With Tkinter (if you are using Tkinter) it would be something like text.insert(INSERT, "click here!", "a") or listbox1.insert() As for "refreshed automatically", there is nothing automatic. You will have to define what event causes a refresh. You can tie it to a button press or a file write, etc. Any …

Two or three print statements should do the trick. Note that string is no longer used. It should be linea=linea.split(';') instead of linea=string.split(linea,';'), etc.[code] fINI='f:\\pulldpto.ini' fINI=open(fINI,'r') while 1: linea=fINI.readline() if not linea:break linea=string.split(linea,';') print "linea after split =", linea print " setting", variabl1[string.strip(linea[0])], "to zero" variabl1[string.strip(linea[0])]=0 print " setting", variable3[string.strip(linea[0])], …

The general idea is to store the replacement values in a container like a dictionary, isolate the string that you want to test, and replace it if it is in the replacement dictionary. As stated above you could store them in a separate text file and read into a dictionary. …

Put the roll statement under one of the while loops roll = random.randint(1,6) Now, it is only executed once at the beginning of the program. Also, instead of all of the if/elif you can use a list or dictionary and increment, for example counter_list[roll] += 1 You will have to …

It could very well be overkill depending. Some more info would help, but I would suggest that you start with some of your own code to find out what you want and don't want to do. Once some of the parameters are defined, it will be an easier decision.

You would use a [6][6] list of lists.[CODE]list_6x6=[] ## outer 'matrix' junk = [] for k in range(0, 6): ## inner list with length=6 junk.append(j*6 + k) list_6x6.append(junk) for single_list in list_6x6: print single_list[/CODE]Also, you can use a dictionary instead of those if/elif.[code] if bok =='A'; index = 0 elif …

While you can use a single or double quote within Python, databases are not so forgiving. If Jim699's post works it is because of the different use of quotation marks. If that doesn't work, try[code]SQL_str = 'INSERT INTO table (column1, column2) VALUES ("start finish","now later")' cursor.execute(SQL_str) [/code]

Also you probably want to indent everything under __main__, as well as use something other than "list" as a variable name as it is a reserved word. The way you have it, the code under __main__ is executed, and when finished, the wihile loop is executed, If it makes it …

You have the right idea. To add it to your program, add another if statement to the smallest & largest calcs using your num %2==0 idea. This code is not tested.[CODE] else: if num > largest: #found new largest largest = num loc_largest = location if num < smallest: #found …

Take a look as post #3 in the "starting python" topic at the top of the topics list on the Daniweb page. Basically, it would be[CODE]def function_name(catalog_f_name, write_filename): catalog_f=sextractor.open(catalog_f_name) catalog=catalog_f.readlines() sys.stdout=open(write_filename, 'w') for star in catalog: print star['X_IMAGE'] sys.stdout=sys.__stdout__ ## this calls the function with the appropriate names function_name('Z2.cat', 'Z2X.txt')[/CODE]

The problem is that you never call the function avg.[CODE]while True: location = location + 1 num = input("enter number ") if num == "done": #check for end of input print "the largest is ", largest print "at location ", loc_largest print "the smallest is ", smallest print "at location …

I think you have something like 30 minutes to edit the post. After that it is toggled to off. I suppose to keep old posts from being edited endlessly.

[QUOTE]The standard deviation is The standard deviation is <function SD at 0x020EB630>[/QUOTE]Don't use the same name for the function and the variable returned, hence "<function SD" at 0x020EB630>

It looks like Nothing is used to declare a variable for use at a later time. Since you don't have to declare variables in Python, you should be able to just ignore it. If you want a variable to be persistent, then you will have to define it with some …

Try BitBuffer first [url]http://pypi.python.org/pypi/BitBuffer/0.1[/url] You can also use array [url]http://docs.python.org/lib/module-array.html[/url] [CODE]## "H"=unsigned short int, see the docs a1 = array.array('H') fp = open(filename, 'rb') a1.fromfile(fp, 1) print a1 a1.fromfile(fp, 1) print a1[/CODE]

Start with some code to read the file, as well as the file you want to write to. Also, how large is the input file? Hint, you will want probably want to use some kind of a container to hold the 3 items you want to write.

Generally, you would do a merge type program. Read in both files, compare and change, then write to a third file, which will be the merged file. So some pseudo-code if "hb15b01" in record, find record in second file to change (let's say it has "hb15b00"), change "hb15b00" to "hb15b01" …

You can use a while loop, something along the lines of[CODE]found = 0 while not found: print "Please use W or L to input the results of the game" print win_loss_code = raw_input('Enter W for Win or L for Loss: ') win_loss_code = win_loss_code.lower() if win_loss_code == "w": print "You …

You should increment height, otherwise it's an infinite loop. In general you want to use a for() or while() loop and append to a list on each loop. Add print statements to print what you don't get (especially 'height' and 'start').

If you are using pack(), not grid, then you want side=LEFT. See this tutorial [url]http://effbot.org/tkinterbook/pack.htm[/url]

You also want a conn.comit() after inserting.

I think this probably has to do with Python's garbage collection. The file might not be closed at the exact moment you close it. You can let the program sleep for say one second, or try putting the read() through the close() in a function and call the function. All …

rcw is a list of lists. You want to write strings to a file so you have to add one more level.[CODE]for record in rcw: bird = record.strip().split() ## add this to each record outgroup.write("%s" % (dID[bird[3]]) ## assuming this is a string ## bird is a list for field …

You would use a simple bash file for this and create an icon to the bash file. You could use python, but it would simply call bash to run the program.

You would generally use a dictionary for this (and please do not use "l", "i", or "o" for single digit variables--they look too much like numbers).

You return the string "error".

A cardinal rule is don't mix tabs and spaces for the obvious reason that everyone does not have the same tab settings. The unoffical poll for this forum is that most people use spaces only. Most editors/IDE can be set to indent with either.

At one time you could pass a float to seek() and it would convert to a long long. I don't know if that still works or not. It would be doubtful if you are using 2.6 or 3.0.
