I also added a "if x==1, Z=(1,0)" You can check if $n$ is integer with $\text{n.is_integer()}$. It works even if $n$ is a float. For a complex number $c=\text{complex(a,b)}$ you can check: $\text{c.real.is_integer() and c.imag == 0}$ Unless your calculation is unstable for small values of $\text{c.imag}$, then may be convenient to check $\text{isclose(c.imag, 0)}$ $\text{isclose()}$ belongs to $math$ module from which you imported everything, and allows to set the relative tolerance. « Next Oldest | Next Newest »
