I've got some XYZ coordinates in Kilometers (gotten using wgs) with the origin at the center of the Earth, is it possible to convert this into latitude and longitude?
In addition: how can I do this quickly inside python?
It's simply a reverse of this question here: Converting from longitude\latitude to Cartesian coordinates
This is how you do it. Taking into account both radiuses. Based on: https://gist.github.com/govert/1b373696c9a27ff4c72a and verifyed.

sin_q = math.sin(q)
cos_q = math.cos(q)
sin_q_3 = sin_q * sin_q * sin_q
cos_q_3 = cos_q * cos_q * cos_q
phi = math.atan2((z + eps * b * sin_q_3), (p - e_sq * a * cos_q_3))
lam = math.atan2(y, x)
v = a / math.sqrt(1.0 - e_sq * math.sin(phi) * math.sin(phi))
h = (p / math.cos(phi)) - v
lat = math.degrees(phi)
lon = math.degrees(lam)
print(lat,lon,h)
