List comprehension and generator expressions - Intermediate Python Programming p.4

Welcome to part 4 of the intermediate Python programming tutorial series. In this part, we're going to talk about list comprehension and generators.

To begin, let's show a quick example and reason for both. A generator that is used commonly is Python 3's range() generator (Python 2's xrange).

this channel just doesn't get old.

Good to see instructors also make mistakes. That way, I get to think, I'll just practice more. Thanks.

[sunmakergg]

helpful guide. I'm going to google most of the stuff you type in because I need definitions of what they do otherwise they just fly waaay over my head.

[BrendanMetcalfe]

one of the better intro videos on generators

[cupajoesir]

i love that you leave in the errors. super helpful!

[ianrees]

Can't thank you enough for this intermediate series. Perfect for what I've learned since watching your beginner series. Love the new screen capture layout and everything. Also, I'm a composer so I'm curious about that speaker I see in the background. Do you have a full set up with a sub? Do you secretly blast EDM music at night?

This is a great video. I knew what generators were, and what list comprehensions were, but didn't realize how similar they were and the relative advantage of each.

If YouTube lets you highlight particular videos of your own, make this a 'Gold Star' or 'Blue Ribbon' one or whatever. It really is great.

keep pumping these out, very useful, thanks.

I ran: i = in python2 with 32GB of ram. My ram cried until python crashed.

[MrOnizukakira]

keep up !! thanks to sentdex i am getting better at python programming

[alan]

such a well demonstrated tutorial, thank you.

The parenthesis are a bit confusing, because I'm always associating those to tuples

[Tutoelectro]

Hi, I know this has nothing to do with python bu what keyboard do you use?

[neoXXquick]

Great video series.. thx for sharing..

[rrampaer]

Not python related but what do you record your screen/webcam with?
And as always, great video -- this series is exactly what I needed (stuck between 0 and hero)

For a moment, I thought that the computer was going to explode after the minute 4:54. XD

[farficknuger]

I believe in Python 2.7 you can use xrange() in order to get around the memory issue

[rotrose]

Thank you very much, this helps me a lot

[fabiogulmini]

What about
a = list(range(10))
Is it a generator or a list?

[dustbinsavesyou]

Now i dont understand it when i watch intermidiate python and when i watch basic python i start to think why the hell am i watching a totourial on what strings are
