Hi there,
I've a problem with interact together with a request:
I'd like to write a function which return some interact, for example:
def make_interact(i):
def _(choice=["x%i"%u for u in range(i)]):
print choice
return interact(_)
However, if I write that the various choices are setup vertically. As in
[x0]
choice [x1]
[x2]
I'd rather have them setup horizontally as
choice [x0] [x1] [x2]
which is the case when I write as usual:
@interact
def _(choice=["x%i"%u for u in range(3)]):
print choice
or
def make_interact_correct(i):
def _(choice=["x%i"%u for u in range(i)]):
print choice
return _
interact(make_interact_correct(3))
Note also that I get on the screen
<function _ at 0x4d36a28>
after the interact. Am I doing something wrong or stupid ?
I've another question about interact. I use them to demonstrate some
algorithms during my course. So using yield I have a button [Step] which allow
me to execute the algorithm step by step as in a debugger. At each step I draw
some figure so show the status of the algorithm.
I'd like to have a button [Cont] such that the figure are shown in sequence
but without waiting for me to click on my browser. Is this feature easily
achievable ?
For those who are interested, I'm teaching algorithm and in particular sorts
and here is the code for the insert sort.
Cheers,
Florent
def trace_algo(cmd):
sort_gen = iter(cmd)
def bla(trace=selector(["Step", "Cont"],
buttons=True)):
global dessin
try:
mess, dessin = sort_gen.next()
except StopIteration:
mess = "======== Fin ======="
print mess
dessin.show()
return interact(bla)
def plot_tab(tab):
return sum(point(v, size=40) for v in
enumerate(tab))
def vert(i, tab, color="red"):
return line([(i, 0),(i, max(tab))], color=color)
def horiz(i, tab, color="green"):
return line([(0,i),(len(tab),i)], color=color)
def insert_sort(T):
def dessin():
return ("i=%i, j=%i, e=%i"%(i,j,e),
plot_tab(T)+vert(j, tab)+horiz(e, tab))
yield "Start", plot_tab(T)
for i in range(1,len(T)):
e = T[i]
j = i
yield dessin()
while j>0 and T[j-1] > e:
T[j] = T[j-1]
j -= 1
yield dessin()
T[j] = e
yield dessin()
