Value=input("Enter a value") problem

helllo everyone, I am quite new to Python and am currently using Python 3.3. I got stuck with the following problem. Is there anyone who can provide me with guidelines/help on the following problem?

>>>value=input("Enter a value ")
>>>Enter a value 9*9
>>>inval
>>>'9*9'

the code above should print out the result of multiplication as value being referenced by the inval , but instead '9*9' is printed out. Is there any problem with my coding? Greatly any help/ guideline that can be provided.

input() changed between Python 2 and 3 -- Python 3's input() is equivalent to Python 2's raw_input(). If you want your input to be evaluated in Python 3, you need to explicitly call eval() on it.

hello, thanks for your quick reply. But, can you show me how to explicitly call eval().

Is it like this:
value=eval("Enter a value")? or
value=raw_input("Enter a value")?

The concise way would be like this:
Code:
`value = eval(input())`

raw_input() doesn't exist in Python 3.
