This is the first program i have ever written and im having problems with the conversion equation for Ounces to Pounds
here is my code plz help

def Greydon():
	Ounce	   = input ('Weight in Ounces:');
	Pound	   = (1/16);
	print Ounce, 'Ounce =', Pound, 'Pound';
	

what am i doing wrong

Are you trying to do the actual math and convert ounces to pounds or just print "Ounces = (1/16) Pound"?

Also, what errors are you getting?

Thanks man for all your help, so hard getting help on forums these days...

You forgot to apply your conversion to your value. Also, python hates semicolons.

This:

Pound = (1/16);

should probably be this:

Pound = Ounce/16

def greydon():
          ounces = input('Weight in Ounces: ')
          pound = str(ounces/16)
          print 'Weight is %s lbs' % pound

IIRC Python convention is mostly lowercase with underscores.

the last line of code 'print...'
did not work, though the other conversion equation ounce/16 works just find, can you explain the last line of code to me?

Thanks again

It didn't work? That's strange, it worked in the Try Python online interpreter... (I was at school and couldn't test on a PC with actual Python)

...

Testing my code at home now. The last line is working for me, however pounds = str(ounces/16) isn't. %s is just another way of printing a string variable instead of doing print 'Weight is ", pounds, ' lbs'. It says, "Take %s and fill in the variable _____ for that placeholder", with the variable being the one after the % at the end. It works with multiple variables too. For example...

var_1 = 'Hello'
var_2 = 'my'
print '%s World, %s name is Andy' % (var_1, var_2)

would print "Hello World, my name is Andy".

Sorry I can't help with that line though, as it works for me. What version of Python are you using?
