Re: [Tutor] function error

Re: [Tutor] question about lists and doctest

The doctest module searches for pieces of text that look like interactive Python sessions, and then executes those sessions to verify that they work exactly as shown. Here ur a_list[3] in docstring is 42 then doctest expects it to be 42 for success. Since u changed 42 to 16 then it is not = 42 as p

Re: [Tutor] continuous running of a method

The problem with this while loop is if your random value doesn't lie between the mentioned range then ur 100% cpu would be utilized. The one thing u can do is to sleep for some time lets say 0.5 sec after every while loop iteration , in this case ur cpu utilization will go down. --nitin On Mon, A

Re: [Tutor] Adding all numbers in a file or list

alternatively you can use the lambda , reduce function for summing up all the numbers in a list for e.g:- lis = [1,2,3,4,5] p = reduce(lambda x,y : x+y, lis) p will have the value = 15. --nitin On Mon, Aug 23, 2010 at 9:05 PM, aug dawg wrote: > Oh okay, sorry about that. > > Thanks for the

Re: [Tutor] check the terminal keyword

You can use raw_input like for e.g. u_input = raw_input("user_command") n then u can check u_input against anything. if doesn't matches then u can throw an error. I hope it shall help you. --nitin On Sat, Aug 21, 2010 at 6:37 PM, ANKUR AGGARWAL wrote: > i m making a app in which i launch applic

Re: [Tutor] List comprehension for dicts?

result = [i%2 for i in itertools.takewhile(lamda x:i< 10, seq)] is a good approach but it is taking little more time than the for loop over iterator. def takewhile(predicate, iterable): # takewhile(lambda x: x<5, [1,4,6,4,1]) --> 1 4 for x in iterable: if predicate(x):

bject") class mm(mymut): x = '' y = '' def __init__(self,x,y): self.x = x self.y = y p = mm(10,11) print p.x print p.y I have created this immutable object.Is there any other better implementation? thanks -- nitin On Thu, Aug 19, 201

Re: [Tutor] Getting confusing NameError

use raw_input instead of input . as using input is unsafe as it evaluates your input as python command. for e,g. x = input("enter command") and u entered "1 + 2" as input., then it will evaluate 1+2 = 3 = x. -nitin On Wed, Aug 18, 2010 at 12:45 PM, shane brennan wrote: > Hi Tutors > > This is m

Re: [Tutor] reading from 2 file output to 1

I think in both the while loops , for loops are iterating over the new lines, as a result col1,col2,col3,col4,col5,col6,col7 as a result after both the while loop finishes these colums would only be having the values of the last lines from both the files. as a result the new file3 would only be hav
