If I call print walk([1,2,3], []) print walk([5,6,7])
I get
[1, 2, 3]
[4, 5, 6]
but when I call
print walk([1,2,3])
print walk([5,6,7])
I get
[1, 2, 3]
[1, 2, 3, 4, 5, 6]
at stdout, where
def walk(seq, result = []):
for item in seq:
result.append(item)
return result
Does that mean that the scope of optional arguments is global if they aren't
used and local if they are (or am I missing something here)?
