# Learning Plan

## Make a Plan

- [ ] Setup/Create Twitter Account
- [ ] Start 100 Days of Coding Challenge
- [ ] Create a new repo for basic Python exercises
- [ ] Make a commit on Github
- [ ] Tweet that you made your first commit on Twitter
- [ ] Create another Repo for SimpleCalc project
- [ ] Tweet about the project
- [ ] Write a blog post

## Setting a collaborative environment

- [x] Online document where we can share code - HackMD
- [x] Github account to use as the default login
- [ ] Define how to use this document
- [ ] Define syllabus

## How to use this document

1. When starting a new tutorial, write out the topic name here and a link to the source if possible.

# Basics

## Get Python installed

Get Python installed - Automate the Boring stuff with python - Udemy

1. Installed Python (verison 3)
2. Started Idle
3. Understood how interactive shells work

## Calculations

Adding, subtracting

Expression = values + operators

## Data types
Whole number = Integers (int)
Decimals = Floating points (flot)
Texts = String concatenation (string)
Strings beings and ends with ''
An instruction that evaluates to a single value is an expression. An instruction that doesn't is a statement.
#comment - python ignores statements that start with # - useful to write notes/reminders to yourself

## Variables
Values can be stored in variables
Assignment Statement ex. Rashmi = me
Variables can also be used in expressions ex me + 1

## Example of a program

#This program says hello and asks for my name and age
print('Hello World') 
#ask for their name
print('What is your name?')
myName=input()
print('It is nice to meet you, ' + myName)
print('The lenght of your name is: ')
print(len(myName))
#ask for age
print('What is your age?')
myAge = input()
print('Your age will be ' + str(int(myAge) + 1) + ' in a year')

## Types of Data

Boolean Values - True or false

## Check your understanding

Here's stuff we will go through together today.

- [ ] What's a variable? :)

# Exercises

## Write a program to calulcate the average of 3 numbers

### Description

Your program accepts 3 numbers, calculates the average and prints it out as `The average is X`

### To Dos

- [ ] We ask the user through the commandline prompt for input 1,2,3
- [ ] Execute the formula to calculate average
- [ ] Print the solution

### Implementation

Testcases:
- [x] Calculate average of 2, 3, 4, print `The average of the three numbers is 3`
- [x] Calculate average of 22, 400, 168, print `The average of the three numbers is 196.666`

print('Let us calculate the average of three numbers')
print('What is the first number?')
numberOne = input()
print('What is the Second number?')
numberTwo = input()
print('What is the Third number?')
numberThree = input()
print('The average of the three numbers is:')
sum = int(numberOne) + int(numberTwo) + int(numberThree)
average = sum/3
print(average)

## Write a program calculate the average of any given numbers until the user wants to stop

https://replit.com/@larrydalmeida/RedFairDiskdrive

### Description

Your program accepts any number of input numbers from the user, calculates the average and prints it out as `The average of [A,B,C...] is Y`

### Testcases:
- [ ] Calculate average of 2, 3, 4, print `The average of the three numbers is 3`
- [ ] Calculate average of 22, 400, 168, print `The average of the three numbers is 196.666`
- [ ] Calculate average of 2, 3, 4, 5 print `The average of the three numbers is 3.5`
- [ ] Calculate average of 24, 28, 22, 400, 168, 80 print `The average of the three numbers is 120.333`

### Milestones

- [ ] Draw a flowchart of the problem on a piece of paper and upload the picture here
- [ ] Write the program

### Implementation

print('Enter a number, type STOP when done to calculate average')
for index in range(10):
    print(index)

### Work Packages

- [ ] Print message to inform user "Enter a number or type stop when done"
- [ ] HMW move forward with a while loop
- [ ] HMW reduce the number of repitions
