Introduction to Numpy Library in Python

Introduction to Numpy Library in Python NUMPY - Introduction Introduction     NUMPY stands for Numerical Python. Numpy is one of the libraries for the python programming language. It is used for high level mathematical calculations. It has the large collection of functions for working with the multi-dimensional arrays, matrices, linear algebra, Fourier transform, etc. Installation of Numpy 1. Open the command or terminal on your system. 2. Enter the following command below.      #installation of NUMPY using PIP      pip install numpy       (OR)       #installation of NUMPY using CONDA      conda install numpy 3. Now, NUMPY installed on your system. To verify that use the command below.      #check for version of NUMPY      numpy --version  Tip : Use Anaconda Navigator , it comes with built-in software of JUPYTER NOTEBOOKS and pre-installed packages like Nump...

Calculate Circumference of Circle in Python

Python - Circumference of Circle Calculation

Python - Circumference of Circle Calculation
Python - Circumference of Circle Calculation


Source Code

Aim :

    To calculate the circumference of a circle using formula in python.

Algorithm :

  • Get the required input from the user by using input statement for 'r'(radius of circle).
  • Calculate the circumference of circle using formula (2*3.14*r).
  • Display the result with the help of print statement

Program :

#calculate circumference of circle using formula in python
#r represents radius and get input from user
r = float(input("Enter the radius of a circle : "))

#calculate circumference of circle using formula (2*3.14*r)
Circumference_of_circle = 2*3.14*r

#Display the result using print statement
print("Circumference of circle is", Circumference_of_circle)

Output :

Enter the radius of a circle : 
10
Circumference of circle is 62.800000000000004

Terminal Code :

Python - Circumference of Circle Program
Python - Circumference of Circle Program


Terminal Output :

Python - Circumference of Circle Output
Python - Circumference of Circle Output


Result :

    The output was executed successfully and result was verified.
