Are nested try/except blocks in python a good programming practice?

Question

I\'m writing my own container, which needs to give access to a dictionary inside by attribute calls. The typical use of the container would be like this:

dic

According to the documentation, it is better to handle multiple exceptions through tuples or like this:

import sys

try:
    f = open('myfile.txt')
    s = f.readline()
    i = int(s.strip())
except IOError as e:
    print "I/O error({0}): {1}".format(e.errno, e.strerror)
except ValueError:
    print "Could not convert data to an integer."
except:
    print "Unexpected error:", sys.exc_info()[0]
    raise
