我们使用os.path.join()函数来将目录路径和文件名合并成完整的文件路径,并将结果赋值给file_exists变量。 3. 输出判断结果 # 输出判断结果iffile_exists:print(f"The file{filename}exists in the directory{directory}.")else:print(f"The file{filename}does not exist in the directory{directory}.") 1. ...
file_path.is_file()用于判断该文件路径是否存在。 下面是一个示例,演示了如何使用file_exists函数判断某个目录下是否存在某一文件: directory='/path/to/directory'filename='example.txt'iffile_exists(directory,filename):print(f"{filename}exists in{directory}")else:print(f"{filename}does not exist in...
