從Python文件夾導入和讀取所有文件

Question

嗨大家我是python的初學者，我的代碼有問題我想導入和讀取特定文件夾中的所有.BVH文件，但程序只從文件夾中獲取第一個。這是我的代碼。我使用攪拌器用於可視化。

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++

您沒有在for循環中使用實際文件。 您每次只使用相同的硬編碼路徑。

也許你想要下面這樣的東西？

我將files重命名為file_path以更好地表示該變量中的內容。 然后我在對import_anim.bvh的調用中使用了該值，然后在對export_anim.bvh的調用中再次使用它。 （在那里我將"_exported.bvh"到文件名的末尾。我不確定你要做什么。）

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")

您正在使用files進行計數並在每次迭代中保存當前文件路徑。 在迭代中，您不輸入import_anim的當前文件路徑，您只使用了硬編碼文件路徑。 此外， ++不是有效的語法。

files = 0
for file_path in dir:
    if file_path.lower().endswith('.bvh'):
        try:
            bpy.ops.object.delete() # Deletes the cube
            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') # 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=file_path, 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
            files += 1
        except:
            print ("Couldn't open file: {}".format(file_path))
