How To Write File In A Different Directory In Python?

I am working on Linux with python 2.7.x and I am running some programs python through terminal. I want the certain output should be written in a file located at different directory

Solution 1:

Changing the current directory with os.system will not affect the Python process that’s running. Just open the file with its full path directly:

with open('/pr/p1/ap11/All.txt', 'a') as output:
    output.write('hello\n')
