Using the Standard Template Library (STL) vector might make your life easier.

Without thinking ... mylist = [0, 3, 6, 8, 8, 5, 2, 0, 7, 1, 9, 5, 0, 7, 7, 4, 2] s = "" n = 1 for ix, k in enumerate(mylist): if ix == n: s += ' ' n += 4 s += str(k) print(s) # 0 …

Just wanted to know if anyone on DaniWeb is using or at least experimenting with Go.

Also notice that the information returned resides in named tuples.

Have you seen any "dark matter" lately? Actually you can only see the "dark matter effect" as it distorts light through gravitation. When two galaxies collide their shape will change, but the shape of the "dark matter effect" will stay the same.

What have you coded so far?

On first glance look at the items with the highest tottime values. Then check the number of calls and the percall time. Remember that function calls are expensive because of the overhead.

You need to study up on your while loops.

I have found plenty of ads that are a lot better then the TV show.

An oldy but goody: Age of Empires II I find it very relaxing, yet challenging.

The Tkinter GUI toolkit's canvas object is very nice for all sorts of drawings and plotting. However, when it comes to saving the image Tkinter limits you to postscript printer files. One solution is to draw the same image in parallel on PIL's image-draw object in memory. This is made …

I usually go for the lightest weight possible.

The problem with Google is that they keep track of who is searching for what. Let's say you are looking for a brand of shoe, soon after you get shoe sales sending you e-mails.

The lack of communication between Microsoft's different departments seems to be obvious. It is my distinct feeling that Microsoft never liked Python, so they put it in Irons. Years ago Microsoft tried to take over Java, this might have been an attempt to take over Python.

Just a wild guess, look into Jython.

Another thing to watch out for is the value of the Enter key. On Windows it is '\r\n' on Linux it is '\n'. I have seen this giving strange skip effects with the Go language.

@snippsat good explanation!

@snippsat, nice solution!

You cannot burn ideas.

A very basic pygame sprite example. Moving a sprite with the arrow keys, could be the start of a great space game.

A note to coding style: In just about all computer languages programmers try not to exceed about 80 characters per line of code. You could add your comments above the code line to help out, otherwise word wrap makes code pretty hard to read and understand. Again, there are a …

Try ... sf = "For {} Root floor: {}, Ceiling: {}" n = 91 print(sf.format(n, math.floor(n**0.5), math.ceil(n**0.5))) n = 161 print(sf.format(n, math.floor(n**0.5), math.ceil(n**0.5)))

@BustACode we just want to help you with your coding style. Python was written for readability, so yes PEP 8 is good to follow.
