Your programs are running on a random server with a cleaned environment on sololearn. You can't save files with one program and read them with a second one.

Harsha S ,
what you can do is to put both codes in one file:
1. creating / writing to a file
2. reding from the file
file = open("harsha.txt", "w")
file.write("harsha")
file.close()
file = open("harsha.txt")
print(file.read())
file.close()
as this will be executed in one session, you can store and access the created file. when the execution is terminated, the file is gone.

In the past i made a small program to see where the code was running.
If you run it more than once, you will see that you are every time on a different node:
import os
import socket
print(os.uname())
print()
print(socket.gethostname())

This is a bit off topic but may be useful to you in the future. If you write to a file as you did in the example, if there were to be an exception during the file.write() call the file might not close and may leak a discriptor. Use try and finally for write and close calls.
You can avoid all that by using the with statement.

Sololearn creates file in temporary store like cache and It will cleared after exit. Not exist in server...
