You've Been Accessing Dictionaries Wrong! #python #programming #coding

This short shows you a better way of accessing Python dictionaries by using the .get() method.

Depends, defensive programming can be an anti-pattern. If the key should always exist, then you shouldn’t add defensive checks. You want your program to fail ASAP.

It depends on what you wanted to do but this gives a good alternative

Nice explanation for why not to use .get() on dictionaries. Thanks :)

This missing space before 0 kills me 💀

Literally working on a script with nested dictionaries right now, took a small break cause I got stuck, checked my notifications and found this. I think this might be a solution to the problem I’m facing, much appreciated 🙏🏻(I knew about this method, it just didn’t cross my mind)

[jadencorr]

It depends on the case, there is nothing like “never use get(key) or [key]”

Sometimes you even use pop(“key”) when you need to read the value and remove it from dictionary

[benjaminschaefer]

Adding on that, setDefault does the same as get, but it creates the key if it doesn’t exist

[praveens]

Error is always better than the default value

Hey thx I should add the get method way more, but my solution would be in a case where i now that there can be errors I would use a try, except, else command. But get is better.

[Mdroudian]

I use get... forgot about the 2nd parameter. Thanks for the reminder.

[gamingland]

if you expecting None in the value then u should use method one if not use second one

[jphvnet]

It depends the style/case. Don't use this as a rule.

[antoniopripizduchi]

Это по факту правильно, для этого и нужен метод get. А [] только для записи

[pontiffmaximus]

Your channel is just so useful, thank you!

[AbdulKareemAbdulRahman]

don't get it. surely th error is better?

[Robert-qwlr]

interesting, but I think I'd prefer to have it fail. Even if the subsequent code will work with a default value, if the code creating the dict did not create an item it was supposed to, then I want it to break.

[swims-in-money]

This kinda bothers me with most languages, many ways of doing the same thing, but of those options one choice is clearly better. I get that it’s due to languages getting better and maintaining compatibility, but still annoys me

[SohailAhmad-xktx]

I use this 'get' statement before watching this video...

[maximdegi]

avoiding errors is not making your program safe. better just to check if the key is dictionary (in most cases).

What is the name of that type of font?
