I would like to use a try except to see if a value exists. But, when
I use the following, if a does not exist it exits. I understand why
this does this, but is there a way to get b,c, and d if a does not
exist without using a try except for every statement?
try:
fo.write("a = %s\n" %plan.a)
fo.write("b = %s\n" %plan.b)
fo.write("c = %s\n" %plan.c)
fo.write("d = %s\n" %plan.d)
except AttributeError:
pass
def foo(obj, attr):
val = getattr(obj, attr, None)
if val is not None:
obj.write("%s = %s\n" % (attr, val))
foo(plan, "a")
foo(plan, "b")
foo(plan, "c")
foo(plan, "d")
