I'm surprised nobody is protesting inequality in higher education. Students of prestigious universities have long had access to superior teaching and resources. Thereby increasing inequality between those who are admitted to these schools and those who are not.

@@whipit2404 I mean that's just reality, the parents of the students probably worked really hard to where they are now so they could provide a world-class education for their kids. Nothing to protest here, not getting into Harvard doesn't mean the end of the world but you can hope to either work harder then others to get in yourself or work hard so that your kids get into Harvard.

Amazingly concise overview of the usefulness of flask and exactly what I was looking for. I thought it was a missed opportunity in the video to mention that list comprehension is done in C rather than for loops which are native python, making loops embedded in list comprehension orders of magnitude faster than regular for loops.

1:30:20 The instructor said that you cannot indent in a list comprehension (only use a list-comprehension when it fits within the screen). This is not true. Since the list comprehension is wrapped within a pair of brackets [ ], you can break the line anywhere you prefer to facilitate enhanced readability; and the list comprehension will work perfectly fine. Although, a really long list-comprehension that requires one to break down into multiple lines, may not be desirable, as future maintenance of such code could elicit unnecessary confusion. One of the tenets of writing better code is also the how less cryptic it is for future maintenance. Also, request.args.get("q") is getting called as many times as the number of words in WORDS variable. Perhaps a more resource-conserved approach will be this: q = request.args.get("q") words = [ word for word in WORDS if word.startswith(q) ]

At 1:30:15 I'd emphasize a list comprehension may be spread out over several lines for readability i.e. it doesn't literally have to all be on one line. Indenting within the square brackets won't matter to Python, but the reader might appreciate the added whitespace.

Html first, then Css, then javascript, then frameworks, libraries, API's...I would find good resources so you can go deeper on each one. Get some web developer bootcamp Udemy courses for example which also provide a structured path. Just advice from someone who started this journey 3 years ago and now I work doing this : )
