python end of file

Assuming 'a.txt' contains some lines like

-------------------------------------

This is a nice world to live.

But I am not sure of many good things

--------------------------------------

x = 0
with open('a.txt') as f:
   f.readlines()
   x = f.tell()

f = open('a.txt','a')
f.seek(x)
f.write('Again Hello World')

readlines() reads the entire file & reaches the end.

f.tell() returns current location of the file pointer, which is at the end.

To cross-validate, open the file again with open(), reach the end of file using seek(x) & write there

File contents now

------------------------------------

This is a nice world to live.

But I am not sure of many good things
Again Hello World
