ezdxfをインストールした後、次のエラー

python - pythonで簡単なランチャーを作ろうと思うのですがopen関数を使うとエラーが出てしまいます。 - スタック・オーバーフロー

以下で何となく動いている。

# (例)input file=C:/temp/tadasiidxf901.dxf
def print_entity(e):
    print("Line: ", e.dxf.start,e.dxf.end)
import ezdxf
dwg =ezdxf.readfile("C:/temp/tadasiidxf901.dxf")
msp = dwg.modelspace()
for e in msp:
    if e.dxftype() == 'LINE':
        print_entity(e)

# entity query for all LINE entities in model space
# for e in msp.query('LINE'):
#     print_entity(e)
