Today, we're going to learn how to deal with data from forms in Flask.


👉 To start, I've added yesterday's HTML code for my form in main.py for you already. (You're welcome!) Go take a look!


👉 However, at the moment, the app.route() has no method associated with it, so I need to create a route for this page to receive the data.


First, I need a new import: request.


Then I create the app.route - I also need to add an extra argument to specify the methods being received. At the moment, that's just 'post', but it does need to be ALL CAPS - POST.


Finally I define the process() subroutine that returns request.form


👉 Here's the new code on its own:


from Flask import Flask, request

app.route('/process', methods=["POST"])

def process():

  return request.form



👉 And here it is as part of the whole code:


from flask import Flask, request

app = Flask(__name__)

app.route("/process", methods=["POST"])

def process():

  return request.form

  

@app.route('/')

def index():

  page = """<form method = "post" action="/process">

    <p>Name: <input type="text" name="username" required> </p>

    <p>Email: <input type="Email" name="email"> </p>

    <p>Website: <input type="url" name="website"> </p>

    <p>Age: <input type="number" name="age"> </p>

    <input type="hidden" name="userID" value="232"> </p>

    <p>

      Fave Baldy: 

      <select name="baldies">

        <option>David</option>

        <option>Jean Luc Picard</option>

        <option>Yul Brynner</option>

      </select>

    </p>

    <button type="submit">Save Data</button>

  </form>

    

    

    """

  return page

app.run(host='0.0.0.0', port=81)



This will get us the data from the form in a dictionary format, like this:

FOR LOOP , RANGE

  FOR LOOP  A  while  loop is perfect to use when we  don't  know how many times we want the loop to repeat.  If we have an idea of how many times we want the loop to repeat, we can use a  for  loop to loop code in exactly the same way the  while  loop did.  EXAMPLE :  for counter in range(10):   print(counter) RANGE  The  range  function creates a list of numbers in the range you create. If you only give it one number, it will start at  0  and move to a state where the final number is  one less  than the number in the brackets. In this case, the final number would be  9 .  EXAMPLE :  total = 0 for number in range(100) :   total += number   print(total)

ALL ABOUT WHILE LOOP

 WHILE LOOP  A  while  loop allows your code to repeat itself based on a condition you set.   EXAMPLE : counter = 0 while counter < 10:   print(counter)   counter +=1 Infinite Loop  You have to be  really  careful that you don't accidentally invoke an infinite loop! This is where the computer will loop code until the end of time. Without a break. Forever.  This is just saying "count to 10 by 1 each time." to make the loop end. Don't forget, if your  condition  is a  >  then you might need to  -= . This will subtract from the variable instead of adding to it.   EXAMPLE : counter = 0 while counter < 10:   print(counter)    counter += 1

IF AND ELSE STATEMENT

  If Statements    These statements are a bit like asking a question. You are telling the computer:  if  something is true,  then  do this specific block of code. Double equals ( == ) is asking the computer to compare if these two things are  exactly  the same.  EXAMPLE :  myName = input("What's your name?: ") if myName == "David":  What is else? IF  the condition is  not  met with the  if  statement, then we want the computer to do the  else  part instead. Likewise, if the condition  is  met in the  if  statement, then the  else  bit is ignored by the computer. The  else  statement must be the first thing  unindented  after the  if  statement and in line with it    EXAMPLE :  myName = input("What's your name?: ") if myName == "David":  print("Welcome Dude!")  print("You're just the baldest dude I've ever seen...
