Changing a line in a text file

[kah]

How do I change a line in a file??

For example I have the follwing text in my file:

line1
line2
line3
line4

How do I replace 'line2' with 'newline'. Since the write operation in
python will  overwrite everything.

Regards,
Kah

Hi,

the example provided by Vishnu is quite close to what I want but it
still required me to write all the data back to the file.

Is there any way where I can just write a particular line?

Kah
