Hi,
The following example works for me - 2 styles are in the output Mapfile.=
Maybe there is an issue elsewhere?
Is there a Python error, or is the output not what you are expecting?
import mapscript
m =3D mapscript.fromstring("""
MAP
LAYER
NAME "test"
TYPE POINT
CLASS
NAME "0"
STYLE
COLOR 0 0 0
SYMBOL 1
SIZE 13
END
END
END
END
""")
lyr =3D m.getLayerByName('test')
cls =3D lyr.getClass(0)
style =3D mapscript.styleObj()
style.color.setRGB(0, 0, 0)
style.symbol =3D 1
style.size =3D 3
cls.insertStyle(style)
print(m.convertToString())
For Mapfile manipulation in Python you could also try https://pypi.org/p=
roject/mappyfile/
Regards,
Seth
