20 Everyday Tips & Tricks in Python

[@mateuszzebala]

"It's cool because there is Bob" 😂

[@יהבלזר]

really undurated!

[@cefarix]

Just wanted to point out that defining __ call __ on a class makes _instances_ of that class callable not the class itself. All classes are callable anyways since that's how you create new instances.

[@Владислав-м3е9г]

21:40 - I would use regex here, as instead of spaces there might be some other separations + upper case problem would be solved as well

[@aaronvegoda1907]

Yeah, 're' is amazing

[@DrDeuteron]

No 15: overloading repr() is a good idea. You can also use "type(self).__name__" or self.__class___.__name__ instead of the explicit "Person" in the f-string.

[@GOPINATH-jx1su]

2:59 Tip no 1:😅 No need to use number%2==0 there instead use number%2 only, because number%2 always gives you either 0 or 1,if 0 => False, if 1 => True😅❤ Note: change Even as Odd and Odd as Even😅😂 Good Teaching❤

[@lesheq85]

i can't believe you typed "odd" with zero instead of capital 'o'... this is bothering me...

[@rubenvanderark4960]

21:44 If you replace just " red" with " blue", the string " reduced" would still turn into " blueduced". Also, the string "red" would be unchanged because it doesn't start with a space.

[@mk00088]

In that case we can use *re.sub*

[@shittuto]

use " red " in that case. space before and after. with " blue " .

[@richardbennett4365]

What happens if one gets from the dictionary, "Bob" instead of getting "name?"

[@richardbennett4365]

print(*_) gives a space-delimited row of names, not a list object. 😮 Ha ha ha.

[@mudi2000a]

Regarding default values for dictionaries, you should also have a look at the collections.defaultdict class which I find very useful. There you can specify a general default value that you get if the key doesn't exist. This is very useful e.g. if you want to count something.

[@DavideCanton]

Another alternative is subclassing dict and defining the __missing__ method. It has the bonus of providing the key to compute the default dynamically

[@jeffreyphipps1507]

#13 "Bob, who's obviously named Jeff" - gets me every time... 🤣🤣🤣

[@laytonjr6601]

Using replace(' thing', ' other') doesn't work for words that start with thing (the same way replace('thing ', 'other ') doesn't work for words that end with thing (and if the character behind it is not a space, for exemple a period or a comma, it won't work either)

[@aaronvegoda1907]

Included with the python std lib there is a module called 're' that allows you to find and replace using regex

[@rokaskarabevicius]

Python is beautiful, but counter: Counter = Counter() is just not ZEN.

[@chrisdieguez1950]

I know, right? Get yer dang Java outta my Python

[@chrisdieguez1950]

I know right? Get yer dang Java outta my Python!

[@enksek]

what kind of syntax is this a: str="text" ? normally I just write a="text" never seen before in python.

[@Heavy_Lvy]

what i prefer in string multifaction is using an f string f'{'A'*20}H!'

[@cdm1972]

Lot of great tips in this vid. Probably will watch again later, lol.

[@richardbennett4365]

He wrote the numeral zero in the word "Odd" instead of the capital letter O. 😮

[@richardbennett4365]

If one wants to comvine two dicrionaries a and b, then why not simply a + b?

[@theorange6460]

I use these tricks everyday

[@syrupthesaiyanturtle]

23:50 you can also use a tuple as a key to achieve multilayer sorting such as min(names, key = lambda name: (name.lower().count('a'), name))

[@olfmombach260]

Very interesting, didn't think of that

[@wujublazedman6984]

33 sec ago was wild

[@rishiraj2548]

🎉

[@ChXXL]

Some tips really helped me. Thanks!

[@anon_y_mousse]

As a corollary to multiplying strings and arrays, I overloaded / so that I could divide them as well. Take for instance "ababab"/"ab" would yield 3, and "bababa"/3 would yield "ba". You could probably make a video on showing an implementation of that. It would likely be better than mine.

[@Muso-c8j]

what is the difference __str__ and __repr__

[@luketurner314]

11:15 for those in a country that swaps the decimal and comma in numbers: f'{big_number:_}'.replace('.', ',').replace('_', '.')

[@Chaminox]

damn actually useful

[@369Gamer]

Your content is very useful

[@alexcaffri9091]

aHHHhhaa (!)

[@vslabs-za]

Poor Bob, being byte by like 20 small pythons... sheez...

[@吳政霖-b9t]

13:21 ... it looks quite confusing. Haskell: Good luck!

[@JG-gy3tt]

Great video. My interest was peaked while watching.

[@christopheanfry2425]

Thank you for this very useful video. Can I ask you what theme you use in Pycharm?

[@novamc7945]

pretty sure he uses the default

[@loverboykimi]

This is Gold!

[@troshujin]

Yeah another indently vid! :D

[@arb6t9]

He made python more simpler

[@AfzalKhan-dp9zh]

splendid...keep up good work.

[@BobChess]

I love python

[@Anonymous-6598]

Great video

[@kumaranb8702]

Very nice 👍🙂

[@kamurashev]

Nice

[@Pawlo370]

Why you have adverbs if you have sponsored video?

[@Martin-delta]

What do you mean? “An adverb is a word or an expression that generally modifies a verb, adjective, another adverb”.

[@DrDeuteron]

@@Martin-deltayou’re kidding right? It’s too deadpan.

[@Martin-delta]

@@DrDeuteron lol no. I was genuinely confused. I just copied the Wikipedia entry for adverb. 🤷‍♀️

[@neuromorphing9933]

Lame... seen these "tips" 1_000_000 times before....

[@sridharhisaria]

i like the pun here
