Well I suppose it matters depending on the nature of the data you are
looking at... But small function calls tend to be the death of
interpreted languages...
>>> timeit.timeit("""
def f(y,i):
try:
return(y/(i%10))
except:
return(float("nan"))
for i in range(100):
x = f(7,i)
""")

>>> timeit.timeit("""
for i in range(100):
try:
x = 7 / (i % 10)
except:
x = float("nan")
""")
