Python file object provides methods and attributes to access and manipulate files. Using file objects, we can read or write any files. Whenever we open a file to perform any operations on it, Python returns a file object. To create a file object in Python use the built-in functions, such as open() and os.popen(). IOError exception is raised when a ...
In Python, there are three different categories of a file object, which are listed below: 1. Text files 2. Binary files 3. Raw files All file types objects are defined in the io module.
File object has the following attributes that we can use to accessing various details of a file, such as a file name and under which mode the file is opened. 1. name: Return the name of the file. It is a read-only attribute and may not be present on all file-like objects. If the file object was created using the open()function, the file’s name is r...
File object has the following methods that we can use to accessing a file: A file can be opened with a built-in function called open(). This function takes in the file’s path and the access mode and returns a file object. Read More: 1. Open a file in Python 2. Create a file in Python Let’s see each method one by one.
In Python, a file object is an object exposing an API having methods for performing operations typically done on files, such as read() or write(). In the question's example: simplejson.load(fp, ...) , the object passed as fp is only required to have a read() method, callable in the same way as a read() on a file (i.e. accepting an optional parameter size and returning either a str or a bytes ...
