My first 'real' program

Sorry for posting this... this is the first time i make a program that really looks like a program(well.. not really) so I need a little advice or comment.. there's may be a mistake in the program..please say something so I can make an improvement... this program just convert a number to either CM or INCH( I'm sure about accuracy)... if you put the number on CM box it'll conver to inch and vice versa... comment please.. thanx

the code

Code:

from wxPython.wx import *

class testdialog(wxDialog):
    def __init__(self,parent,ID,title,pos,size):
        id = wxNewId()
        wxDialog.__init__(self,parent,id,title,pos,size)
        panel = self
	#Label
        wxStaticBox(panel,-1,'Cm Value',(3,3),(120,43))
	wxStaticBox(panel,-1,'Inch Value',(3,48),(120,43))
	#Text Entry
        self.cm = wxTextCtrl(panel,-1,'',(14,18))
        self.inch = wxTextCtrl(panel,-1,'',(14,63))
	#Buttons
        wxButton(panel,10,'Count',(3,100),(120,25))
        wxButton(panel,11,'Clear',(3,125),(120,25))

        EVT_BUTTON(self,10,self.Count)
	EVT_BUTTON(self,11,self.Clear)

    def Count(self,event):
        cm = self.cm.GetValue()
        inch = self.inch.GetValue()
	try :        
            if cm=='' and inch=='':
                warning = wxMessageDialog(self,'Cannot process empty string','Error',
                                          wxOK|wxICON_INFORMATION)
                warning.ShowModal()
                warning.Destroy()
            elif cm !='' and inch!='':
                warning3 = wxMessageDialog(self,'Enter singe value only','Error',
                                          wxOK|wxICON_INFORMATION)
                warning3.ShowModal()
                warning3.Destroy()
                self.cm.Clear()
                self.inch.Clear()
                
            elif inch == '':
                inch_1 = float(cm)/2.54
                inch_a = round(inch_1,2)
                self.inch.WriteText(str(inch_a))
            elif cm == '':
                cm_1 = float(inch)*2.54
                cm_a = round(cm_1,2)
                self.cm.WriteText(str(cm_a))
        except ValueError:
            warning2 = wxMessageDialog(self,'Please enter numerical value(s) only','Error',
                                       wxOK|wxICON_INFORMATION)
            warning2.ShowModal()
            warning2.Destroy()
            self.cm.Clear()
            self.inch.Clear()           
            
	
    def Clear(self,event):
	self.cm.Clear()
	self.inch.Clear()
       	
           
class okrun(wxApp):
    def OnInit(self):
        return True

app = okrun(0)
dlg = testdialog(NULL,-1,'MIGHTconv v1(b)',(200,200),(132,180))
dlg.ShowModal()       
dlg.Destroy()

Note: In order to use this program, you need Python and wxPython.

I can't really offer any advice, because I haven't really used wxPython yet.

Well, lets go through a list of things:

1. The box was successfully made.
2. The labels are there.
3. When I click on 'Count' without any data, I get the correct error message: "Cannot process empty string"
4. When I click on 'Count' with data in both fields, I get the correct error message: "Enter single value only"
5. When I enter letters into one of the fields, I get the correct error message: "Please enter numerical value(s) only"
6. When I click on 'Clear', it deletes all data in both fields.
7. The correct title is in the title bar.

So far, everything is working. The only thing that wasn't quite right, was the math. The math was close, though. Maybe your math is right. Hopefully a mathematician can help us out with this one. If your math is wrong, maybe try using the math module.

Anyways, nice program!
