yes, and it can differentiate its behavior between the regular launch and import

it depends on the Python version

yes, but it cannot differentiate its behavior between the regular launch and import

a code point is a point inside the code when execution stops immediately

closing an open file is performed by the closefile ( ) function

the second open ( ) argument describes the open mode and defaults to ‘w’

if open ( ) ‘s second argument is ‘r’ the file must exist or open will fail

if open ( )’s second argument is ‘w’ and the invocation succeeds, the previous file’s content is lost

lambda (x, y) = x ** y

lambda (x, y): x ** y

def lambda (x, y): return x ** y

lambda x, y: x ** y

A.VarA == 1

obj_a is obj_aa

B.VarA == 1
