Problem : Polar Coordinates Hackerrank Solution Python

A polar Coordinate (r,θ)

is completely determined by modulus r and phase angle θ.

If we convert complex number z to its polar coordinate, we find:

r: Distance from  to origin 

θ: Counter clockwise angle measured from the positive x-axis to the line segment that joins z to the origin.

Python's cmath module provides access to the mathematical functions for complex numbers.

This tool returns the phase of complex number z(also known as the argument of z).

>>> phase(complex(-1.0, 0.0))

3.1415926535897931

abs

This tool returns the modulus (absolute value) of complex number z.

>>> abs(complex(-1.0, 0.0))

1.0

Task

You are given a complex z. Your task is to convert it to polar coordinates.

Input Format

A single line containing the complex number z. Note: complex() function can be used in python to convert the input as a complex number.

Constraints

Given number is a valid complex number

Output Format

Output two lines:

The first line should contain the value of r.

The second line should contain the value of θ.

Sample Input

1+2j

Sample Output

2.23606797749979

1.1071487177940904

Note: The output should be correct up to 3 decimal places.

Solution

import cmath

b=cmath.polar(complex(input()))

for i in b:

    print(i)
