Doug is such an oddly charismatic guy.

[andyalberts]

I always look forward to Dougie Fresh's shorts vids. David is a raging madman, slinging information at top speed. Dougie pulls it all in and makes it more digestible (No shade to David, the whole team is a great combo)

Update to code at 16:53: now you can use f-strings too:
print(f"In {year}, {prez} took office.")

[nervous]

It's somehow uncomfortable when seeing variable type not

[rautermann]

2019 UPDATE: Dictionaries entries stay in the order you created them - in CURRENT VERSIONS of Python (3.7 and above)!

And for all of us who got so used to explicitly declaring variable and return types: It's worth mentioning that using types explicitly is possible now in Python (through special syntax) and I feel it's becoming more common at the moment! It is totally optional, but it can be useful to avoid errors from wrong types!

For some reason i like C more than Python. I really enjoyed the first 5 weeks actually.

[pyb.]

Hi, just a quick note on the fact that using "id" as a parameter variable in the object is not ideal as id() is actually a built in function in Python. Using "id_" or "iden" or whatever will resolve the issue that most students will encounter when trying to print jane.id.

[sungvin]

That explanation with __init__ has finally cleared all of my previous questions, such a nice entry to the OOP

[qixiangwong]

Like most of your intro videos, except the OOP explanation in this one. If someone doesn't know OOP from other language, your explanation in this one probably just exploded their heads

[arunkumaralagarsamy]

this syntax is simple for 16:58 print(f"In {year}, {pres} took office")

[femtoapple]

perfect python crash course. thanks Doug!

[DogginsFroggins]

Pythons greatest asset is its coolness

C - a literal letter, lame
Java - Coffee is boring
Java Script - Cooler because script sounds leet
Assembly - Reminds me of highschool.
Python - An actual snake


Python is the winner

[gamingbeasts]

Doug you are awesome...incredibly awesome..

[scaramouche]

Python looks like a paragraph that is missing periods between sentences at first glance lol. I got used to brackets and curly braces.

[montheist_tv]

16:19 how does the know what "prez" and "year" is? How does it know to correspond to the tuple values?

[dzmespm]

This 39-minute video, one of the most useful "shorts" in the world, calls itself a "shorts"

[banj]

22:55 Should be updated that Python 3.7 onwards dicts will preserve insert order. Maybe write it on the video's description, because it could potentially confuse future students.

[MoolsDogTwoOfficial]

Since I coded a lot in Python since 2019 to 2023, this week will be a breeze.

nums[len(nums):] = [5]
Could anyone tell why the hell there is that colon after len(nums)?
