    You can program your code to read data or instructions from a file and then write the data as well. writelines(lines) Write a list of lines to the file.Reading and writing files is a common operation when working with any programming language. write(s) Write string s to the file and return the number of characters written. writable() Returns True if the file stream can be written to. If size is not specified, resize to current location. truncate(size= None) Resize the file stream to size bytes. tell() Returns the current file location. seekable() Returns True if the file stream supports random access. seek(offset,from= SEEK_SET) Change the file position to offset bytes, in reference to from (start, current, end). Reads in at most n bytes/characters if specified. readlines(n=-1) Read and return a list of lines from the file. readline(n=-1) Read and return one line from the file. readable() Returns True if the file stream can be read from. Reads till end of file if it is negative or None. read(n) Read atmost n characters form the file. isatty() Return True if the file stream is interactive. flush() Flush the write buffer of the file stream. fileno() Return an integer number (file descriptor) of the file. detach() Separate the underlying binary buffer from the TextIOBase and return it. It has no effect if the file is already closed. Method Description close() Close an open file. Here is the complete list of methods in text mode with a brief description. And we have taken the example of most of the methods. In which a method to work with a Python file is given. Now we take an example and understand how to use these modes when we open the file: You have seen that in which mode you can open the file in Python. ‘+’ Open a file for updating (reading and writing) ‘a’ Open for appending at the end of the file without truncating it. If the file already exists, the operation fails. Creates a new file if it does not exist or truncates the file if it exists. Surrey Modes is described below: Mode Description ‘r’ Open a file for reading. So the file you open can open that file in many modes. But you know one more thing which is very important in the open() function. You know how to open files in python by using open ().

    > f = open("C:/Python33/README.txt") # specifying full path > f = open("myfile.txt") # open file in current directory Let’s take an example, in this we will open a file: Basically Python file open () is used to open a file. Now we will know how to open a file in Python. Hence, in Python, a file operation takes place in the following order. And after our work is done, we also have to close the file. Whenever we want to do some operation with a file. And these files reside in the local computer system. What is the file?Ī file is one in which some data/information store is kept. What is file handling in Python and how to create, write, append, read, delete files? Before knowing this, we know what the file is. You can do some operations with a file such as opening a file, reading from it, writing into it, closing it and delete it etc. In Python, there is a means of file handling. In this post, you will learn file handing (create, read, append, write, delete files in python) in python.
