can somebody explain me the difference between accessing attributes via
obj.attribute and getattr(obj, "attribute")?
Is there a special reason or advantage when using getattr?
You use getattr when the attribute name comes from a string, rather
than a literal. There's no advantage to it when you know ahead of time
what attribute you're looking for. It's useful when you iterate over
dir(), for instance:
print("You can call...")
n=0
for attr in dir(x):
if callable(getattr(x,attr)):
print("x.%s()"%attr)
n+=1
print("...",n," options.")
