This produces the following result − Name of the file: foo.txt Print "Softspace flag : ", fo.softspace Output Returns false if space explicitly required with print, true otherwise. Returns access mode with which file was opened. Returns true if file is closed, false otherwise. Here is a list of all attributes related to file object − Sr.No Once a file is opened and you have one file object, you can get various information related to that file. If the file does not exist, it creates a new file for reading and writing. The file pointer is at the end of the file if the file exists. Opens a file for both appending and reading in binary format. Opens a file for both appending and reading. If the file does not exist, it creates a new file for writing. Opens a file for appending in binary format. If the file does not exist, creates a new file for reading and writing. Overwrites the existing file if the file exists. Opens a file for both writing and reading in binary format.

Opens a file for both writing and reading. If the file does not exist, creates a new file for writing. Opens a file for writing only in binary format. The file pointer placed at the beginning of the file. Opens a file for both reading and writing in binary format. Opens a file for both reading and writing. The file pointer is placed at the beginning of the file. Opens a file for reading only in binary format.

Here is a list of the different modes of opening a file − Sr.No If negative, the buffer size is the system default(default behavior). If you specify the buffering value as an integer greater than 1, then buffering action is performed with the indicated buffer size. If the buffering value is 1, line buffering is performed while accessing a file.

buffering − If the buffering value is set to 0, no buffering takes place.

This is optional parameter and the default file access mode is read (r). A complete list of possible values is given below in the table.

access_mode − The access_mode determines the mode in which the file has to be opened, i.e., read, write, append, etc.

file_name − The file_name argument is a string value that contains the name of the file that you want to access.

This function creates a file object, which would be utilized to call other support methods associated with it. The open Functionīefore you can read or write a file, you have to open it using Python's built-in open() function. You can do most of the file manipulation using a file object. Python provides basic functions and methods necessary to manipulate files by default.

Now, we will see how to use actual data files. Depending on how you want the file handling methods to write to a file, you can use one of the below modes.Until now, you have been reading and writing to the standard input and output. There are multiple ways you can open a file in write mode in Python.

ab: Append binary mode for images, videos, etc.

It will create a new file if the filename does not exist.

wb: Binary write-only mode for writing to media files.

This will create a new file if the specified filename does not exist.

rb: Read-only binary mode to read images, videos, etc.

Will not create a new file and open will fail if the file does not exist So what are modes, and how do we add them? Below is a list of modes when using the open() method.
