I'd say its safe to manually construct static paths. Whenever url components
are specified by the user you should use urllib.quote() or similar to ensure
validity.

+1. It would be good to fix parts of the Sage library which do otherwise.
However, if you want to construct a URL (as in some of the scripts, like

Thats true if the multiple slashes are in the middle (though I agree that
thats the case here).

Posix doesn't define the behaviour of double slashes. Most implementations
treat it as single-slash, which is sane but clearly we shouldn't rely on
benign behaviour. If you need to build a path, you should always use
os.path.join. Not all OS'es understand slash as a path separator.

Yes, but the fact that f(2,3) has a

Let f be a polynomial in two variables x and y over a ring R.
Consider the following three commands
i) f(2,3)
ii) f(x=2,y=3)
iii) f.subs(x=2,y=3)
They give the same results but not the same type. i) gives an element
in R while ii) and iii) are constant polynomials in two variables.

Hello,
I have some questions about semantics and typographics convention in :
1/ Permutation
2/ PermutationGroupElement
3/ permutations (with lower p)
4/ Permutations
Suppose I don't know Sage. How can I imagine the design of each function ?
What is the first (question or) answer I must get ?

If you do have write permissions to that directory (*with* the double
slash), then the double slash may not be the problem.
And that file looks like this -
