Why can't I execute such code in my Python shell? [closed]

Why am I not able to run the following lines in my shell?

>>> try:
...     x = int("a lot")
... except items["error"] as e:
...     # Same as except ValueError as e
...     prin开发者_如何学Got("Couldn't convert")

Error message:

>>> try: ... x=int("a lot") File "<stdin>", line 2 x=int("a lot")<&>
         ^ 
IndentationError: expected an indented block

Works for me:

>>> items = {}
>>> items["error"] = ValueError
>>> try:
...     x = int("a lot")
... except items["error"] as e:
...     print "Couldn't convert"
...
Couldn't convert

Your indentation is wrong. Should be:

>>> try:
...     x = int("a lot")
... except items["error"] as e:
...     print("Couldn't convert")
