The first step is to import TemporaryFile from the tempfile module. read () # Close the file, after which it will be removed fp. write ( 'Hello universe!' ) # Go back to the beginning and read data from file fp.
#Python find file code#
Running the code above produces the following:įrom tempfile import TemporaryFile # Create a temporary file and write some data to it fp = TemporaryFile ( 'w+t' ) fp. For more information, read Python 3’s pathlib Module: Taming the File System. Another benefit of using pathlib over os is that it reduces the number of imports you need to make to manipulate filesystem paths. Using pathlib is more if not equally efficient as using the functions in os. Pathlib offers a set of classes featuring most of the common operations on paths in an easy, object-oriented way. iterdir() to get a list of all files and directories in my_directory. In the example above, you call pathlib.Path() and pass a path argument to it. pathlib was first introduced in Python 3.4 and is a great addition to Python that provides an object oriented interface to the filesystem. iterdir() contains information about the file or directory such as its name and file attributes. iterdir() method for creating an iterator of all files and folders in a directory. The objects returned by Path are either PosixPath or WindowsPath objects depending on the OS. Syntax: (path) # Example to check if a file or directory exists in Python using the pathlib moduleįile = Path("C:\Projects\Tryouts\etc\password.From pathlib import Path entries = Path ( 'my_directory/' ) for entry in entries. Pathlib is the modern and most convenient way for almost all file or folder operations in Python, and it is easier to use. This module offers object-oriented classes filesystem paths with semantics appropriate for different operating systems. The pathlib module is available in Python 3.4 and above. Print(os.path.isdir("C:\Projects\Tryouts\doesnotexists")) Print(os.path.isdir("C:\Projects\Tryouts\etc")) Print(os.path.isdir("C:\Projects\Tryouts\etc\password.txt")) Syntax: os.path.isdir( path) # Example to check if a directory exists in Python using the OS module The os.path.isdir() method in Python is to check whether the specified path is an existing directory or not.
Print(os.path.isfile("C:\Projects\Tryouts\doesnotexists")) Print(os.path.isfile("C:\Projects\Tryouts\etc")) Print(os.path.isfile("C:\Projects\Tryouts\etc\password.txt")) Syntax: os.path.isfile( path) # Example to check if a file exists in Python using the OS module The os.path.isfile() method in Python checks whether the specified path is an existing regular file or not. Print(os.path.exists("C:\Projects\Tryouts\doesnotexists")) Print(os.path.exists("C:\Projects\Tryouts\etc")) Print(os.path.exists("C:\Projects\Tryouts\etc\password.txt")) Syntax: os.path.exists(path) # Example to check if file or directory exists in Python using the OS module The os.path.exists() method checks both file and directory, and it returns true if a file or directory exists. Currently, using OS module methods, we can verify easily if a file or directory exists. Using the OS module in Python, it’s easy to interact with Operating System. Python check if a file exists using OS Module Let’s take a look at each one of these in detail. There are different ways to check if a file exists in Python. When you perform a file operation such as reading from a file or writing content to a file, we need to check if a file or directory exists before doing the i/o operation. Python check if a file exists using OS Module.
