Question :

What are different ways to read from a file ?

To read a file Python provides different reading methods. There are three ways to read from a file.
read ([n])
readline ([n])
readlines ()
where n is the number of bytes to be read.
The read() method just outputs the entire file if number of bytes are not given in the argument.
The readline(n) outputs at most n bytes of a single line of a file. It does not read more than one line. The readlines() returns a list where each element is single line of that file.
