A simple way to create a toggle button for the Tkinter Python GUI toolkit.

I am a beginner in computer programming and need help with this problem: Create a script that prompts the user to provide the number of pennies, nickels, dimes, and quarters. Display back the value of the coins in dollars and cents. Here is my code so far, everything is good …

The Tkinter GUI toolkit comes with a scrolled text widget that is called ScrolledText. To get access to it you have to import it separately. It allows you to display large amounts of text in a small space.

I have basic knowledge about python. I am looking for help with this code: how is the snake moving? How does it length increases on colliding with the object? And, how does it detect when it touches itself or when it collides with the wall? It also has semicolon in …

As the title says, anyone else noticing the activity on DaniWeb suddenly dropping? I usually check the Database and Software Developing sections in the morning. The Database one for awhile was getting a few new topics at least a day, but all of a sudden, it seems to have almost …

since the forum has been quiet for a while I thought to post this program , it might start new discussions . the idea is not new but it should be interesting to starters . as usual any comments is appreciated

I found that one can use dictionaries to hold Tkinter widget config and display parameters. This then permits one to have these dictionaries elsewhere in the code for easy modification instead of buried within the code for each widget. I particularly like to place these dictionaries toward the top of …

I have been learning NumPy arrays/matrices in Python. As I worked, I found that I desired a more readable form of 3d matrices. So I figured that writing one would be a good goal and learning exercise. The goal was to create a function that would print 3d NumPy matrices …

This is the updated version of the Tiny Tkinter Calculator. It has more power, since you can type in functions contained in the Python math module then press the equals key. You can then move the result into memory for other calculations. The code is written in OOP class style …

Note: In Python 2.7 use: `from __future__ import print_function` to use examples. In Python, by default, the key and value pairs in a dictionary are stored as hashes, therefore dictionaries do not retain the order in which values were added, and cannot be ordered. v_Dict ={} v_Dict["First"] = 99 v_Dict["Second"] …

After you got the basics of Python under your belt, the best way to get a good knowledge of the language and improve your coding skills is to start on a project you are interested in. Maybe an image viewer, a slide show, computer generated random or fractal art, a …

Hello everyone I'm having trouble with this program in Python called sumList(nums). I already tried to program it, but I get the incorrect output. The program is suppose to get the summ of numbers entered into a list by the user. Mine does not return the sum just the first …

!USING PYTHON 3.1! Hello DaniWeb! Today I'm going to teach you a cool variable trick that I learned. So here's an example: [CODE] a, b, c = input('?x?x?: ').split('x') [/CODE] Now let's input something like: [CODE] >>> a, b, c = input('?x?x?: ').split('x') ?x?x?: 1x2x3 [/CODE] Now, variable 'a' is …

Needed a func to convert base 2 into 10, and back. Found the referenced code in this func for moving between three bases, and generalized it to between bases 2 and 62, and all in between. Upconvert a number, then down convert, then upconvert again. Go wild, have fun.

In my quest to learn more regarding programming in Python, I "dissect" a lot of other people's code. While doing this, or writing my own code, I end up with 10's of debug print lines. Things like this: if v_Debug == 1: print("DEBUG - ".format()) # DEBUG If I decide …

I, and many others, desired a "switch" keyword in Python. For me it was to a desire to make some of my code more compact and readable, as I often have many user selected options for the code to weed through. So I set off on a journey to figure …

So im extremely new to python. Im teaching it to myself for a school project and i heard that calculators are a good place to start so that's exactly what im doing. I have only been using it for about a day now so like i said im pretty newb. …

I needed a random color selector. I found one [here](http://peepspower.com/python-script-to-generate-random-css-colors). I rewrote it to make it more general purpose. "f_GenRandomColor" is the picker. The output is in list form, which should make it suitable for most general applications. "f_HTMLRandomColorChart" is just a way to create an HTML table to test …

One of my first programs was coded on paper tape. Another was via punched cards. I foresaw amazing stuff, e.g., artificial intelligence, models for weather, space travel, etc., but never imagined we would come this far in only 60 years. I now have a programmer son who wants me to …

When recursion won't do, then memoizaton will.

Allows multiple entries using raw_input. I often have to enter multiple items in my Python programs. I desired an easier way than using a loop(s). Today I discovered a way, and with a few mods made it happen.

Recently I started teaching teens programming. I use Python for them. An adult approached me and asked if I would teach her. The problem is that she's in her 40s, and hasn't had to think logically or algorithmically since high school, if ever. Scratch/Snap is too basic, and Python, in …

People who know me know that Python has always been one of my favorite languages. And over the years, I've been pleased with the array of development tools that have been created for it, including the different IDEs. I also do a lot of work in .NET, primarily with C#. …

I just love generators in Python. One of the cool things I found out from [this](http://nedbatchelder.com/text/iter.html) site was that one could send in a value when calling on an active generator. To do so one uses the send() method and a yield like so: "x = yield". The send with …

We have had several snippets on the format() function. This one gives a condensed overview of the many options you have.

As a result of my research in number theory I find that I often need to break a number down into its numerical parts while stepping through one divisor to another. I call this process "break factoring," as I am just breaking a number down into parts, and not necessarily …

Also because of my work in number theory, I often need to have the root floor and root ceing of a number. This is my function for computing those two numbers from a target number.

I do a lot of work in number theory, especially with factors. I often need just the two middle factors from a very long factor list/result, so I created a function that takes a factor list and returns just the middle two, or one, factors. Nothing earth shattering, but I …

Instead of using letters as substitutes for playing card suits, I came up with a way to use unicodes to produce the common suits. The following creates the coded needed, makes the deck, and then prints the deck. The printing was the hard part. Is 2.7, and should be 3.0+ …

My code and funcs for printing to columns in 2.7 and 3.0+ using print(). I had to relearn column formatting as I moved to using the print() function, and so the follwing is a result. Inspired and partially copied from discussion on [StackOverflow](https://stackoverflow.com/questions/9989334/create-nice-column-output-in-python) def main(): # Main Code v_Data = …
