Re: [Tutor] Python programming help!
Wow, didn't know attachments didn't work. I had posted my screenshot as an attachment, never expected you to read my mind. I solved the problem, it was a spelling mistake (I know, I'm stupid).

I don't see any problem here. If you provided an attachment this email list does not forward attachments. The proper way is to copy and paste directly into the body of the email.

Thanks, Oscar. I haven't really seen something similar for OSX, mainly because I have never used one. I searched now though on YouTube and there seems to be a few. -- http://echorand.me ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

I am a beginner in computer programming.
Hi welcome to the tutor list.
I am currently trying to write a program in Python version 2.7.5 *that
uses the math module to compute sinh(x) = 1/2(e^x - e^(-x)) in three
ways for a given value of x:*
*1a) by using the sinh function*
*1b) by using the exp function*
*1c) by using the value of e and the exponentiation operator
So, I know that I have to create a NotePad file so that I can import
that into my command prompt.
You don;t need to import it into the command prompt although
you may for that for testing purposes. But you can run Python
programs directly by double clicking them in your file explorer.
It will help if you tell us which version of Python you are using and
which Operating System you use. (I'll assume Windows in this post
since you mention Notepad)
Finally, Notepad is fine for short text notes but it's not good for
programming. You should get a proper programer's editor. IDLE comes
with Python in most cases and if you are using Windows and download
the ActiveState version of Python you will also get Pythonwin.
Either of those will be better than Notepad for writing code.
In my NotePad file, I have the following...I'm not sure if I am even
going about doing this problem correctly...
def sinh(x):
return (1/2)*(e^x - e^(-x))
The ^ sign does not do what you think in Python. The operator you
need is ** (or use the pow() function).
Also e is not defined directly, it's in the math module so you
need to import math and then reference it as math.e
Alternatively, import e from math:
>>> from math import e,exp # import e and exp() from math
And then use them directly:
>>> import math
>>> math.exp(3)
20.085536923187668
or
>>> from math import e,exp
>>> exp(3)
20.085536923187668
I am stuck, and don't know where to go from here. I would appreciate
help please.
You have defined your first version of sinh() you now need to fix
and test it. You can either import it into your python session
>>> import sinh# assuming the file is called sinh.py
>>> sinh.sinh(5) # remember to include the module name as a prefix
or
You could call the function in your file and run it by clicking in
explorer. To do that you should add to the end of your file:
print( sinh(2) ) # use any test value you wish...
input('Hit enter to quit') # pauses output so you can see it
If you are comfortable using the OS command prompt you can also
run it from there with
C:\PATH\TO\YOUR\FILE> python sinh.py
This has the advantage that you will see any error messages too.
Finally, if you use IDLE or Pythonwin you can run the
program from inside those tools using the menus. At this stage
that's probably the best option. You can get a video tutorial
on using IDLE here:

Okay, so when you are programming, there are two things you do to see the result of your programs: 1. First, you write the program. You write this in an text editor. Notepad is a text editor (There are better options, but let's keep it as it is for now) 2. Then, you run the program. Sometimes you can run the program from the editor itself, such as in IDLE. Other times, you have to run it separately. So, before you write the solution to the programming problem above, can you first try to write a program and then run it? What operating system are you working? If you are on Windows, can I suggest you to take a look at these videos I created a while back and they may help you: http://www.youtube.com/playlist?list=PLD0rs_vnIQS5r8IhNpu0rWIAyKpTX34yo Only when you have written your first program, which is really simple, you should try to attempt your exercise. Hope that helps. -Amit. -- http://echorand.me ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

You'd have done well to present the problem you're having, but you should know that ^ is XOR (as it is in most programming languages), you probably want ** (and space out your function definitions -- PEP8 says to use two blank lines between functions). pgp_uNjpYYMed.pgp Description: PGP signature ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
