2014-09-12 11:20:06 +0200	commented answer	List all available classes and functions It is a bit messy to parse; it feels like it should be possible to do from within Sage. In Mathematica, it is quite easy to do this.
2014-09-11 21:04:58 +0200	asked a question	List all available classes and functions How can I get a list of all available classes and the corresponding methods in Sage? The reason I ask is that I would like to create a syntax file for the editor Kate. I have not found one so far, if there is one, this would also solve my issue.

2013-07-06 12:08:12 +0200	marked best answer	Strange behaviour You can try `map(lambda x: x%2,[4,3,2,1,1])` then `sum(map(lambda x: x%2,[4,3,2,1,1]))` will return the desired output. What happens when you use `mod(x,2)` is that `sage` returns an element of $\mathbb{Z}_2$, however the `%` operator returns an `Integer`.

2013-07-05 18:38:03 +0200	asked a question	Strange behaviour I am new to Sage, so please help me understand the following: How come `map(lambda x: mod(x,2),[4,3,2,1,1])` returns the perfectly sane answer [0,1,0,1,1] but trying to compute the sum `sum(map(lambda x: mod(x,2),[4,3,2,1,1]))` gives the value 1, and not 3. Somehow, it seems that sage thinks that I wish to apply the inner lambda again on the result of the sum.
