This does take time, interestingly when the numbers are symbolic:
{{{
sage: f=range(6)
sage: %time Tuples(f,1);
CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s
Wall time: 0.00
sage: u=[CC(CC.random_element(10)+i) for _ in range(5)]
sage: %time Tuples(u,1);
CPU times: user 0.48 s, sys: 0.22 s, total: 0.70 s
Wall time: 7.12
}}}
So I'm guessing you're using symbolic numbers instead of complex
numbers. It's easy to get them wrong:
{{{
sage: symbol=2+I ; type(symbol)
<class 'sage.calculus.calculus.SymbolicArithmetic'>
sage: a=CC(2+I) ; type(a)
<type 'sage.rings.complex_number.ComplexNumber'>
}}}
Hope that helps
