如果目标文件夹还包含同名文件，请移动文件并重命名该文件

import os
import shutil

def move_and_rename_file(src_path, dst_folder):
    # 获取源文件的名称
    file_name = os.path.basename(src_path)
    base_name, ext = os.path.splitext(file_name)
    
    # 目标文件路径
    dst_path = os.path.join(dst_folder, file_name)
    
    # 如果目标文件已存在，则重命名
    counter = 1
    while os.path.exists(dst_path):
        new_file_name = f"{base_name}_{counter}{ext}"
        dst_path = os.path.join(dst_folder, new_file_name)
        counter += 1
    
    # 移动文件
    shutil.move(src_path, dst_path)
    print(f"Moved and renamed '{src_path}' to '{dst_path}'")

# 示例用法
src_path = 'path/to/source/file.txt'
dst_folder = 'path/to/destination/folder'
move_and_rename_file(src_path, dst_folder)
