existence of the file and does not fix any issues related to the DLL or the Qt framework. If you’re facing specific issues related to the `qt5widgets.dll` file on Windows 10, it’s recommended to consult the official Qt documentation or seek assistance from the Qt community for a more comprehensive solution.
