Program Statement: Python program to read contents of the file using readline() method.

Program Description: We will read the characters of a files line by line using the readline() method in python.

We will use the concepts of file handling in python to read the contents of a file line by line using readline() method.

Steps to read contents of file:

• Step 1: Open the file in read mode using 'r'.
• Step 2: Read the data from the file line by line.
  • Step 2.1: Extract each line, we will use readline().
  • Step 2.2: Print each line.

Program to illustrate the solution of the problem

import time

F=open("names.dat","r")

while(True):
	data=F.readline()
	if(data==""):break

	print(data,end='')

	time.sleep(1)
F.close()

Output:

File Handling in Python Programming Language
Reading files using readLine 

In the above code, we will have opened the file named 'names.dat' using 'r' mode. We will read the contents of the file line by line using the readline() method and print it.
