Python实现批量重命名文件夹可以通过`os`模块的`rename`方法来实现。以下是几种不同场景下的实现方式： ### 简单的批量重命名文件夹 使用`os`模块的`listdir`方法遍历指定文件夹下的所有文件夹，然后使用`os.rename`方法对文件夹进行重命名。以下是示例代码： ```python import os def batch_rename_folders(folder_path, prefix="new_"): # 获取指定文件夹下的所有文件夹 folders = [f for f in os.listdir(folder_path) if os.path.isdir(os.path.join(folder_path, f))] for folder in folders: old_folder_path = os.path.join(folder_path, folder) new_folder_name = prefix + folder new_folder_path = os.path.join(folder_path, new_folder_name) # 重命名文件夹 os.rename(old_folder_path, new_folder_path) if __name__ == "__main__": folder_path = "your_folder_path" batch_rename_folders(folder_path) ``` ### 更复杂的重命名规则 如果需要根据一些规则对文件夹进行重命名，可以参考以下示例，该示例根据文件夹名中的数字进行排序并重新命名： ```python import os def batch_rename_folders_with_rule(folder_path): # 获取指定文件夹下的所有文件夹 folders = [f for f in os.listdir(folder_path) if os.path.isdir(os.path.join(folder_path, f))] # 按照文件夹名中的数字排序 folders.sort(key=lambda x: int(''.join(filter(str.isdigit, x))) if any(map(str.isdigit, x)) else float('inf')) i = 1 for folder in folders: old_folder_path = os.path.join(folder_path, folder) new_folder_name = f"folder_{i}" new_folder_path = os.path.join(folder_path, new_folder_name) # 重命名文件夹 os.rename(old_folder_path, new_folder_path) i += 1 if __name__ == "__main__": folder_path = "your_folder_path" batch_rename_folders_with_rule(folder_path) ``` ### 批量重命名文件夹内的文件 如果需要批量重命名文件夹内的文件，可以参考以下示例： ```python import os def batch_rename_files_in_folder(folder_path, prefix="new_", suffix="_backup", replace_dict={"old": "new"}, include_ext=True): # 获取指定文件夹下的所有文件 files = [f for f in os.listdir(folder_path) if os.path.isfile(os.path.join(folder_path, f))] for file in files: old_file_path = os.path.join(folder_path, file) file_name, file_ext = os.path.splitext(file) # 进行字符替换 for old_str, new_str in replace_dict.items(): file_name = file_name.replace(old_str, new_str) # 添加前缀和后缀 new_file_name = prefix + file_name + suffix if include_ext: new_file_name += file_ext new_file_path = os.path.join(folder_path, new_file_name) # 重命名文件 os.rename(old_file_path, new_file_path) if __name__ == "__main__": folder_path = "your_folder_path" batch_rename_files_in_folder(folder_path) ```
