30 Days of Python - Day 3 - Lists & Dictionaries - Python TUTORIAL

Day 3 - Lists & Dictionaries

In 30 Days of Python, I'll teach you the fundamentals of Python. We created this series as an introduction to programming with Python.

Why Python? It's a very popular way to writing computer programs and automations with board applications: SpaceX & NASA use it to launch rockets, Tesla with autonomous driving, Instagram as a web app backend, Intel to pilot drones/UAVs, and many many others.

What you can do with Python is nearly endless:

Run powerful web applications
Fly drones and launch rockets
Run autonomous robots like drones and self-driving cars
Build connected systems with Arduino and Raspberry PI
Automate business intelligences and perform financial analysis
Machine learning including deep learning
And many more ways
That list is fancy but don't let it scare you. Python is just a tool for writing a series of step-by-step automation rules and that's exactly what software is: a collection of rules for a computer to follow.

The right tools in the right hands can impact the world in such amazing ways.

Shakespeare had very few tools for writing plays and yet he continues to influence our entertainment despite being long gone. Creativity mixed with the right tools can transform how we do everything or why we do it.

That's why I want to teach you this tool. The world needs your creatively, your perspective, your project.

Let's do this!

why no tuples?.. and how dictionaries and lists are mutable vs other data types that are immutable (strings, tuples, etc..) VERY IMPORTANT info imo

You got either a talent or a huge skill explaining everything that a newbie wants to know. Tried several courses out there. And yours really make me understand things instead of trying to just remember them.

I am so glad that I found these series. It's so simple and easy to understand. I have already started loving coding and watch most of these videos during my free time. It's like a new hobby for me 😉 kudos guys 👍

Think of the index as "telephone poles" before the list elements. E.g. 1, 2, 3, 4 could look like -- all made up -- 1|2|3|4 . Well, how many telephone poles are before the 1? None, so the index is 0. Before the 4? 3, so to get the '4' we use an index of [3]. Telephone poles ALWAYS come before the item, and there are none at the end. Negative indices use this fact, too, e.g. [-1] starts at the end, and goes back one telephone pole. In our example, that would put it just before the '4', so [-1] would give us 4. Very powerful tool, this!

I love your videos, keep going bro. We appreciate the hard work you are doing. Cheers.

I enjoyed this class. It is great start for beginners. you need patience and an ope mind for python. most importantly you don't need to be a genius to be a python programmer. all you need is creativity and communication.

Wonderful! I've been looking for information about listing dict keys without values all over the place. I got all I need and more just from this video. Thank you so much!

[rajeshsahu]

I saw your video for the first time and it's amazing..

[bunbun]

finished your eCommerce course on Udemy earlier this month and looking to learn more about python.
I look forward to the next 27 days :-)

i searched for many tutorial for python, this one is awesome i suggest to my juniors

[bruhhhhh]

for anyone workin on windows who wants to clear easier:
import os
def cls():
os.system('cls')
(use the tab key before that last line)

then just type cls() and hit enter any time u want to clear the screen.

[leftloft]

I did 3 days in 1 because I learned so fast!

[turabaliyev]

this is how you clear screen in powershell--
import os
clear = lambda: os.system("cls")
clear()

[christianh]

Learning a lot more from you than my E-book

[Travis-no]

Recommended by my teacher. Basics before Kali and mtak. Then the fun begins lol

[andydaseal]

I'm learning more from these types of videos than a traditional education. Love it. You're a hero!

[sushruthkopishetty]

awesome explanations I am loving it.

# This is the dictionry
pips = {"Tie":1, "Noah":2, "Ma":3, "rye":4, "Law":5, "shoe":6, "Cow":7, "ivy":8, "Bee":9, "Toe":10}
# Request the user pick a number to the associated Key
Peg = input(“ pick a number from 1-10 ” + pips [ ])
Print(“This is your associated key ” + peg)
#How do you get the associated user input to the dictionry?

And taking notes not really doing the code due to I don't use the terminal for writing programs as I find it a bit cumbersome to try to build a program in say a discord bot. But it's cool you released it for free most YouTubers lock it behind a paywall (say patreon)

Parabéns, até quem não entende muito bem inglês, compreende sua metodologia de ensino!
