error with string (beginner)
Hello. I get the following error with the following code. Is there
something wrong with my Python installation?
code:
import types
something = input("Enter something and I will tell you the type: ")
if type(something) is types.IntType:
print "you entered an integer"
elif type(something) is types.StringType:
print "you entered a string"
error:
String: Source for exec/eval is unavailable

break the loop in one object and then return
I am trying to write the following code to block up evaluation and
prompting for entering new information. However, when I break the loop
in one object and then return it does not start at the beginning again
but rather at the point where it exited. Can someone look at the
following code and give me some feedback.
yournum = input("I am thinking of a number between 1 and 100.\n Guess
which number: ")
mynum = (yournum-5)
def eval():
if yournum == mynum:
print "Wow! You got it!"
elif yournum < mynum:
print "Nope. Too low"
again()
elif yournum > mynum:
print "Oh, your too high"
again()
def again():
global yournum
yournum = input("guess again: ")
eval()
eval()

Re: break the loop in one object and then return
Peter, Why do you make such claims without any reason to do so? This
is my own thing. So, I guess I am a student but just a student of my
own accord. So, please don't reply if you don't have anything to
contribute.
As for the - mynum I guess that could happen but I am just doing this
so that they will never match on first try. I guess I should just
hardcode it.
This is what happens if I step though:
mynum = 93***1***
yournum = input("I am thinking of a number between 1 and 100.\n Guess
which number: ") ***2***
def strt(): ***3******6***
if yournum == mynum: ***7***
print "Wow! You got it!"
elif yournum < mynum: ***8***
print "Nope. Too low" ***9***
again()***10*** ***15***
elif yournum > mynum:
print "Oh, your too high"
def again(): ***4*** ***11***
global yournum ***12***
yournum = input("guess again: ") ***13***
strt() ***14***
strt() ***5***
***15*** is the problem. It doesn't start at the top but rather where
is leaves the loop.

\t not working
I am just learning Python and I am using the book, "Thinking like a Computer Scientist". There is an exercise that I am not able to get working and it is really easy so I thought I would ask for help here. Q: As an exercise, write a single string that: Procuces this output. A? print "produces",'\n',"\t","this","\n","\t","output." -- http://mail.python.org/mailman/listinfo/python-list
Re: \t not working
Sorry, I just realized that if I run it as a script it just drops a line and doesn't tab but if I run it from the shell it outputs perfectly. Thanks for the help. -- http://mail.python.org/mailman/listinfo/python-list
Re: \t not working
ha ha...good point. I didn't realize that you could run it all together. I guess the "single string" part should have been a tip off. Anyway, more questions to come soon. Thanks everyone! -- http://mail.python.org/mailman/listinfo/python-list
SPE output
Does anyone know if there is a way to configure the SPE output? IDLE and Pythonwin IDE both have nicely formatted output that shows tabs and spaces correctly. SPE seems to just print out the text without any formatting. SPE is amazing with the intellisense but maybe there is a better choice out there.

"Thinking like CS" problem I can't solve
Hello. On page 124 of "Thinking like a Computer Scientist". There is an exercise to take the following code and with the use of TRY: / EXCEPT: handle the error. Can somone help me out? Here is the code: def inputNumber(n): if n == 17: raise 'BadNumberError: ', '17 is off limits.' else: print n, 'is a nice number' return n inputNumber(17) -- http://mail.python.org/mailman/listinfo/python-list
script vs inneractive
I am a little confused because I write most of my programs in a script editor but not all the code executes unless I run it from the inneractive shell. Am I doing something wrong? A good example is "return 1" in a script returns nothing where as in the inneractive shell it will return 1 or true. -- http://mail.python.org/mailman/listinfo/python-list
xcode able to run script?
Does anyone know if it is possible to test your scripts from within the xcode editor? I am currently using Uilipad on windows and there is a sub window that lets you view your output when you launch the script from within the ide. hopefully this makes sense. thanks, Alex -- http://mail.python.org/mailman/listinfo/python-list
