Python Variable, datatypes, Input and Output function and comments

AGENDA

.py is the file extension of python 

1. OUTPUT FUNCTION

2. HOW TO USE VARIABLE

3. INPUT Function

4. COMMENT

//single comment

/*1. Airtime

datatypes in python: int, float, str, bool,


#python program to calculate area of rectangle 

#area = length x width

#lab5

print("You are welcome")

print("Enter your length")

length = float(input())

print("Enter your width")

width = float(input())

area = int(length) * int(width)

print(area)


List Data Structure 

LIST: this is a collection which is ordered, allows changes and duplicates.it can store multiple items in a single variable.it is a built in datatype. it uses square brackets.

#empty list syntax 

variableName = []

For example, declare and initialize an empty list variable called score

score = []

# to display index

variableName[indexValue]

"""

# python list to store and display some data

color = ["yellow", "black", "purple"]

cgpa = [3.2, 3.99, 4]

score = [1, 40, 39]

print(color)

print(cgpa)

print(score)

# python list to select a particular element

cgpa = [3.2, 3.99, 4]

print(cgpa[2])

"""

# python program to emulate ANN (Artificial Neural Network) using single input, single weight, single bias

inp = [3.2, 3.99, 4]

wgt = [-0.7, 2.4, 5.9]

b = 2

#formula of ANN calculation

#output = (sum(inputs*weights))+bias

out_data = (inp[0]*wgt[0] + inp[1]*wgt[1] + inp[2]*wgt[2]) + b

Objective: -learn how to set up browser and editor for coding (to view window on both sides, let first window be active, hold down window key + right or left arrow) -learn the basic structure of html -learn structure of project files -learn tags like h1-h6, p, a, img, ul, ol, hr, br -learn css selectors class (dot), id (hash symbol) NB: At least, one of your project files must have index.html -to go on multiple pages, create the file name for index.html, services.html, about.html, contact.html -paste the same code of index.html into other files, then edit the content you want it to have Basic structure of HTML < !DOCTYPE  html > < html > < head > < title > Page Title < /title > < /head > < body > < h1 > My First Heading < /h1 > < p > My first paragraph. < /p > < /body > < /html >  <html>     <head> <title> Intro to Web Design</title> <!--<link rel="stylesheet" ...

   DATA STRUCTURE WITH C++ PROGRAMMING USING STACK PREREQUISITES TO IMPLEMENTING STACK IN C++ We will need to understand how to use some of the constructs in C++ that makes up the implementation of stack in C++ against. And this concepts will also help you in developing other codes and to debug or understand the C++ codes in a company's code bank or to interpret a boiler plate code (a ready made code). Some of these constructs or concepts are: 1. sizeof() 2. Function 3. Pointer 4. Function Pointer 5. Arrow operator 6. malloc() 7. typedef 8. struct PHASE 1: sizeof() It is used to determine the size of variables used in a program, it can determine the size of primitive (or predefined) datatype too and for any user-defined datatypes. It is an inbuilt keyword and a compile-time operator. syntax-1 using variable sizeof(variableName); syntax-2 using primitive datatype sizeof(datatype); //code implementation #include<iostream> using namespace std; int main(){ //declare v...

 CGPA CALCULATOR & BASIC HTML WEB DEV PROJECT Introduction: In this cgpa calculator, user will enter the gp for each semester, then click on the submit button to see the cgpa user can also click the reset button to begin a new input for calculation In this mini project we will be using HTML CSS JAVASCRIPT to develop a cgpa calculator NB:   With a querySelector statement, you can select an element based on a CSS selector. This means you can select elements by ID, class, or any other type of selector. Using the getElementById method, you can only select an element by its ID. Generally, you should opt for the selector that most clearly gets the job done. PHASE 1a:  PROTOTYPE (final product) PHASE 1b:  PROTOTYPE (rought sketch) Let's sketch with our hand how the cgpa calculator will look like PHASE 2: Html (for structuring the webpage content) Shortcut for div and class for css: type dot followed by the name you want e.g .cgpatitle Shortcut for div and id f...
