DATA FILE HANDLING. Give one difference between Text file and Binary File. Ans. Text file contains EOL character at the end of every line, there is no such character in binary file. 2. Write a Python statement to open a text file “DATA.TXT” so that new contents can be written on it. Ans. = open(„DATA.TXT‟,‟w‟)
Closing Files in Python •After processing the content in a file, the file must be saved and closed. To do this we can use another method close() for closing the file. This is an important method to be remembered while handling files in python. •Syntax: file_object.close() string = "This is a String in Python" my_file = open(my_file_name.txt ...

Text File: Text file usually we use to store character data. For example, test.txtBinary File: The binary files are used to store binary data such as images, video files, audio files, etc.A file path defines the location of a file or folder in the computer system. There are two ways to specify a file path. 1. Absolute path: which always begins with the root folder 2. Relative path: which is relative to the program's current working directory The absolute path includes the complete directory list required to locate the file. For exam...
To read or write a file, we need to open that file. For this purpose, Python provides a built-in function open(). Pass file path and access mode to the open(file_path, access_mode)function. It returns the file object. This object is used to read or write the file according to the access mode. Accesss mode represents the purpose of opening the file....
To write content into a file, Use the access mode wto open a file in a write mode. Note: 1. If a file already exists, it truncates the existing content and places the filehandle at the beginning of the file. A new file is created if the mentioned file doesn’t exist. 2. If you want to add content at the end of the file, use the access mode ato open ...
The seek() method is used to change or move the file's handle positionto the specified location. The cursor defines where the data has to be read or written in the file. The position (index) of the first character in files is zero, just like the string index. Example Output: The tell() method to return the current position of the file pointerfrom t...
Python has various method available that we can use with the file object. The following table shows file method.
There are several ways to cop files in Python. The shutil.copy()method is used to copy the source file's content to the destination file. Example Read More: 1. Copy Files in Python 2. Move Files in Python
In Python, the os module provides the functions for file processing operations such as renaming, deleting the file, etc. The os module enables interaction with the operating system. The os module provides rename() method to rename the specified file name to the new name. The syntax of rename()method is shown below. Example Read More: 1. Rename File...
In Python, the os module provides the remove()function to remove or delete file path. Read More: 1. Delete Files and Directories in Python 2. Delete Lines From a File in Python
A byte consists of 8 bits, and bits consist of either 0 or 1. A Byte can be interpreted in different ways like binary octal, octal, or hexadecimal. Python stores files in the form of bytes on the disk. When we open a file in text mode, that file is decoded from bytes to a string object. when we open a file in the binary mode it returns contents as ...
MORE ON FILES File objects have additional built-in methods. Say I have the file object f: f.tell() gives current position in the file. f.seek( offset [, from ]) offsets the position by offset bytes from from position. f.flush() flushes the internal buffer. Python looks for files in the current directory by default.

open(file_name [, access_mode]): returns a file object connected to the file on your disk named file_name. The access mode determines if the file will be used for input or output or both; access_mode can be one of the following strings: 'r' –for reading (input); the default. The file must already exist and it must be readable.
