I don't know of one. This code requires a radial coordinate.

Here's a possibility: [code=Python]import string numbers = set('1234567890') alpha = set(string.ascii_letters) mixed = numbers.add(alpha) f = open(file_name) for i, line in enumerate(f): # i is the line number beginning with 0 s1 = set(line.strip()) if s1.issubset(numbers): # do something elif s1.issubset(alpha): # do something elif s1.issubset(mixed): # do something else: …

This may give you some ideas: [code]>>> 'abcdefg'.count('a') 1 >>> import string >>> string.ascii_lowercase 'abcdefghijklmnopqrstuvwxyz' >>> s = 'I have to write a program that will decode a Ceasar cypher with any possible rotation length' >>> dd = dict(zip(string.ascii_lowercase, [s.count(c) for c in string.ascii_lowercase])) >>> dd['e'] 8 >>> [/code]

I suggest using a dictionary. Using name "seq" instead for "list" avoids masking built-in function [I]list()[/I].[code]>>> seq = ['v', 3.0,1, 'etc'] >>> dd = {} >>> for item in seq: ... v = dd.get(type(item), 0) ... dd[type(item)] = v+1 ... >>> [dd[obj] for obj in (int, float, str)] [1, 1, …

Excellent snippet vegaseat. The expanded event handler solves a common problem.

You cannot place a menubar inside a canvas. A menubar goes on the top level window by design. You can place Tkinter widgets on a canvas by using a canvas window object.

[I][B]str[/B][/I] method [I]strip()[/I] will remove leading and trailing whitespace characters. If a string only has whitespace characters, [I][B]strip()[/B][/I] will remove them all and it will evaluate False. Example:[code]>>> not 'abcdefg12345 '.strip() False >>> not ' '.strip() True >>>[/code]

Following is an example where I already have defined a list of text strings (self.btnList) to be displayed on buttons. When a button is selected (actually, the sequence is ButtonRelease), the button text is assigned to instance attribute "value" and the app is destroyed. In your case, you want to …

Create a Tkinter.Frame to hold the checker board and another frame to hold the buttons. Pack the frames "top". If you want the buttons along the bottom, pack "left". Add internal padding to each frame to get the desired space. To eliminate duplication, initialize a list and iterate on columns …

cnuzzo, I don't want to rework your code to make it work. Instead, I will give you an example that I think you can apply to your situation in a similar way. I will only create one top level window however. It works like this: [LIST=1] Create the top level …

If the data isn't too large, consider storing it in a dictionary. It could work like this:[code]s = '''ID1 ID2 Dist 1 a 50 2 b 20 3 c 10 2 c 100 4 c 80 4 a 70 1 a 90 2 a 34 3 b 5 2 b …

Initialize your widget attribute [I]textvariable[/I] with [I]StringVar()[/I]. Use [I]w.set()[/I] to set the value and [I]w.get()[/I] to get the value.

I assume variable [I]char[/I] is a series of words. Iterate on [I]chars[/I] as in:[code]for letter in char: if letter.isalpha(): if letter in dict: dict[letter] = dict[letter] + 1 else: dict[letter] = 1[/code] BTW, please use code tags next time.

You could use a combination of re and split. Find and remove all items in quotes first then split on space. Example: [code]import re s = '''10471 'AGHADA71' 20.00 2 0.00 0.00 1 1 1.0106 0.312 'AGGTREW 45' 10475 'AGHADA75' 21.00 2 0.00 0.00 1 1 0.9940 -1.217 10810 'AHANE …

It appears that the first point is constant. Create a list of second point objects, then iterate on the list. [CODE]pointList = [Point(200, 200), Point(150, 200), ............... ] for pt in pointList: Line(Point(100, 100), pt).draw(win)[/CODE]

If you want to determine if a number is prime or not, you should return True (if prime) or False (if not prime). Use the modulo operator to determine if the entered number is divisible by loop variable [I]i[/I]. [code=Python]if not n%i:[/code]If the statement evaluates True, return False. If the …
