The open() function is essential for working with files in Python. The filename and mode parameters are passed to the open() function. There are four different ways to open a file (modes): "r" stands for Read and is the default setting. Opens a file for reading; if the file does not exist, an error is returned.
r for reading – The file pointer is placed at the beginning of the file.
r+ Allows you to read and write to a file.
w Only allows you to write to a file.
w+ Allows you to write and read a file.
rb Opens a file in binary format for reading only.
Files are used to permanently store data on a storage device. File handling is a mechanism for storing a program's output in a file and performing different operations on it. A stream is a type of abstraction that describes a device that performs input and output actions.
