1. Create a flask app that says "G'DAY MATE!" on launch in browser
2. Create an app that renders this result to html, using a Python loop for the countdown:

   ready to takeoff
   10
   9
   8
   7
   6
   5
   4
   3
   2
   1
   blastoff

3. create this pattern in html using Flask and a Python loop. Extension: make this scalable using a var in code:

   *
   * *
   * * *
   * * 
   *

4. define a function processArray() that processes a list of 4 elements and writes them to html in reverse order:

   value: 7
   value: 3
   value: 3
   value: 1

Solutions

blastoff

from flask import *
app = Flask(__name__)

@app.route("/")
def go():
    markup = "ready to takeoff<br>"
    count = 10
    while (count >= 1):
        markup = markup + str(count) + "<br>"
        count = count - 1
    markup = markup + "blastoff"
    return markup

app.run(debug=True)

process array

from flask import *
app = Flask(__name__)

myarray = [1,3,3,7]
markup = ""

@app.route("/")
def go():
    processArray()
    return markup

def processArray():
    global markup
    markup = ""
    for stuff in reversed(myarray):
        markup = markup + "value: " + str(stuff) + "<br>"

app.run(debug=True)
