Importer function issue with a loop

[remysompayrac]

Good morning,
I'm trying to make a loop with the importer add-on and I copied, pasted your code to import a dxf block into my dxf.
It works out perfectly :) But I would like to make a function depending on the dimension of the block to be imported.
It would read the file corresponding to the right dimension that I have created and import it to my dxf in Python.

However, when I try to create that function or even make a loop with for or while, an issue appears :

"importer is not callable"

or

"UnboundLocalError: cannot access local variable 'Importer' where it is not associated with a value"

What to do ?
Thank you in advance for your reply :) I love your work and your contribution to programming.

def porte(largeur):
    if largeur > 58 & largeur <= 68 :
        largeur = 63
    elif largeur > 68 & largeur <= 78 :
        largeur = 73
    elif largeur > 78 & largeur <= 88 :
        largeur = 83
    elif largeur > 88 & largeur <= 98 :
        largeur = 93
    #sdoc = ezdxf.readfile('P_' + largeur+'.dxf')
    sdoc = ezdxf.readfile(f'P{largeur}_droite.dxf')
    tdoc = ezdxf.new()
    Importer = Importer(sdoc, tdoc)
    # import all entities from source modelspace into modelspace of the target drawing
    Importer.import_modelspace()

    # import all paperspace layouts from source drawing
    Importer.import_paperspace_layouts()

    # import all CIRCLE and LINE entities from source modelspace into an arbitrary target layout.
    # create target layout
    tblock = tdoc.blocks.new('SOURCE_ENTS')
    # query source entities
    ents = sdoc.modelspace().query('CIRCLE LINE')
    # import source entities into target block
    Importer.import_entities(ents, tblock)
    PORTE = tdoc.blocks.new(name='PORTE')
    # ajouter des lignes
    #line = P_83.add_line((0.83, 0), (24.31, 58.69))
    # This is ALWAYS the last & required step, without finalizing the target drawing is maybe invalid!
    # This step imports all additional required table entries and block definitions.
    Importer.finalize()
    
    tdoc.saveas(f'PORTE_{largeur}.dxf')

Just don't redefine the Importer class 😄:

def porte(largeur):
    if largeur > 58 & largeur <= 68 :
        largeur = 63
    elif largeur > 68 & largeur <= 78 :
        largeur = 73
    elif largeur > 78 & largeur <= 88 :
        largeur = 83
    elif largeur > 88 & largeur <= 98 :
        largeur = 93
    sdoc = ezdxf.readfile(f'P{largeur}_droite.dxf')
    tdoc = ezdxf.new()

    ### Don't redefine the Importer class!
    importer = Importer(sdoc, tdoc)
    importer.import_modelspace()

    importer.import_paperspace_layouts()
    tblock = tdoc.blocks.new('SOURCE_ENTS')
    ents = sdoc.modelspace().query('CIRCLE LINE')
    importer.import_entities(ents, tblock)
    PORTE = tdoc.blocks.new(name='PORTE')
    importer.finalize()
    
    tdoc.saveas(f'PORTE_{largeur}.dxf')
