You're asking for a function to prevent the evaluation of its
arguments from throwing an error. That's fundamentally not possible
with a function call. Exception handling is a much more normal way of
handling it; though if you prefer, you could wrap it up in a function
like this:
def safe_div(num,denom):
try:
return num/denom
except ZeroDivisionError:
return 42
print safe_div(1,0) # still a poor name though
