Intro to Flask

Yuri Reimers — Mon, 15 Apr 2024 13:23:17 +0000

Today, we will be diving into Flask concepts and best practices.

First we must import SQLAlchemy. from flask_sqlalchemy import SQLAlchemy

class Employee(db.Model):
tablename = 'soccer_positions'

id = db.Column(db.Integer, primary_key=True)
position1 = db.Column(db.String)
position2 = db.Column(db.String)
position3 = db.Column(db.String)

When we are creating a table. We always start with an id to keep track of our table columns.As listed above, we use the id.Integer to show that our id can only be a number/integer and not a text. The next line, we give the variable a name and use db.Column. Could you guess what does the db.Column is for. If you guessed that we use this to create another column in the soccer_positions table, you are correct. Just like db.Integer, we use db.String to make sure that our column can only be a string. Take some time and get some practice with the basics. Next we will talk about relationships between tables.

Python fundamentals

For me, when I started my coding journey. I started with javascript for 6 weeks and then I started to learn python. Although, I felt more confident in my coding ability and learning how the computer reads code, I found it a bit tricky to learn the new syntaxes of Python. Below I have some examples of the basic of Python.

list: candy = ['Sour Patch', 'Skittles', 'Starburst']
tuple: candy = ('Sour Patch', 'Skittles', 'Starburst')
set: candy = {'Sour Patch', 'Skittles', 'Starburst'}

As you can see, my variable name is candy and I have shown you the different syntaxes between 3 data structures. Make sure that the names inside how '' or "". Making quotations will make sure that it is shown as a string so python can read the code.

Be sure to experiment in your python shell to test out the different data structures. You can use the type function to get comfortable with the different rules of each data_structure.

type(candy = ['Sour Patch', 'Skittles', 'Starburst'])

Intro to React

Now that we have learned the fundamentals of javascript, it's time to learn how to rewrite our code in React. The basics of React is that what we would call a function is now called a component. Components names are capitalized. In React, we write code a lot simpler and create our elements from html all in react. With our components, when we hear the term render or rendering. It usually refers to us returning some code. Below, we have an example of what the difference of vanilla javascript and React is
Javascript -
function basicOf(){
const tool = document.createElement('div')
}
React
function BasicOf(){
return(

My code.
}

You can see that in React. You can use the div tag as if it was an html file.

Intro to Software Engineering

I know what we all are thinking, coding is impossible, it doesn't make sense, how can someone like me learn something as difficult as coding. I had the same thoughts that we all have. I recently started learning javascript and I am surprised at how much I have learned. I am no different than anyone else.
As a beginner guide to get more comfortable with coding fundamentals, we should all ask ourselves the basic questions:

How do we declare a variable? We use 3 keywords that lets the program know that these are variables. We then give our variable a name followed by the equal sign.
const name1 =
let name2 =
var name3 =
How do we assign a value to that variable?

Our value comes after the equal sign. We can have a number or a string as a value

What is a string?

Are words/letters that are between quotation marks
"My name"
'your name'

If you put all of these together. You can get a variable with a value. For example:

const variableName = 'Mike'

'Mike' is the value of variableNames. So every time you write the variableNames. The value will return of 'Mike'.

const variableName = 'Mike'
console.log(variableName)

The console should return Mike

If you practice the basic fundamentals of javascript. You will start to get more comfortable with the basics of coding.
