How can I write a try
/except
block that catches all exceptions?

You can but you probably shouldn’t:
try: do_something() except: print("Caught it!")
However, this will also catch exceptions like KeyboardInterrupt
and you usually don’t want that, do you? Unless you re-raise the exception right away – see the following example from the docs:
try: f = open('myfile.txt') s = f.readline() i = int(s.strip()) except IOError as (errno, strerror): print("I/O error({0}): {1}".format(errno, strerror)) except ValueError: print("Could not convert data to an integer.") except: print("Unexpected error:", sys.exc_info()[0]) raise
