Determining if a variable is within range?

问题 I need to write a loop that does something like: if i (1..10) do thing 1 elsif i (11..20) do thing 2 elsif i (21..30) do thing 3 etc... But so far have gone down the wrong paths in terms of syntax. 回答1: if i.between?(1, 10) do thing 1 elsif i.between?(11,20) do thing 2 ... 回答2: Use the === operator (or its synonym include? ) if (1..10) === i 回答3: As @Baldu said, use the === operator or use case/when which internally uses === : case i when 1..10 # do thing 1 when 11..20 # do thing 2 when 21.

built-in range or numpy.arange: which is more efficient?

问题 When iterating over a large array with a range expression, should I use Python's built-in range function, or numpy's arange to get the best performance? My reasoning so far: arange probably resorts to a native implementation and might be faster therefore. On the other hand, arange returns a full array, which occupies memory, so there might be an overhead. Python 3's range expression is a generator, which does not hold all the values in memory. 回答1: For large arrays numpy should be the faster

问题 I have an event with start_time and end_time and want to check if the event is "in progress". That would be to check if today's date is in the range between the two dates. How would you do this in a function? 回答1: Use === Actually, there is an operator that will do this. Make a Range and compare Time objects to it using the === operator. start = Time.now.to_i range = start..(start + 2) inside = start + 1 outside = start + 3 # ok, now... range === inside # true range === outside # false Update

regex number range 1-17

由 杀马特。学长 韩版系。学妹 提交于 2019-11-27 08:07:50
问题 Can someone tell me how to match a number between 1-17 with a regex: I tried [1-9]|1[0-7] but it matches 8 in the 18 for example because of the first part. Any ideas? I don't want to have leading zeros. edited: The problem is I'm trying to validate a UK postcode like to start with: KW1-17 (it could be KW1, KW2 up to KW17) ... and this is just the outward part. The postcode may be KW15 1BM or KW151BM so I can't just use anchors to match the whole string ... it becomes more complicated. 回答1:

How to parallelize iteration over a range, using StdLib and Python 3?

由 馋奶兔 提交于 2019-11-27 07:57:39
问题 I've been searching for an answer on this now for days to no avail. I'm probably just not understanding the pieces that are floating around out there and the Python documentation on the multiprocessing module is rather large and not clear to me. Say you have the following for loop: import timeit numbers = [] start = timeit.default_timer() for num in range(100000000): numbers.append(num) end = timeit.default_timer() print('TIME: {} seconds'.format(end - start)) print('SUM:', sum(numbers))

How do I fix the 'Out of range value adjusted for column' error?

由 这一生的挚爱 提交于 2019-11-27 07:36:16
问题 I went into phpMyAdmin and changed the value for an integer(15)field to a 10-digit number, so everything should work fine. I entered the value '4085628851' and I am receiving the following error: Warning: #1264 Out of range value adjusted for column 'phone' at row 1 It then changes the value to '2147483647'. After some googling, I found this article that explains how to fix the problem. http://webomania.wordpress.com/2006/10/01/out-of-range-value-adjusted-for-column-error/, but I don't know

Can I use the HTTP range header to load partial files “on purpose”?

由 我们两清 提交于 2019-11-27 07:08:26
I'm playing around with the HTTP range header ( specs ). From what I understand I can set byte ranges of files ala 0-199/2000 200-499/2000 500-799/2000 etc Question: Say I only want to access certain ranges of a file, would it be possible to specify these ranges and then work with the "incomplete" data I received? I'm playing around with filtering a large log file, so I'm curious if something like this would work. Thanks for inputs! You are right the link which you posted in the comment would be probably the best approche. As your question sounded interesting i tried it out. You probably did

How to set caret/cursor position in a contenteditable div between two divs.

由 江枫思渺然 提交于 2019-11-27 06:20:18
问题 Consider the following contenteditable div. <div contenteditable="true"> <div>bold text</div><div>bold text</div> </div> If I position the cursor between the two divs and start typing the text comes out bold instead of inserting a new text node between the two divs. The same happens if you hit home and try to type something in front of the first div. It becomes part of the first div. If I inspect the startContainer of the range that's returned from the selection, I get the content for one of
