| | You would run an existing python program file from DOS. The file would be created using a text editor, just like any other text file. You can not use IDLE, which comes with Python, since is requires a GUI. Some [url=http://www.freenetpages.co.uk/hp/alan.gauld/tutstart.htm]useful info[/url].

| | From a thread on another forum, I wondered how difficult it would be to create a Tic-Tac-Toe game that could not be beaten. Since it is easiest if the computer goes first and chooses the center square, this code implements that portion. The logic is fairly simple; occupy the center …  |

| | [QUOTE=;][/QUOTE] The simple method is to split on the space and then on the colon. I will leave it up to you to organize the output. [code]test_list=["name:bob grade:a dob:1980","dob:1976 name:kate grade:c"] for substr_1 in test_list: print "-"*30 first_split =substr_1.split() for substr_2 in first_split: print substr_2.split(":") [/code] |

| | Pass the dictionary to all of the functions, as that is what you are operating on. Something like [code]def add_student(student_dict): ## the while() loop is only necessary for the Yes/No input add_student="x" while add_student not in ["Y", "N"]: add_student = input('Add Student[s]? Y/N: ') add_student = add_student.upper() if add_student == … |
 | [QUOTE=;][/QUOTE] [quote]because the window doesn't go to the front[/quote]You possibly want to provide a takefocus=True parameter, but I have no idea what widget you mean by "window". Without code your questions make no sense. Both SMTP and webbrowser work on my Slackware box. |

[code] def do_something(x, y) : # Code return True self.mainWindow.hide() self.secondWindow.show() isdone = do_something(x, y) ## isdone is always True so secondWindow is always hidden if isdone : self.secondWindow.hide()[/code]And Tony is correct. Your indentation is terrible. If you want … |
| | [QUOTE=;][/QUOTE] Pyguy62 is correct about the button call back. To send arguments to a function from a Tkinter callback you use partial. [code]from functools import partial for item in options : Button(self.wdw, text= item, command= parital(self.escolha, item=item)).pack()[/code][quote]My problem is that when I launch the second window with the options my … |

| | [QUOTE=;][/QUOTE] Check out the difference between [url=http://docs.python.org/library/copy.html]copy and deepcopy as well[/url]. You probably want deepcopy (not a copy, and not a reference pointer to the list) since b is a list of tuples [code]a=[[(34,5),(34,6)],[(35,5),(35,6)]] b=[(36,5),(36,6)] a.append(copy.deepcopy(b))[/code] |

| | [QUOTE=;][/QUOTE] The Tkinter keyword is "image" not "self.image"; see the example [url=http://effbot.org/tkinterbook/label.htm]here[/url]. Also, a label is usually in a frame or some other container. Finally, you can not mix grid() and pack() so choose one or the other. [code]gmail=PhotoImage(file='gmail.gif') self.lab=Label(image=gmail) self.lab.photo=gmail self.lab.pack() [/code] |

| | [QUOTE=;][/QUOTE] You would bind <TAB> to a function that would set the focus to the next button. The program would then know which button the <RETURN> should be bound to. See the examples at this [url=http://www.ferg.org/thinking_in_tkinter/all_programs.html]page[/url]. The program becomes more complicated if you also want to include a button click … |

| | [QUOTE=;][/QUOTE] Use instance variables (self.) instead of global variables. Also, you can clean the program up by combining all of the number buttons into one for() loop and pass the number to a common function. [code]import wx from functools import partial class jake(wx.Frame): def __init__(self,parent,id): self.foo="" self.outp=0 wx.Frame.__init__(self,parent,id,'Virtual Bank', size=(500,550)) … |
| | [QUOTE=;][/QUOTE] AFAIK the Tkinter text widget is the only widget that will do sub/super-scripts. You would have to use a gif of the text or some other nasty work around to do it. |

 | [QUOTE=;][/QUOTE] Computers use numbers not strings. To check for a certain user I would use os.getuid(); root=0 and all other users=some other number. You can print the value for the halton user to find that user's number. I think the hack to get the name is something like pwd.getpwuid(os.getuid())[0] Also, … |

| | [QUOTE=;][/QUOTE] I would suggest that you print "ab" prior to the search. Since it is not passed to the class, the class has no idea what it is.

| | [QUOTE=;][/QUOTE] A numpy array is accessed by row and column. Add some print statements to find out what the data looks like. Also, a numpy array is overkill. Read the records one by one and store/calculate the values. Start with some sample data that is small, say 10 records, so … |

You would use something like … |

| | [QUOTE=;][/QUOTE] It has nothing to do with class instances, but with the self.destroy which shuts down wx. If you want to destroy/close one object only, then you must first create the object and then close/destroy it only. There is a "Starting wxPython" at the top of the threads that has … |
| | Re: Class help [QUOTE=;][/QUOTE] "self" is just a reference to the class, so that the class knows that the function or variable is in it's name space, so you have to include it when calling a function of the class from/within the class, otherwise the compiler will default to looking outside of the … |
