os.path.isfile('main.txt') checks whether a file named 'main.txt' exists in the current directory and returns True if it does and False if it does not. os.path.isfile('main.py') checks whether a file named 'main.py' exists in the current directory and returns True if it does an...
python os.path.exists(path) This function returns True if a given path refers to an existing path or an open file descriptor. However, it will return False value if the given path is referring to a broken symbolic links. Moreover, on some platforms, this function may return False if th...
importosprint(os.path.exists('your_file.txt'))# Output:# True if the file exists, False otherwise. Python Copy In this example, we’re importing theosmodule and using theexists()function from theos.pathmodule. We pass the name of the file we’re checking for as a string argument to th...
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('....
例如我们可以使用os模块的os.path.exists()方法来检测文件是否存在: importos.path os.path.isfile(fname) 如果你要确定他是文件还是目录,从 Python 3.4 开始可以使用 pathlib 模块提供的面向对象的方法 (Python 2.7 为 pathlib2 模块): frompathlibimportPathmy_file=Path("/path/to/file")ifmy_file.is_file...
