Python - calculate arctangent in radians and degrees

We know that the arctangent of 1 is 45 degrees or pi/4 radians. Now, let see how we can calculate the value using python:

Using Numpy:

import numpy
import math
numpy.arctan(1) # calculates in radians
0.78539816339744828
numpy.arctan(1)*180/math.pi # calculates in degrees
45.0

Using regular python:

import math
math.atan(1) # calculates in radians
0.7853981633974483
math.atan(1)*180/math.pi # calculates in degrees
45.0
