python：如果在交互模式下阻塞，如何退出

Question

just play with Python, a small question on interactive mode.

steps:

1. enter python interactive mode, following line shows detail on interactive mode List item
2. >>>flag=True
3. >>>if flag:
4. . . . print("flag is True")
5. after above step, i WANT to exit the whole if block. but if press enter for above line 4, it will start line with "...", which means still in if block.

question: HOW CAN I exit if block and write sth like the following in interactive mode :

flag=True
if flag:
    print("flag is True")
print("exit if now ")
