How about this: [code] >>> a = [[1,2,3], [4,5,6], [7,8,9]] >>> new_a = [] >>> for each_a in a: ... new_a += each_a ... >>> new_a [1, 2, 3, 4, 5, 6, 7, 8, 9] >>> [/code]

In order to see a hyperlink you would need something that was capable of rendering HTML. Why don't you try opening the output from Python in your web browser

The backslash (\) is used for an "escape character". So \t is the escape character for a tab, \n is for newline, and \" or ' are escapes for a double and single quote respectively. Let's say we have a string: [icode]'Hi my name is Charlie'[/icode]. The single quotes are …

Maybe it's four 8-bit numbers together? [code]>>> i = '100010101001000010000011111001010' >>> first_num = int(i[:8],2) >>> secnd_num = int(i[8:16],2) >>> third_num = int(i[16:24],2) >>> fourt_num = int(i[24:32],2) >>> first_num 138 >>> secnd_num 144 >>> third_num 131 >>> fourt_num 229 >>> [/code]

Are you describing a "race condition"? If you are working with something like this you are not a newbie, this is complex stuff. try googling "data race condition" and learn about the different methods to solve this fundamental software design issue.

You could do a simple while loop: [code]import subprocess repeat = 'y' while repeat == 'y': subprocess.call(["programname"]) repeat = raw_input("Would you like to run again? (y/n) ")[/code]

You have a lot of options. If you're looking to purely look at html you can use urllib2, or if you'd rather have the module parse out all the elements for you and give you purely the text data you'd be better off using beautifulsoup. Search this forum to find …

It looks like you're using a Python version that is not 3.X ... so in that case you should be using raw_input() instead of input(). raw_input stores the user's input as a string, which is the way input() works in Python 3.0 and up

This would also likely require that your Python program run in the background as a service. It would need to monitor the presence of a USB flash drive and act accordingly when it detected one. There is information in this forum for setting up a service in Windows if you …

Here, [URL="http://www.python.org/dev/peps/pep-0263/"]this should give you some insight[/URL] into how to define an encoding style for your whole python script.

You can use either a tk or wxPython file dialog. Both should provide a native file chooser window for the user. Plenty of examples on this site or through searching google.

So you literally take your object and perform a [icode]str(object)[/icode]? And that's what you're trying to turn back into a proper python object? For that you would use a simple eval(): [code]to = ['This is my list', 'With Stuff', [0,1,2,3,4], 'Foo', 112, 5, '57 + 1'] my_saved_ver = str(to) tr …

What about passing the class instance as a parameter to your function?

Typically when you create a module that you want to use in another script you save it as a file (we'll use my_module.py as an example). Then in your script in which you want to use said module you would do [icode]import my_module[/icode]; however this assumes that my_module is visible …

Using a leading double underscore on a class member makes it psuedo-private; however with persistence you can still see/access the object (it's just not immediately apparent). There is no such thing as "private" in Python. [code=python]>>> class A(object): ... _Member_A = 'a' ... __Member_B = 'b' ... >>> dir(A) ['_A__Member_B', …

Yes, you could create a general Student class and then go about creating instances of the class. Each instance would represent a different student and would contain the necessary data to individualize and represent the student's details.
