A safer approach would be - with open(, as : //operation with the file. This way, you do not have to remember to close the file explicitly. On Wed, Jan 30, 2013 at 12:27 PM, Dave Angel wrote: > On 01/30/2013 01:51 AM, Gayathri S wrote: > >> Hi All! >> I don't know how to

[Tutor] Query - Where to put in global variables, if needed, as a good programming practice

Hello, The point of good-bad-ness of global variables aside, if I needed to use them, which is a better place to put them. 1. In the __init__ function of a class? So they are available at the time an object is initialized or 2. In the actual function of the class where the variables are needed? Pr

Thanks Jerry! By the way, I know I can change the way the loops works and bypass this issue :) I just wanted to mention this behavior which I thought interesting and present some corner case (I have worked extensively in testing). And I agree, probably I should not have used color. Bad on my part.

[Tutor] Pythonic way of concatenation of elements in an array

Hello, My code is - l = len(m) item = str(m[1]) for i in range(2,l): item = item + "-" + str(m[i]) This code is part of a bigger function. It works fine. But I am not happy with the way I have written it. I think there is a better (Pythonic) way to rewrite it. If anyone knows how to improve

Re: [Tutor] how to remove the coming duplication

Hello, list.remove will remove the first occurrence of the value from the list. So the output is expected as far as Python is concerned. May be you should think about using pop function. Please take a look at the code below >>> def RemoveComingDuplicates(a): for i in range(len(a)-1): print i,i+

Hi, Let me understand the problem - Do you want to count the number of times the application was restarted between today and 7 days back? => If yes, then you will need to do some string manipulation to get the required dates. Then you will need to apply both the conditions to the line i.e. if the

Re: [Tutor] Creating a dictionary

I think the way - d = dict({'one': 1, 'two': 2}) can be used to created dictionary using list comprehension. e.g. >>> d = dict((i,i**2) for i in range(10)) >>> d {0: 0, 1: 1, 2: 4, 3: 9, 4: 16, 5: 25, 6: 36, 7: 49, 8: 64, 9: 81} I do not think the second approach can be used in this fashion. >Fr

Re: [Tutor] Creating a dictionary

The first approach does not really give you any variable (in easy form) to operate upon. The second approach returns a dict object that you can later reuse in easier form. So one advantage is certainly that ease of object reuse and also object modification. If you want to add, remove, update anythi

I don't think we can solve your homework :). But regarding hint, try to think in terms of each number as part of list and then process the list. Also, consider the option if the numbers will be given as a string or as integers or float etc. Thanks. On Wed, May 18, 2011 at 2:49 PM, Cindy Lee wrot
