Python Number Radians() Method

Description

The radians() method in Python number converts angle x from degrees to the radians. The radians() method in Python Number shall be a number or any valid numerical expression. In case the number argument happens to be a positive or negative number, then the Python radians function shall return the output else it returns TypeError.

Syntax

Here is the syntax for radians() method:

radians(x)

Note - One cannot access this function directly, so it is required to import the math module in Python, and then we are supposed to call this function making use of the math static object.

Parameters

• x - This should be a numeric value.

Return Value

This method in the Python math module returns the radian value of an angle.

Example

The example below shows the usage of the radians() method.

#!/usr/bin/python
import math

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

When the above program is run, it produces the following result:

radians(3) :  0.0523598775598
radians(-3) :  -0.0523598775598
radians(0) :  0.0
radians(math.pi) :  0.0548311355616
radians(math.pi/2) :  0.0274155677808
radians(math.pi/4) :  0.0137077838904
