How to add delimitedtext Layer via Python in QGIS 3?

Question

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

uri = ("file:///{}?"
 "&delimiter={}"
 "&xField={}"
 "&yField={}"
 "&crs={}"
 "&decimal").format(tab_text,
 "\t",
 "Rechtswert",
 "Hochwert",
 "EPSG:31468",",")
vlayer = QgsVectorLayer(uri, "layer", "delimitedtext")

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

Answer 1

Just add add another backslash when specifying tabs:

"\\t"

• RickJames: Thats not working because my delimiter is a tab. If I try double backslash i get "\t" as delimiter
• Joseph: @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.
• RickJames: you are right it worked. The other problem was my coordinate system.
• Joseph: @RickJames - Glad it worked :)
• user1655130: Why the need to use \\t as oppose to \t.
