[Tutor] string integers?

this is the code I have
str1 = raw_input("Type in a String: ")
str2 = raw_input("Type in a String: ")
int1 = raw_input("Type in a integer variable: ")
int2 = raw_input("Type in a integer variable: ")
print str1 + str2 + int1 + int2
int1 = int(raw_input(""))
print int1, "*", int2
and it does not give me an error message when I run it, the program runs fine except its did not multiply the 2 integer variables i entered
it looks like this
Type in a String: hello
Type in a String: hi
Type in a integer variable: 4
Type in a integer variable: 5
This part is exactly what I want it to look like
except I want it to multply the 2 numbers I inputed (4 & 5 in this example)
thanks again for your time and sorry if I seem rude I just dont have alot of time these days
I know you all dont have alot of time either and thats why I am extremely appreciative of everyones help

That was a post to the list; you replied privately, but I'm going to
just elaborate my earlier points. Try again, but use reply-all to one
of the messages in the thread.
You've got a new version of stuff, but no indication what the code now
looks like, or what is "not working".
Be explicit when requesting help. I and others pointed out a few things
wrong; there are others. So don't make us guess what state you're in.
Hopefully you're here to learn, and that happens best when you make
clear questions, and get good responses.
Show your code, show the error,and use cut&paste for the error you get.
"It's not working" is not an error message.
You either get an error message: quote the entire traceback
Or it doesn't do what you expect: tell what you expected, and show
what you got instead.

> SyntaxError: invalid syntax
> So now we both know the error is a syntax error, and it occurs on line 7, which is conveniently redisplayed with a caret pointing at where the error was discovered (notice that in many email systems a proportional font may hide the correct column. So trust what you saw on your own terminal window). Sometimes the actual syntax error is a few characters earlier, but this is as fine-tuned as most compilers can manage.
> That print line has 4 errors that I can immediately spot, and the compiler told you about the first one. That error was in omitting the comma before the first occurrence of the variable int2. You butted a string literal right up to a variable name, with no operator between.
> My usual advice when seeing a beginner with a complex line that gives a syntax error is to see if you can replace it by a few simpler lines. Then the error might be more obvious. So use several print lines. So what if the output isn't quite right; you have some more debugging to do before you'll even see that output.
> Now let me ask you, how is str1 any different from int1 ? Python does not have typed variables, and it certainly pays no attention to the spelling of a name to guess what it's intended to hold. The same name str1 can hold a string one time, an integer another time, a list yet another. The only way you're going to get those 3rd and 4th lines to make integer objects is to convert the string that raw_input() returns into an integer. So use
> int1 = int(raw_input("xxxxx"))
> The next problem will probably be easier for you to spot, but if not, remember to post the full error message, not some summary of it.
