In Python 4j is the literal syntax to create an imaginary number (0 +
4*I). You need to use 4*j.
I don't understand this because Thomas Lignon imported sqrt from sympy,
so why didn't he get the imaginary answer he was expecting?
Indeed, trying this with Python 3.7 and SymPy 1.7, I get:
import sympy
from sympy import sqrt
sqrt(-1)
