How to convert Radians to Degrees and Degrees to Radians in Python

Convert Radians to Degrees and Degrees to Radians  in Python


In this blog we will learn how to convert the python degrees to radians and python radians to degrees

By convention every value you input in trigonometry functions in python will give output as radians to convert it into degrees 


Code Convert Radians to Degrees :


import numpy as np
import matplotlib.pyplot as plt
t = np.linspace(0,360,360)
x = np.sin(np.radians(t))  #just type np.radians before defining input trignometry function variable 
plt.plot(t,x)



What if i don't write np.radians 
Then python will give output in  radians as shown in code below

import numpy as np
import matplotlib.pyplot as plt
t = np.linspace(0,360,360)
x = np.sin((t))
plt.plot(t,x)


What if my values are in degrees but want to convert it into radians ?
import numpy as np
import matplotlib.pyplot as plt

x = np.sin(np.radians(45))  # value convert from radians to degrees 
y = np.sin(np.degrees(x))  # value convert from degrees to radians in python
print(x)

Note :
  • writing np.radians /np.degrees  to convert the value in degrees/radians respectively look odd but this is the syntax or if you don't like it you can make your own function
