for i in range(0, len(sys.path)):    
    if sys.path[i].find("~") > -1:        
        sys.path[i] = path.expanduser(sys.path[i])
        break
else:    
    sys.path.insert(1,path.expanduser("~/lib/python"))

More duct tape code to allow me to rely on ~/lib/python to store common code (ex. apache log parsing & analysis ) when PYTHONPATH might not be set or
set incorrectly.

Basically if ~ is found in sys.path, the break statement skips the else. Alternatively, if not found then else is executed.
