Python math.radians() method

math.radians() method is a library method of math module, it is used to convert angle value from degree to radians, it accepts a number and returns the angle value in radians.

Note: math.radians() method accepts only numbers, if we provide anything else except the number, it returns error TypeError"TypeError: a float is required".

Syntax of math.radians() method:

    math.radians(x)

Parameter(s): x – is the number in degree to be converted into radians.

Return value: float – it returns a float value that is the angle value in radians.

Example:

    Input:
    x = 10.25

    # function call
    print(math.radians(x))

    Output:
    0.17889624832941878

Python code to demonstrate example of math.radians() method

# Python code to demonstrate example of 
# math.radians() method

# importing math module
import math 

# number in radians
x = 0
print("math.radians(",x,"): ", math.radians(x))

x = 0.25
print("math.radians(",x,"): ", math.radians(x))

x = 10.25
print("math.radians(",x,"): ", math.radians(x))

x = -0.25
print("math.radians(",x,"): ", math.radians(x))

Output

math.radians( 0 ):  0.0
math.radians( 0.25 ):  0.004363323129985824
math.radians( 10.25 ):  0.17889624832941878
math.radians( -0.25 ):  -0.004363323129985824

TypeError example

# Python code to demonstrate example of 
# math.radians() method with exception

# importing math module
import math 

# number in radians
x = "10"
print("math.radians(",x,"): ", math.radians(x))

Output

Traceback (most recent call last):
  File "/home/main.py", line 9, in <module>
    print("math.radians(",x,"): ", math.radians(x))
TypeError: a float is required
