@HasanAhmadQ7 You can have attributes of type list. See for instance this code:

``` from netCDF4 import Dataset import numpy

f = Dataset("example.nc","w") x = f.createDimension("x",3) vlvar = f.createVariable("test_var", numpy.int32, ("x"))

here create an attribute as a list

vlvar.test_attr = ["string a", "string b"]

vlvar[:] = numpy.arange(3) f.close() ```

Having files with different values for the test_attr attribute will cause open_mfdataset to fail.

thanks for addressing this!
