File Handling(read() method)

Definition and Usage

Python provides the various function to read the file, but we will use the most common read() function. It takes an argument called size, which is nothing but a given number of characters to be read from the file. If the size is not specified, then it will read the entire file.

Syntax:

file.read()

Parameter Values:

Parameter : size

Description : Optional. The number of bytes to return. Default -1, which means the whole file.

Hello! Welcome to demofile.txt
