Python: Wait for process to finish before proceeding in loop?

Question

I'm attempting to use PDFkit to create PDFs of a site and I'm having some trouble:

for u in urls:
    for c in u.children:
        pdfkit.from_url(c, "test.pdf", configuration=config)

Running pdfkit on a single URL works fine, but trying to use it in a for loop causes problems. I think it's because it takes a while for each PDF to be generated.

Is there a way I could wait while pdfkit is running, and only proceed with the next URL when it has finished with the previous?

You need async/wait function for python.

so, look at these
