Python Math: Convert degree to radian

Python Math: Exercise-1 with Solution

Write a Python program to convert degrees to radians.
Note : The radian is the standard unit of angular measure, used in many areas of mathematics. An angle's measurement in radians is numerically equal to the length of a corresponding arc of a unit circle; one radian is just under 57.3 degrees (when the arc length is equal to the radius).

Test Data:
Degree : 15
Expected Result in radians: 0.2619047619047619

Sample Solution-1:

Python Code:

pi=22/7
degree = float(input("Input degrees: "))
radian = degree*(pi/180)
print(radian)

Sample Output:

Input degrees: 90

Sample Solution-2:

Use math.pi and the degrees to radians formula to convert the angle from degrees to radians.

Python Code:

from math import pi
def degrees_to_rads(deg):
  return (deg * pi) / 180.0
print(degrees_to_rads(180))
print(degrees_to_rads(90))

Sample Output:

3.141592653589793
1.5707963267948966
