For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
full traceback log from exceptions
Exceptions example from a Well House Consultants training course
More on Exceptions [link]

This example is described in the following article(s):
   • Reporting the full stack trace when you catch a Python exception - [link]

Source code: attempt Module: Y109
# full traceback log from exceptions

import traceback

while True:
        a = input("Say summat ")

# Example - picking up a very specific exception

    except ZeroDivisionError:
        print "The art of the infinite is not available this week"

# Another special case - we mustn't retry once we have EOF

    except EOFError:
        print "Aw ... I can't win. I must doze."
        a = "Nothing available"

# Most General exceptions

    except Exception,e:
        print dir(e)
        print e.message
        print e.__class__.__name__

# A keyboard interrupt is at a higher level, so we'll catch it separately

    except KeyboardInterrupt:
        print "Can't kill me this way"

# Only get here at EOF or at proper input

print "Phew! ",a
