Invoking geodetic2aer using the following code:
`import pymap3d as pm
lat1 = 45.977
lon1 = 7.658
h1 = 4531
lat0 = 46.017
lon0 = 7.750
h0 = 1673

a,e,r = pm.geodetic2aer(lat1,lon1,h1,lat0,lon0,h0)
print ("A=%f E=%f R=%f" % (a,e,r))
`
Output
A=238.075833 E=-7134.628771 R=8876.843346

It should be (please don't take int account different floating point precision)
A=238.08 E=18.744 R= 8876.8

Sorry it was late at night...it was my fault it was printing the wrong output because on the test file i have something like that

x,y,z = pm.geodetic2ecef(lat1,lon1,h1,ellipsoid)
a,e,r = pm.geodetic2aer(lat1,lon1,h1,lat0,lon0,h0,ellipsoid)
e,n,u = pm.ecef2enu(x,y,z,lat0,lon0,h0,ellipsoid)

and of course printing e....was the one of ecef2enu....
I'm really sorry for that
