  Thanks to all in the group. Mini_calc is now up and running successfully 
and is now available to download from my site.

  Thanks again,
  Nathan

cal_opt = int(raw_input(What option would you like: ))
  
   Here you get the input and convert it to a number (int() )
   which is fine.
  
if cal_opt == 1:
  
   But here you compare it to a string (see the quotes).
  
   So either remove the convertion to int() around raw_input or
   remove the quotes around the values. The things you compare
   must be the same type.
  
That's not an option. Try again.
Option: 3
3*4
12
  
   I'm not sure how the multiplication appeared though!

Nathan Pinno napsal(a):

  
  
  
  
cal_opt = int(raw_input("What option would you like: "))
if cal_opt == "1":
   ..

  



your problem is in these two lines (and even more, but if you solve
this, the others you get for free).
try run just these two lines and guess, think about what kind of
variable is in cal_opt.



  
elif cal_opt == "2":
 X = input("First number:" )
 Y = input("Second number:" )
 print X, "-", Y, "= ",X - Y
 cal_opt = int(raw_input("Option: "))

  

the other trouble might be on the last line - note that "if" is not
"while". :-)

before creating your own program would be better to go through some
nice tutorial, to get some experience.

nice pytime
