Answer 1

Tilde expansions doesn't work inside open(). So python won't be able to expand ~ to /home/user

A solution would be to read HOME environmental variable using os.environ

import os

home = os.environ['HOME']
file = open( home + "/.boto", "w") 
file.write("test")
file.close()

OR

Using os.path.join and os.environ

>>> import os
>>> filename = ".boto"
>>> os.path.join( os.environ['HOME'],  filename)
/home/user/.boto
