[Tutor] string integers?

[William Stewart]

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
import math
int1 = int(raw_input(""))
print str1,
print str2,
print int1, "*", int2
print "="

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
hellohi45
 
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.

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.

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.

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
