使用python将相似的PDF文件分组到文件夹中

import os
import shutil
import filecmp

def are_files_similar(file1, file2):
    return filecmp.cmp(file1, file2)

def group_similar_pdfs(directory):
    files = os.listdir(directory)
    grouped_files = []

    for file in files:
        if file.endswith(".pdf"):
            file_path = os.path.join(directory, file)
            grouped = False

            for group in grouped_files:
                if are_files_similar(file_path, group[0]):
                    group.append(file_path)
                    grouped = True
                    break

            if not grouped:
                grouped_files.append([file_path])

    for group in grouped_files:
        group_folder = os.path.join(directory, "Group " + str(grouped_files.index(group) + 1))
        os.makedirs(group_folder)

        for file in group:
            shutil.move(file, group_folder)

group_similar_pdfs("path/to/pdf/files/directory")
