Close a file created using GDAL

Question

I have problems to close a file created in GDAL

I have the following code (it's a part of bigger piece of code):

driver = gdal.GetDriverByName("GTiff")
SAL01=driver. Create(Fnout1,afile.shape[1],afile.shape[0],1,tipoarr)
SAL01.SetProjection(proj)
SAL01.SetGeoTransform(trans)
SAL01.GetRasterBand(1).SetNoDataValue(10000)
band = SAL01.GetRasterBand(1)
band.WriteArray(afile)
band.FlushCache()
band.ComputeStatistics(False)
Fnout.close()

The error when process Fnout.close() is 'str' object has no attribute 'close'

In fact, Fnout is a string (used to generate the file name) and not a 'file' object.

Any simple way to close the file using the string as reference?

Answer 1

For gdal >= 3.8:

Use Close not close (case sensitive). Or use a with statement as 3.8 Dataset objects support context managers.

SAL01.Close()

If using an older gdal, delete or set SAL01 to None to dereference it. The dataset will be closed and written.

SAL01 = None
# or
del SAL01
