very newbie question about exception handling

[Louis.Soninhu]

code sample:
----------------------------------------------
i=input()
try:
x=int(i)
print "you input an integer"
except ValueError:
print "you must input an integer"
------------------------------------------------
when I input a value like, b
I got the traceback message instead of proper exception handling:

NameError: b is not defined

I also tried

code sample:
----------------------------------------------
i=input()
try:
x=int(i)
print "you input an integer"
except ValueError:
print "you must input an integer"
------------------------------------------------
when I input a value like, b
I got the traceback message instead of proper exception handling:

NameError: b is not defined

I also tried
------------------------------------------
try: x=int(i)
except ValueError: print "something"
except NameError: pting "something"
else: print "something"
----------------------------------------------------
It still couldn't capture the exception, just the same traceback error
msg.

I'm really confused, any suggestions please?

Yes, you must use raw_input() (check the manual on "input()").

code sample:
----------------------------------------------
i=input()
try:
x=int(i)
print "you input an integer"
except ValueError:
print "you must input an integer"
------------------------------------------------
when I input a value like, b
I got the traceback message instead of proper exception handling:

NameError: b is not defined

And did you look at the traceback to see which LINE raised the
exception...

Then look at the manual for the difference between input() and
raw_input().
