从文件夹Python导入和读取所有文件

大家好，我是python的初学者，我的代码有问题，我想从一个特定的文件夹导入并读取所有.BVH文件，但是该程序仅从该文件夹中提取第一个文件。这是我的代码。我使用可视化的搅拌器。

import bpy # This module gives access to blender data, classes, and functions
import os # This module provides a unified interface to a number of operating system functions.
import sys # This module provides a number of functions and variables that can be used to manipulate different parts of the Python runtime environment.

path = "C:\\Users\\PC\\Desktop\\Rotate Prototype\\filtered"
dir = os.listdir("C:\\Users\\PC\\Desktop\\Rotate Prototype\\filtered")

files = 0
for files in dir:
    if files.lower().endswith('.bvh'):
        try:

            bpy.ops.object.delete() # Deletes the cube

            bpy.ops.import_anim.bvh(filepath="C:\\Users\\PC\\Desktop\\Rotate Prototype\\filtered\\pick_001_3_fil_Take_001.bvh", axis_forward='-Z', axis_up='Y', filter_glob="*.bvh", target='ARMATURE', global_scale=1.0, frame_start=1, use_fps_scale=False, update_scene_fps=False, update_scene_duration=False, use_cyclic=False, rotate_mode='NATIVE') # We import a bvh file with the appropriate settings

            bpy.context.scene.render.fps = 72  # We configure the frame rate

            bpy.ops.export_anim.bvh(filepath="C:\\Users\\PC\\Desktop\\Rotate Prototype\\trolled\\haha.bvh", check_existing=True, filter_glob="*.bvh", global_scale=1.0, frame_start=1, frame_end=1515, rotate_mode='XYZ', root_transform_only=True) # We export the file with the appropriate settings

        except:
                print ("Couldn't open file")                
files++

您没有在for循环中使用实际文件。您每次都使用相同的硬编码路径。

也许您想要类似以下的内容？

我改名为files，file_path以更好地表示该变量中的内容。然后，我在调用中使用了该值import_anim.bvh，然后在调用中再次使用了该值export_anim.bvh。（在"_exported.bvh"该文件名的末尾添加了我的名字。我不确定自己要做什么。）

for file_path in dir:
    if file_path.lower().endswith('.bvh'):
        try:
            bpy.ops.object.delete() # Deletes the cube

            # We import a bvh file with the appropriate settings
            bpy.ops.import_anim.bvh(filepath=file_path,
                axis_forward='-Z', axis_up='Y', filter_glob="*.bvh",
                target='ARMATURE', global_scale=1.0, frame_start=1,
                use_fps_scale=False, update_scene_fps=False,
                update_scene_duration=False, use_cyclic=False,
                rotate_mode='NATIVE')

            bpy.context.scene.render.fps = 72  # We configure the frame rate

            # We export the file with the appropriate settings
            bpy.ops.export_anim.bvh(
                filepath=file_path + '_exported.bvh',
                check_existing=True, filter_glob="*.bvh",
                global_scale=1.0, frame_start=1, frame_end=1515,
                rotate_mode='XYZ', root_transform_only=True)

        except:
            print ("Couldn't open file")
