10 Python Shortcuts You Need To Know

Welcome back to another video! In this video, I will be showing 10 useful python shortcuts! These won't be advanced shortcuts, just some python language features to save some time and lines of code. If you use python a fair amount, then this will definitely be worth your time.

Something that he left out about unpacking is that you could use * to group a section of your collection. Let's grab his example tup = (1, 2, 3, 4, 5), if we would unpack it as follow a, *b, c = tup, than a = 1, b = [2, 3, 4], c = 5

[Bassel-Ojjeh]

You are truly a legend Tim. I used to code when I was younger but lost my passion for it however now I am re-engaged to coding and your videos have been FANTASIC. Keep up the excellent quality of your teaching and videos.

Watch out when you multiply a nested list like that! All the sublists will be the same object, and changing one will change the rest

“The first thing you need to know is the sponsor of this video”, haha

[marcoreiser]

11:25, you probably wouldn't want to do this since it uses the original list's reference to duplicate it. If you make changes to one of the nested lists the other lists will also be changed. If you do x[0][0] = 2 for example, x is now [[2, 2, 3], [2, 2, 3], [2, 2, 3], ...] which is most likely not the desired behavior.

God bless you Tim! Thank you! From Nigeria

[Shepherd-ikqw]

EXTREMELY more helpful than I had expected !!! Thanks Tim !!

[DerMarkus]

That bit about For / Else was very insightful to me, specifically the fact that Else: ... only gets triggered if the For ... part has completed without a *break* . Thanks for this!

[marckiezeender]

fun fact: the "multiple assignment" syntax is actually the same as the unpacking syntax: the right side of the equation creates a tuple that is then unpacked by the left side. for instance: x, y = a, b creates a tuple (a, b) and then unpacks it into x, y

[erin]

Another cool thing combining multiple assignment, * and fstring:
tup = (1, 2, 3, 4, 5)
a, *b, _, c = tup
print(f"{a = }; {b = }; {c = }")
>>> a = 1; b = [2, 3]; c = 5

_ works as a variable (usually a throwaway one).

Who in their right mind gave this video thumbs down? It is brilliant. Thank you Tim you Python genius. I’ve learnt so much from your videos.

[uscjake]

Thanks Tim! I couldn't program at all 6 months ago, and with videos like yours it really helps make coding fast and productive.

[serg]

There is no name for the multiple assignment because there is no multiple assignment here, it is still a tuple unpacking:
x, y = 1, 2
is the same as:
x, y = (1, 2)
A tuple is defined by the commas, not the brackets. Brackets are optional in tuples and used just for readability, that's why a tuple with one element has to be declared as (1, ) and not (1).

[alexbadger]

Thank you for going over list comprehension. I was so confused on how to work them and their logic. You explained it so simply and beautifully

[maverick_augustine]

Just started learning python, your vids help me a lot.
Thx man !!!

[timwebster]

args and kwargs finally make sense! Thanks Tim

[paulah]

Very helpful video. Straight to the point. I watched it several times to make sure I remember each one. I am using all of them now including the bonus itertools. Thanks a lot Tim. 👍👍

[stephenaustin]

I've been following you for quite a while, but this is the first time I recognized from your accent that you're Canadian!

[dreamy-star]

'for & while else' and last bonus is pretty nice tips!!

[polojuninho]

That "bonus" one were very useful for me! Thx a lot!
