[sage-support] Missing 1 required positional argument
The following code doesn't work inside Sage Math Cell. I am getting
message: TypeError: Check() missing 1 required positional argument: 'n' . I
guess I use a selector incorrectly. How can I fix it?
gp.eval("xmat(r,n) = [2*x, -1; 1, 0]*Mod(1,x^r-1)*Mod(1,n);")
gp.eval("smallestr(n)={if(n==1 || n%2==0, return(0));forprime(r = 3,
oo,my(u=n%r);if (u==0 && r < n, return(0));if (u!=0 && u!=1 && u!=r-1,
return(r)));}")
gp.eval("myisprime(n)={my(r = smallestr(n));if (r == 0, return(n ==
2));my(xp = xmat(r,n)^n*[x,1]~);xp[2] == Mod(x*Mod(1,n),x^r-1)^n;}")
def Check(n):
if gp.function_call("myisprime",[n]).sage()==true:
return ("Prime!")
else:
return ("Composite!")
@interact
def _(n=2017,action=selector(['Check'],buttons=True,label='')):
action = eval(action)
print (action())

Re: [sage-support] Mixing GP and @interact inside Sage Cell
Thank you, it works!

[sage-support] Mixing GP and @interact inside Sage Cell
Why the following code doesn't work inside Sage Cell?
gp("""
square(x)=x^2;
""")
@interactdef _(x=2):
print(square(x))
