Python program to calculate square of a given number
Square is the defined as the multiplication of the number by itself. The square of a number n is given as n2. Mathematically we can implement square of the number as follows. $\mathrm{n^{2}=n*n}$ In the same way we can calculate the square of a given number by using python language too. There are few approaches in python to find the square of a number, let’s see them one by one. Using exponential operator (**) The exponential operator is the operator which is used to perform the exponent arithmetic operation. It is denoted with the symbol **. Syntax The ...
Read MorePython program to calculate Date, Month and Year from Seconds
Generally, time is given in hours or minutes or seconds and from the given seconds, we can calculate the number of days, months and years. There are different modules and functions available in python such as datetime, time and divmod() which helps us to calculate the date month and year from seconds. Using Datatime module Datetime module offers classes to manipulate the dates and times. This module provides various functions and methods such as date, time, datetime, timedelta, minyear, maxyear, UTC etc. In the datetime method of datetime module we have the function utcfromtimestamp() which takes the seconds as ...
Read MorePython program to calculate age in year
Generally, the age of a person is calculated by subtracting the birth year with the current year then the age of the person will be generated in years. In the same way we can calculate the age of a person by using the python modules datetime, dateutil and timedelta. General Calculation of Age in years Current year - Birth year Example In this example we are implementing the general way of calculating the age using pythn language by passing the current year and birth years as the inputs to created function age_calculator() then the total age will be generated ...
Read MorePython program to calculate acceleration, final velocity, initial velocity and time
Acceleration, final velocity, initial velocity and time are the terms related to physical science which are widely used to study the motion and mechanics. Let’s see each one in detail. Acceleration Acceleration is the rate at which an object changes its velocity over the given time. It is denoted by a. Mathematically it is defined as the change in velocity divided by the change in time, the following is the formula. The unit of acceleration is meters per second $\mathrm{(m/s^2)}$ $\mathrm{a \:=\:(\Delta;\:vf − \Delta;vi)/\Delta;t}$ Where, $\mathrm{\Delta\:vi}$ is the Initial velocity $\mathrm{\Delta\:vf}$ is the Final velocity $\mathrm{\Delta\:t}$ is the ...
Read MoreProfiling in Python
In Python profiling is the measure of performance of different parts of a program to check and identify the areas of optimization and bottlenecks. We have many tools to perform profiling for the python code which includes built in modules, libraries and IDEs (Integrated development environments). There are different types of profiling of the python code, let’s see them one by one. Using Line profiling Line profiling is the technique used to measure the execution time of each individual line of the program. It helps us to identify which line is taking more execution time and to identify the tight ...
Read MoreProfile Application using Python Flask and MySQL
Flask is one of the web frameworks which provide libraries to build light weight web applications in python. It is a micro framework, developed by Armin Ronacher who runs an international group of python enthusiasts (POCCO). Flask works on WSGI toolkit and jinja2 template engines. For creating the profile application using python flask and MySQL we have to follow the below mentioned steps one by one. Step − 1 Install the virtual environment by executing the below mentioned command in the command prompt. pip install virtualenv Once the virtual environment is created we can create the new virtual environment into ...
Read MorePriority Queue using Queue and Heapdict module in Python
The priority Queue is the abstract data type which is similar to the queue or stack, in which each element is attached with a priority. Here the priority determines the order of the elements to be dequeued from the queue and the higher priority elements are dequeued before the elements with the lower priority. The priority queues will be implemented using different data structures such as heaps, arrays or balanced trees. The most commonly used implementation is the heap, which is the binary tree based data structure having the value of each node greater than or equal to the values ...
Read MoreShow Normal Inverse Gaussian Distribution in Statistics using Python
In this article we will be discussing the Normal inverse Gaussian distribution and also discuss how to implement and show this distribution using Python. Understanding the Problem The Normal Inverse Gaussian distribution in statistics is the probability distribution which can be used in various fields like finance, risk management and statistical analysis. So we will discuss the logic behind this distribution to implement in Python. Logic for The Above Problem The normal-inverse Gaussian distribution (NIG), a continuous probability distribution, is characterized as the normal variance-mean mixture with the inverse Gaussian distribution as the mixing density. To plot and show the ...
Read MoreShow Normal Distribution in Statistics using Python
In the problem statement we are required to show the normal distribution using Python and its libraries. In the tutorial we will discuss what is normal distribution and how it can be plotted using Python. What is Normal Distribution in Statistics? In the statistics, Normal Distribution is a popular probability distribution. It frequently serves as a model for naturally occurring occurrences and it has a bell-shaped curve as its different feature. It is also known as Gaussian distribution. We can create random data points that fit the normal distribution using a random function in Python to display the ND. Following ...
Read MoreShow Non-Central F-Distribution in Statistics using Python
In the given problem we have to show the non-central F-distribution with the help of Python and its libraries. So we will explore what non-central F-distribution is and how to show it using Python. Understanding the Non-Central F-Distribution The Non-Central F-Distribution is a probability distribution in statistics which is basically used for analyzing variance in the given data. It uses the central F-distribution by using the non-centrality parameters which are used to make deviation. The non-central F-distribution used to determine the probability of observing a particular statistics. The figure of this distribution is generated using the degrees of freedom with ...
