python - Create a script to add delimited text layer in QGIS

I'm trying to use QgsVectorLayer() function to add delimited text layer in QGIS. So I have a txt file (T_1999_1_2.txt) in path: "D:\PATRICIA\DOCUMENTOS\ESTACOES METEOROLOGICAS\DADOS METEOROLOGICOS\T" and I want to create a shapefile named: T_1999_1_2.shp. The txt file structure is:

par;num;ano;mes;dia;D;btq 3;705;1999;1;2;-999,9;S;40,43885833;-8,43994167
3;619;1999;1;2;25,0;A;41,70972;-8,02699 3;718;1999;1;2;104,0;A;39,78055278;-8,82096667 3;766;1999;1;2;28,0;A;38,76620278;-9,12749444 3;560;1999;1;2;333,0;A;40,71492778;-7,89591667 3;669;1999;1;2;-999,9;S;39,83950000;-7,47866944 3;848;1999;1;2;-999,9;S;38,48486667;-7,47291667 3;555;1999;1;2;8,0;A;41,70655556;-8,80210833

I have tried to run the script but appears the same window error ("Error in file. File cannot be opened or delimiter parameters are not valid") My sript is the following one:

uri = "D:\PATRICIA\DOCUMENTOS\ESTACOES METEOROLOGICAS\DADOS METEOROLOGICOS\T\T_1999_1_2.txt?delimiter=%s&xField=%s&yField=%s" % (";", "x", "y") 

vlayer = QgsVectorLayer(uri, "D:\PATRICIA\IG\QGIS\FWI\T\T_1999_1_2.shp", "delimitedtext")

I don't understand, why it doesn't work.

Answer

Change variables indir and outdir according to your need. The code will find each file with extension 'txt' in indir and every subdirectory of indir. If you need another coordinate system than EPSG 4326, please change the EPSG number in line 9. The converted files will be written to directory outdir.

import os
indir = 'G:/LANUV'
outdir = 'G:/LANUV'
for root, dirs, files in os.walk(indir):
    for file in files:

        if file.endswith('.txt'):
            fullname = os.path.join(root, file).replace('\\', '/')
            filename = os.path.splitext(os.path.basename(fullname))[0]
            uri = 'file:///%s?crs=%s&delimiter=%s&xField=%s&yField=%s&decimal=%s' % (fullname, 'EPSG:4326', ';', 'x', 'y', ',')
            layer = QgsVectorLayer(uri, 'my_layer', 'delimitedtext')
            QgsVectorFileWriter.writeAsVectorFormat(layer, outdir + '/' + filename + '.shp', 'CP1250', None, 'ESRI Shapefile')

Copy the code and paste it into the Python console.
