[sage-devel] Sage 4.4.rc0 released

This release candidate for Sage 4.4 closed 19 tickets (on top of 4.4.alpha1). On trac, these tickets were labeled as "merged into 4.4.alpha2", but then I decided that alpha2 should be the same as rc0. Source tarball: http://sage.math.washington.edu/home/release/sage-4.4.rc0/sage-4.4.rc0.tar sag

[sage-devel] Re: weird bug in mod()

I'm sure I'm not the only one on this list to have made this mistake before... Running a .py file is not the same as typing commands into an interactive session, because Sage doesn't do preprocessing on .py files. There is a way to call the preprocessor directly, but that's not necessary here; ren

[sage-devel] weird bug in mod()

This works fine from the command line (4.4.alpha1): sage: K. = NumberField(x^3 - 7) sage: R. = K[] sage: f = y^2 + 3 sage: g = y^3 - 5 sage: h,alpha,beta = XGCD(f,g) sage: c = 1+((a-1))*alpha*f sage: l = lcm(f,g) sage: c.mod(l) (-3/52*a + 3/52)*y^4 + (5/52*a - 5/52)*y^3 + (15/52*a - 15/52)*y + 27/

[sage-devel] Where to add a section to the tutorial?

Hi! Sage's coercion makes life easier (allowing to do arithmetic without too much fuzz), but is not easy and may give rise to confusion. 1. I find coercion is not properly addressed by the tutorial and the "Sage constructions". Do you agree that a section on coercion should be added (I'd voluntee

[sage-devel] Re: Right format for multiple lines statement in docstring ?

Thank you John for the improvement ! I will for sure change it. But there is still an unanswered question (I must admit I was not very clear). When I add the following string in my docstring 981 sage: for i in range(1,10): 982 sage: for j in range(1,10): 983

Why don't you, instead of collecting all the booleans in a list, assert each one? On 23 April 2010 13:55, ablondin wrote: > Hello, everyone ! > What is the right syntax to include a test like this one in the > docstring ? > Delete this line: > sage: valid = [] Keep this: > sage: for i in rang

[sage-devel] Right format for multiple lines statement in docstring ?

Hello, everyone ! What is the right syntax to include a test like this one in the docstring ? sage: valid = [] sage: for i in range(1,10): sage: for j in range(1,10): sage: if i != j: sage: w = words.KolakoskiWord(alphabet=(i,j)) sage: valid.append(w[:50] == w.d
