symbol.contents.symbology = zint.BARCODE_QRCODE
symbol.contents.scale = 2.5
symbol.contents.option_1 = 4
symbol.contents.border_width = 4
input = zint.instr('https://github.com/jmptbl/python-zint')
if zint.ZBarcode_Encode_and_Print(symbol, input, 0, 0) != 0:
    print 'error: %s' % symbol.contents.errtxt
    sys.exit(1)
zint.ZBarcode_Delete(symbol)
