Filter LINES in all LWPOLYLINE in DXF doc using python ezdxf

Filter LINES in all LWPOLYLINE in DXF doc using python ezdxf
if someone can help me by getting the LINES coordinates from a LWPOLYLINE in a dxf doc i would appreciate.I have the following code:

import sys
import ezdxf
Coordenadas = str()
Coordenadas_texto = str()

try:
    doc = ezdxf.readfile(str(arq)+".dxf")
except IOError:
    print('Erro de arquivo. Certifique-se que é um arquivo .dxf')
    sys.exit(1)
except ezdxf.DXFStructureError:
    print('Arquivo invalido ou corrompoido.')
    sys.exit(2)       

msp = doc.modelspace()
            
for insert in msp.query('INSERT'):
    block = doc.blocks[insert.dxf.name]
    for e in block:
        if e.dxftype() == 'LINE':
        
            Coordenadas = Coordenadas + str(e.dxf.start) + "\n"              
            Coordenadas = Coordenadas + str(e.dxf.end) + "\n"

the "for" above get the block "INSERT" and split them to i can get only LINES. I tried do the same thing for LWPOLYLINE but din't worked.

the code bellow get all coordinates but i need to filter and get coordinates line by line

    for flag_ref in msp.query('LWPOLYLINE'):
    for entity in flag_ref:

            print(entity)

the code bellow stoped worked suddenly, think the librarie ezdxf changed. getting me error

'LWPolyline' object has no attribute 'virtual_entities'

for flag_ref in msp.query('LWPOLYLINE'):
    for entity in flag_ref.virtual_entities():
        if entity.dxftype() == 'LINE':

            Coordenadas = Coordenadas + str(entity.dxf.start)+ "\n"
            Coordenadas = Coordenadas + str(entity.dxf.end)+ "\n"

Solved.

The last code stil working. But i am using anaconda spyder and if you install all packages for ezdxf from conda site it's subscribe this function somehow

only use conda install -c conda-forge ezdxf

The packages from conda-forge are not maintained by myself. The packages from PyPI are always up to date, at the time of writing this 0.17.2 on PyPI vs. 0.17 on conda-forge and since 0.17.2 there are much more platforms supported by binary wheels on PyPI than on conda-forge:

Version 0.17.2 - 2022-01-06: extended binary wheels support

• all binary wheels for Python 3.7, 3.8, 3.9 and 3.10
• win_amd64 for Windows
• manylinux2010_x86_64 for Python < 3.10 and manylinux2014_x86_64
  for Python >= 3.10
• musllinux_2010_x86_64 for Python < 3.10 and musllinux_2014_x86_64
  for Python >= 3.10
• manylinux_2014_aarch64 for ARM64 based Linux
• musllinux_2014_aarch64 for ARM64 based Linux
• macosx_11_0_arm64 for Apple silicon
• macosx_10_9_universal2 for Apple silicon & x86
