is this really a syntax error?

[Skaperen]

if i run this from a file it works as expected. if i type the same code into interactive python, i get a syntax error. which is the mistake? is this really a syntax error?

Output:

     1	foo = []
     2	for x in foo:
     3	    print('hi')
     4	print('bye')
