Python pyproj convert ecef to lla

Question

I want to convert x/y/z-ECEF positions to lla (lat/lon/alt) using WGS84 in python with pyproj but it seems like the conversion fails.

Example code is here:

Answer 1

lon, lat, alt = pyproj.transform(ecef, lla, x, y, z, radians=True)

Should be :

lat, lon, alt = pyproj.transform(ecef, lla, x, y, z, radians=True)

Since lla = pyproj.Proj(proj='latlong', ellps='WGS84', datum='WGS84') specify the latlong order
