如何使用python根据标签移动百分比的文件？

import os
import shutil

source_folder = "源文件夹路径"
target_folder = "目标文件夹路径"
label = "要移动的文件标签"
percentage = 0.5  # 移动百分比，如50%表示移动一半的文件

files_to_move = []
for file_name in os.listdir(source_folder):
    if label in file_name:
        files_to_move.append(file_name)

num_files_to_move = int(len(files_to_move) * percentage)

import random
random_files_to_move = random.sample(files_to_move, num_files_to_move)

for file_name in random_files_to_move:
    file_path = os.path.join(source_folder, file_name)
    shutil.move(file_path, target_folder)
