Introduction To Python
Python is a widely-used, interpreted, object-oriented, and high-level programming language with dynamic semantics, used for general-purpose programming. It was created by Guido van Rossum, and first released on February 20, 1991.
Python is a computer programming language often used to build websites and software, automate tasks, and conduct data analysis. It is also used to create various machine learning algorithm, and helps in Artificial Intelligence. Python is a general purpose language, meaning it can be used to create a variety of different programs and isn’t specialized for any specific problems. This versatility, along with its beginner-friendliness, has made it one of the most-used programming languages today. A survey conducted by industry analyst firm RedMonk found that it was the most popular programming language among developers in 2020.

Polar Coordinates in Python – HackerRank Solution
Problem:
Polar coordinates are an alternative way of representing Cartesian coordinates or Complex Numbers.
A complex number z
is completely determined by its real part x and imaginary part y.
Here, j is the imaginary unit.
A polar coordinate (r, q)is completely determined by modulus r and phase angle q.
if we convert complex number z to its polar coordinate, we find:r : Distance from z to origin, i.e., √(x^2+y^2)
q : 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.
cmath.phaseThis tool returns the phase of complex number z(also known as the argument of z).
>>> phase(complex(-1.0, 0.0)) 3.1415926535897931
absThis 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 q.
Sample Input :
1+2j
Sample Output :
2.23606797749979 1.1071487177940904
