The following version illustrates several features of Python, such as default arguments, nested functions with lexical scoping, generators, and convenient syntax for creating sets and performing set operations such as intersection.
<lang python>def square(size=9):
def is_at_border(row, col):
# `&` is set intersection: if the set {row, col} intersects the set
# {0, size-1}, then at least one of row, col is either 0 or size-1
return {row, col} & {0, size-1}
for row in range(size):
print(' '.join(
'1' if is_at_border(row, col) else '0'
for col in range(size)
))
suqare()
</lang>
