Hello
I'm a beginner to python. I ran following code and expected [[1, 0], [0, 0],
[0, 0]]
However unexpected result came up. Anybody who can teach me why and how to
solve?
Python 3.2.3 (default, May 19 2012, 23:34:41)

I agree with Peter's answer. I'd just like to add a generally useless
and pedantic comment about the habit of saying "DOS prompt". The cmd

creates a list, a, which contains the list object [0, 0] three times.
What's crucial to note is that it contains *the same object* three times,
not three different objects with the same value. You can verify
Hi everyone, trying to write a program that has the user enter a password,
checks if it contains any vowels, and if it does prints ' It is false that
password(whatever the user enters) has no vowels,' and if it has no vowels
prints it is True that password has no vowels...
Here is what I have so

Hi Mara,
Several suggestions:
Put the password in a list, then loop each letter to check if it is a vowel
like this
password=[]
vowels=['a','e','i','o','u']#in your message, u is missing, BTW
password=input("Enter a password:")
for p in password:
if p in vowels:
return

No need to make it a list, strings are already iterable. And you don't
make it a list in the code, just in the remark above.

Yes, but the problem is that Windows now has so many command prompts
(cscript, cmd, power shell etc) that "the Windows prompt"

Dear Sunil,
No method or function in Python has a *static* return type. That's
because Python is by nature a dynamic language, with duck typing and
dynamic dispatch. In fact, any method or function may well return any
of a number of different types:
