Python Math: Calculate the area of a regular polygon

Python Math: Exercise-28 with Solution

Write a python program to calculate the area of a regular polygon.

Sample Solution:-

Python Code:

from math import tan, pi
n_sides = int(input("Input number of sides: "))
s_length = float(input("Input the length of a side: "))
p_area = n_sides * (s_length ** 2) / (4 * tan(pi / n_sides))
print("The area of the polygon is: ",p_area)

Sample Output:

Input number of sides: 4                                                                                      
Input the length of a side: 20                                                                                
The area of the polygon is:  400.00000000000006

Python: Tips of the Day

Getting rid of unwanted characters:

You can get rid of whitespaces or any specific character using strip methods in Python. You can use either plain strip for both sides, lstrip for the left side and rstrip for the right side only.

str="+++Welcome python+++"
str.strip()

print(str)

Output:

+++Welcome python+++
