One of the simplest ways to check if a file exists in Python is by using theos.path.exists()function. This function is part of theosmodule, which provides a portable way of using operating system dependent functionality, such as reading or writing to the file system. Theos.path.exists()fun...
Checking if a File Exists This is arguably the easiest way to check if both a file existsandif it is a file. importos os.path.isfile('./file.txt')# Trueos.path.isfile('./link.txt')# Trueos.path.isfile('./fake.txt')# Falseos.path.isfile('./dir')# Falseos.path.isfile('....
importcheck_file# 检查文件是否存在ifcheck_file.exists("example.txt"):# 获取文件大小file_size=check_file.get_size("example.txt")print("文件存在,大小为:",file_size,"bytes")else:print("文件不存在") 1. 2. 3. 4. 5. 6. 7. 8. 9. 上述代码中,我们首先使用exists函数检查文件是否存在,如果...
ifmy_file.is_dir():# 指定的目录存在 如果要检测路径是一个文件或目录可以使用 exists() 方法: ifmy_file.exists():# 指定的文件或目录存在 在try 语句块中你可以使用 resolve() 方法来判断: try:my_abs_path=my_file.resolve()exceptFileNotFoundError:# 不存在else:# 存在...
Python 3.4以后引入了pathlib模块,提供了Path对象来处理文件路径。我们可以使用Path对象的exists()方法来判断文件是否存在。 示例代码如下所示: frompathlibimportPathdefcheck_file_exists(filename):path=Path(filename)ifpath.exists():print("文件已存在")else:print("文件不存在")# 测试文件是否存在check_file_exi...
If you don’t want to raise an Exception, or you don’t even need to open a file and just need to check if it exists, you have different options. The first way is using the different methods inos.path: os.path.isfile(path): returns True if the path is a valid file ...
The method is_file() is then used to check if the file exists. The syntax of is_file() is as given below. python is_file() This method will return True if the path points to a regular file or a symbolic link pointing to a regular file, and False otherwise. Moreover, it may ...
os.path.exists(test_file.txt)#Trueos.path.exists(no_exist_file.txt)#False 判断文件夹是否存在 importos os.path.exists(test_dir)#Trueos.path.exists(no_exist_dir)#False 可以看出用os.path.exists()方法,判断文件和文件夹是一样。 其实这种方法还是有个问题,假设你想检查文件“test_data”是否存在,但...
