Answer 1

No need to import any special libraries to do this.

Use normal syntax and it will open the file for reading then close it.

with open("/etc/hostname","r") as f: print f.read() 

or

with open("/etc/hosts","r") as f: x = f.read().splitlines()

which gives you an array x containing the lines, and can be printed like so:

for line in x: print line

These one-liners are very helpful for maintenance - basically self-documenting.
