degrees(x)

#!/usr/bin/python
import math

print "degrees(3) : ", math.degrees(3)
print "degrees(-3) : ", math.degrees(-3)
print "degrees(0) : ", math.degrees(0)
print "degrees(math.pi) : ", math.degrees(math.pi)
print "degrees(math.pi/2) : ", math.degrees(math.pi/2)
print "degrees(math.pi/4) : ", math.degrees(math.pi/4)

degrees(3) : 171.887338539
degrees(-3) : -171.887338539
degrees(0) : 0.0
degrees(math.pi) : 180.0
degrees(math.pi/2) : 90.0
degrees(math.pi/4) : 45.0
