Fortunately, Python has built-in functions to create and manipulate files, either flat files or text files.
Python file modes updating
You can do most of the file manipulation using a file object.
Before you can read or write a file, you have to open it using Python's built-in open() function.
This chapter covers all the basic I/O functions available in Python.
For more functions, please refer to standard Python documentation.
Take note that only the filename parameter was specified, this is due to the "read" mode being the default mode for the open function.
The access modes available for the will be thrown, which needs to then be caught and handled by your program to prevent it from crashing.It is important to note that Python strings can have binary data and not just text.The write() method does not add a newline character ('\n') to the end of the string − Here, passed parameter is the number of bytes to be read from the opened file.We would see how to use read() and write() methods to read and write files.The write() method writes any string to an open file.The simplest way to produce output is using the print statement where you can pass zero or more expressions separated by commas.
