I admit there are times I've done something similar, usually with
what I call my "int0" and "float0" utility functions which
roughly translate to "give me a stinkin' int/float and if
something goes wrong, give me 0, but the return result better
darn well be an int/float!" functions. But as you describe and
was later commended as a right-ish way to approach it,
abstracting that off into a function with minimal code in the
try: block is the right way to go.
-tkc
def int0(v):
"""converts v to a int, or returns 0 if it can't"""
try:
return int(v)
except: # usually a ValueError but catch all cases
try:
# int("1.1") fails so try float()ing it first
return int(round(float(v)))
except:
return 0
def float0(v):
"""converts v to a float, or returns 0 if it can't"""
try:
return float(v)
except:
return 0.0
