I have a problem to add a *.tab file as delimitedtext layer in QGIS 3.

uri = ("file:///{}?"
vlayer = QgsVectorLayer(uri, "layer", "delimitedtext")

If I test the layer with .isValid I get a False. Did I have to name more variables?

Just add add another backslash when specifying tabs:

  • Thats not working because my delimiter is a tab. If I try double backslash i get "\t" as delimiter

  • @RickJames - Yes, a single slash is shown for me in the layer's information but to import it, I had to use double slashes. Tested on QGIS 3.0.1 for Win 7 64-bit.

    you are right it worked. The other problem was my coordinate system.

  • Why the need to use \\t as oppose to \t. Commented Dec 7, 2022 at 10:54
