Hello,
is this not from math ?
nums = IN[0]
prims = []
for i in nums:
prims.append(isprime(i))
Actually a lot more functions… how do i access them?
prime(n)
primefactors(z)
primepi(n)
sieve.primerange(n1,n2)
Where are you getting those functions? If you didn’t see them coming from the math library then they probably came from somewhere else. I’ve never seen those functions before.
They are from the sympy module, which you would need to load to be able to use.
Whoops! Wrong code… thanks @timhevel
Some code to that properly finds prime numbers in a list.

I am “just” architect, f.e. what does “congruent” mean… the book is realy explaning basics. I understand a little pit better how data got processed. I can better follow and understand warnings and errors.
Google “congruent” (Tip)

Are these libraries loadable? like SymPy ?
is this similar issue like IronPython and Python3?
is there an instruction anywhere to get them and load them to the correct path on my Computer?
