Python Dictionary Tip!! #python #coding #programming

Thank you!!

This is helpful as there are examples 🎉

Is there a way to do this in c#

In Java we extend the class and implement extra method get with conditional to check if key exists and return default value if not. In python you just have it implemented already.

Good short

Like NVL()

Better practise to my knowledge would be having a Players class that wraps all the relevant information, and then just a list of classes.
Another option would also be importing defaultdict.

Love it

what theme do you use

Orrrrrrrr every player gets a default value assigned cause you normally cant afford having a messy database

Lol, lose with the word database. A list of variable names that are dicts.

Im pretty sure its called get or default

When would you ever use dic[key] over dic.get(key)

This is amazing for getting values in fetch request and accounting for empty values. In the pokemon api there are some pokemon that have many types and I was unable to render both types since I would get an error if the second type value was empty now I can assign it an empty string

Python developers have discovered dictionary functions
Phenomenal

Hello don't understand this...

Couldnt you just make the line p['level'] or 0? Does .get() do something special?

The future of coding is here. Every time u type code a meme pop out.

Or simply do if 'level' in p.keys()

Entendi tudo

Good stuff

Wwoooo

Working with non strict data types. Tisk tisk

please more videos abouts pandas and hoe its work full video start to ends please brooooo

Hey, @b001 can you make a video on how to setup vs code for python?

Can't python ignore KeyError if you use 'or' keyword?

Is this work in Python?:
level = player['level'] or 0

Becuse you can do this in php with nullsafe (??):
$level = $player['level'] ?? 0;

Or JS with 'or' operator:
let level= player['level'] || 0

Very useful, thanks

Name of the music plz?

Great need more

My favorite way to use this is to return an empty dictionary for the default value. This way you can traverse huge nested dictionaries really easily. For instance, a school curriculum with Course, Section, Class Number that contains a list of required textbooks:

books = curriculum.get("DDSN", {}).get("101", {}).get("001", [])

This returns a list whether or not the class "DDSN 101-001" exists. With much more complex dictionaries this can be incredibly useful.

what is your theme name ?

Cool

This is dumb and ugly.
If you have anything more complex than just this, say 10-20 kv pairs, instead of assinging default values "at birth" you'll have to rely on idiotic defaulting which can cost you a lot of headache of "where tf this coming from".
This is one of reasons I quite hate python

Every short I find I put it in a good-to-know list. Great info!!

Nice! What theme do you use in VSCode?

Noice

This is one of the ones that I think I'll actually be using! Thank you!

Ayeee keep it up mang

If you want that default to be inserted into the dictionary instead, you could use a defaultdict
