python 弧度与角度互转

import math
def deal(yaw):
        if(yaw<0):
                print(-(abs(yaw)/math.pi)*180)
                print(math.degrees(yaw))
        else:
                print((abs(yaw)/math.pi)*180)
                print(math.degrees(yaw))

yaw=math.pi/6
deal(yaw)
yaw=-math.pi/3
deal(yaw)
