You have to apply the scrollbar to a particular widget, for example ...

About 1 billion Valentine’s Day cards are exchanged each year. This makes it the second largest seasonal card sending time of the year

Bright colors, water balloons, lavish gujiyas and melodious songs are the ingredients of perfect Holi. Wish you a very happy and wonderful Holi too. On an unrelated side: I wonder if daylight-savings-time is really saving anything.

Your for loop should look like this ... #declares an empty array (list) called rainfall to #which you can append values with the append method rainfall = [] #for loop to loop from 0 to 11 #remember the 1st element of an array is at subscript 0 for index in …

A dictionary in this case would be a list of special names you expect to find. Simply create a text file with each name on its own line that you can read into Python code and form a list or a set (removes any duplicates). You could assume that each …

Make your life easier by creating a list of (average, name) tuples. That list can be sorted as is. Something like this (stick with the default dictionary as you did before) ... import collections as co # assume this is a string read from a file # showing name:score data …

Well I done it! Got bored after the holidays and bought a Raspberry Pi credit card sized computer ($35), the least expensive LED TV and a Logitech wireless Keyboard/Mouse combo. The way I ordered the kit it cost almost twice as much, but it came with a good 2.5A powersupply, …

One way to find the shortest distance between a series of surface (x, y) points is to let Python module itertools find the non-repeating combinations of point pairs. Now you can apply the Pythagoras' theorem to find all the distances and the minimum distance.

You could do this ... def say(msg, optional=""): print(msg) if optional: print(optional) say('hi', 'option') ''' hi option ''' print('-'*12) say('not') ''' not ''' But this is far simpler ... def say(*args): for arg in args: print(arg) say('hi', 'option') ''' hi option ''' print('-'*12) say('not') ''' not '''

Error messages are poor with .kv files. One reason I don't like them. Check your log file.

`self.top_right = ScrolledText(self, text=self.text, width=50, height=15)` the instance you get refers to the Frame object and that does not have a 'text' argument. The line `Frame.__init__(self, parent)` in class ScrolledText makes that the instance self You can test it with `print(self.top_right.config()['class'])`

A simple code example on how to play wave sound files with the Python module PyGame.

Here we use the eval() function as the backbone of a simple calculator. One table is used for the display. A second table holds the buttons for the keypad. The whole thing forms an attractive looking calculator. To test it, simply paste the code into an editor like notepad and …

A simple way to find out a Python module's location on your drive.

The Python manual at https://www.python.org/doc/ contains a tutorial you may play with. Use the IDLE IDE that comes with your Python installation and start typing the code and try it out.

Not sure why you want to do this, but one way is to build a ringbuffer ... import collections def ringbuffer_append(item, dq=collections.deque(maxlen=3)): ''' mimics a ringbuffer of length 3 you can change maxlen to your needs ''' dq.append(item) return list(dq) # testing mylist = ringbuffer_append('red') print(mylist) mylist = ringbuffer_append('green') print(mylist) …

One good tool to see what is going on in strange code is to put in temporary test print()

Ruby skills are not much in demand. My prediction is that Java demand will slowly fizzle and will be replaced by a combination of Python and C++. Python for the speed of development, and C++ for the speed of code and its large libraries. Python and C++ work very well …

Java is very well entrenched in the CS teaching apparatus. It will take a while for this to modernize.

Also, when you see very repetitive code, then a function or a loop comes to mind.

For small projects in Python I use Tkinter quite a bit. Generally I haven't used **tkdocs** for a reference because the information is scatterd amongst so many languages. The Python manual contains Ykinter and is easier to use.
