I have several .qgz project in different directories. I would like to get all the (displayed) layer names from each project. I tried several forms of code to get it from documentation, but it only returns an empty list in each file.

for settlement in os.listdir(source):
    settlement_path = os.path.join(source, str(settlement))
    settlement_name = str(settlement)

    for qgz in os.listdir(settlement_path):
        if str(qgz).endswith('.qgz'):
            project = QgsProject.instance()
            layers_names = []

            for layer in project.mapLayers().values():

    Have you made sure your path (qgz) is correct?

  • I printed out the files and also made a join for paths but the results are same. Commented Nov 22, 2021 at 11:41
  • did you try printing out project.mapLayers()?

  • Returns empty dictionaries in each case. My qgzs for sure aren't empty. Commented Nov 22, 2021 at 11:58

You miss os.path.join in the second loop.




project.read(os.path.join(settlement_path, str(qgz)))
  • Wow It works! Funny, I tried joining in the second loop as a separate variable and it did not work but in this way it works perfectly. Thank you! Commented Nov 22, 2021 at 12:32
