Working with Pycairo, I create an "SVGSurface" (which create for me an svg file) and I write on it using a "context". Now after I finish, I need to use the svg file, but it seems that the file is not closed so that it gave me an error telling that the document is empty.
ps = cairo.SVGSurface("header.svg", width, height)
cr = cairo.Context(ps)
drawRectangle (cr,
papersize.convert_length(int(lg[0]), "px","pt"),
papersize.convert_length(int(lg[2]), "px","pt"),
papersize.convert_length(int(lg[1])-int(lg[0])-1, "px","pt"),
papersize.convert_length(int(lg[3])-int(lg[2])-1, "px","pt"),
0, 0, 0.5
)
cr.show_page()
head = st.fromfile("header.svg")
It gives me this error :

I tried to close the file with os but it didn't work
