[sage-support] Integer comparison with string question
python: 1 < 'haha'
true
sage: 1 < 'haha'
false
Ok, python and sage do something different. Why?
sage: preparse('1 < "haha"')
'Integer(1) < "haha"
And here I am stuck. I have looked through the sage reference manual, and tried
googling, but no luck.
Would a kind person explain why python and sage give different answers?
Mariah

[sage-support] notebook question - "Output truncated"
I have a sage script that generates some graphs and text. When I load the script in a cell of a sage worksheet, I get everything I expect ... plus a message "WARNING: Output truncated" and a link for "full_output.txt". If I "save & quit" the worksheet, then restart the worksheet, now I do NOT see all the text associated with some of my later graphs. I am using sage-4.1. Is there a way to enlarge the size of my worksheet cell so that all my data is saved (and thus not truncated)? -- Mariah --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org -~--~~~~--~~--~--~---

[sage-support] Re: How run file code in Sage notebook?
When I paste into my Sage notebook cell load "/path/to/my/script.sage" and then click "evaluate", I get no output. All that happens is that a new cell comes up. The same thing happens when I use "attach" instead of "load". Yet if I paste the code in "/path/to/my/script.sage" into my Sage notebook cell and then click "Evaluate", then I get the plot that I expect. Have I hit another Sage bug? I am on a networked file system if that makes difference.

[sage-support] How run file code in Sage notebook?
I have some Sage code that plots a graph. When I paste this code into a cell of a Sage notebook and evaluate the cell, I get the graph I expect. Now instead of pasting the code into the cell, I want to somehow tell the Sage notebook to execute the Sage code that exists in a file. Is this possible? If so, I am not having any luck figuring how to do it from the Sage reference manual, or any of the tutorials on the Sage Help web page. Would a kind Sage guru please give me a hint?

Minh, > Tutorials, tips and techniques on making and managing patches should > go in the Developers' Guide at > > http://www.sagemath.org/doc/developer/ Aha! This already has the stuff I was going to write up. The reason that I never looked at this is that I do not consider myself a "developer". I found the Sage documentation for sxrange/xsrange confusing, William suggested I write a patch for the documentation, and I tried to do so. The section that you referenced "Producing Patches with Mercurial" is in the second half of the Developers' Guide. I never would have found it without your pointing me at it. I respectfully suggest that this section be split out to a "How to make a Sage patch (for newbies)" ... or at the very least moved to the beginning of the Developers' Guide.

Actually, I am not. I just followed the directions that Minh gave. Is there a "How to make a Sage patch (for newbies)" page anywhere? If not, there should be.

[sage-support] sxrange / xsrange possible bug
Perhaps I do not understand sxrange / xsrange correctly. The reference manual entries for them seem to be similar. Is there a difference? (If one is just an alias for the other, it would be best to say so. If they are different, the reference manual needs to emphasize the difference.) Also the reference manual entry for sage.misc.misc.sxrange has the note : This function is called xsrange to distinguish it from the builtin Python xrange command. Should it say "sxrange" rather than "xsrange"? Finally here is my attempt to use sxrange (xsrange gives similar output): e = 1 while true: print Integer(10^e) for i in sxrange(Integer(2),Integer(10^e)): if i == 3: break e += 1 gives 10 100 1000 1 10 100 1000 1 10 100 1000 1 10 100 1000 1 10 100 1000 Traceback (most recent call last): File "zzzbug.py", line 7, in for i in sxrange(Integer(_sage_const_2 ),Integer(_sage_const_10 **e)): File "/home/mariah/sage/sage-4.1.1-x86_64-Linux-core2-fc/local/lib/python2.6/site-packages/sage/misc/misc.py", line 1059, in generic_xsrange for k in xrange(icount): OverflowError: long int too large to convert to int I really want an iterator for the "for i in ..." loop.
