No it's not. It's a tuple unpack operator. It's commonly used in this
context:
def func1(*args, **kwargs): #func1 can take variable args
# do stuff
func2( *args ) #unpack the variable args and pass them to func2
func3( *args )
func4( *args, **kwargs)
def func2( a, b, c):
d = a + b + c
def func3 ( *args ):
pass
def func4 ( *args, **kwargs):
pass
func1(1,2,3)
