Open a Pycharm Pyhton project fom another Pycharm Python project

I am not a programmer, so please bear with me if I'm inaccurate or don't really understand the replies.

I use pycharm, it works really well for me, python scripts are called projects in pycharm and I am running a couple of webscraping scripts to retrieve competitor prices on the internet. They are quite simple but work rather well. In order to go through the process I have to call every script (one for every competitor) independently, wait for it to finish, then I call the other one, etc. I could actually call or run all them simultaneously but it gets visually very messy, there are errors sometimes and it's just simpler to run one at a time, and get the results, they take 10-15 minutes each tops.

But I can't just sit around to wait for them to finish. I tried merging them into one large project but that was really messy, as every webpage has nuances, differences, I use different variables for every page to allow for differences, it's just simpler this way. But it is time consuming and basically forces me to stay put while running them.

I am trying to automate the process and am using tkinter to write a small project that would (ideally) call or run each one, one at a time, and I also hope to retrieve an exit code as well from every project that runs, in order for me to know if the project/script ran properly or not.

I have tkinter semi sorted out and have managed to get buttons, a clock, etc up and running (I am planning on running this script four times a day, every 3 hours approximately). I am confident I can do the GUI tkinter bit.

But I have been unable to call / run / import a pycharm project from another pycharm project. Here's the last iteration of what I have been trying out and using (these are called when pressing a button on the tkinter GUI:

  # create button, link it to run web price scraper program
    webscraperbutton = Button(self, text="Run", command=self.run_price_scraper)
    # place button at (400,100)
    webscraperbutton.place(x=200, y=100)

def run_price_scraper(self):
    # exec(open('/Users/manuel/PycharmProjects/PriceScraper/main.py').read())
    # os.system("/Users/manuel/PycharmProjects/PriceScraper/main.py")
    # subprocess.call('/Users/manuel/PycharmProjects/PriceScraper/main.py', shell=True)

They are all #d as I have been trying various combinations but nothing works so far.

Here are the errors I get:

subprocess.call('/Users/manuel/PycharmProjects/PriceScraper/main.py', shell=True)

How can I, in a simple way, just call or run another pycharm project, let it run through and get an exit code ?

I have thought of trying to make a Python app out of every project / script, and try calling an app instead, but I have no idea if that is even doable.

Any help is very welcome.

Thanks
