#Python tip: Learn to spot and fix quadratic behavior whenever data inputs can get large:

Slow:

combined = list1 + list2 + list3 + list4 + list5

Faster:

combined = list(chain(list1, list2, list3, list4, list5))

Score one for the itertools module.

Common problem! Here are some useful tips to better as for help as a developer:

[Bob Belderbos @bbelderbos]

`functools.partial()` lets you put a wrapper around an existing function (it “freezes” some portion of a function’s arguments and/or keywords)

To illustrate this we make our own print() function defaulting the `end` keyword to a comma (regular print's default = newline)

🎙️ I sat down with @jhodapp the other day to discuss:

• The benefits of #coaching, also for #developers

• The effectiveness of (real-world) projects-based learning

• How soft skills / #mindset really matter

Not many people leave reviews (I understand that since I rarely do myself–I need to change this habit), but those who did all left ★★★★★ reviews

@s_gruppetta_ct An outstanding book, highly recommended. I use the first chapter in class as a gentle introduction to their first Python program for my freshmen students. They appreciate it. Kudos and thanks to Stephen.

My 12th #Python book is now on Kickstarter! This time I am writing about Python Logging

You'll learn everything you need to know about this topic. I'll also introduce you to a couple of other Python logging packages

[Gijs Mos @gjmos]

@driscollis Just finished the book. All you need to know about standard Python logging and more. In Mike's easy-to-follow style. Lots of examples in the book and from the accompanying Github repo. I have learned some new tricks like the built-in log rotation and many more. Thanks Mike."

@driscollis Reading it now...

My latest #Python book is here!

@s_gruppetta_ct @draftacenter @Xowap Also tried zipfile (it is in the standard library) on my result, but it makes it bigger. Also tried it on a bytes object with 2 bytes per number. No luck either.

Finally, I used a slightly bigger end value in the randint, but that makes no difference.

[Gijs Mos @gjmos]

@s_gruppetta_ct @draftacenter @Xowap As list[int]: sys.getsizeof(numbers)=8448728, len(numbers)=1000000
As packed bytearray: sys.getsizeof(bin_nrs)=1172121, len(bin_nrs)=1125000
As packed bytes: sys.getsizeof(bin_nrs)=1125033, len(bin_nrs)=1125000

@s_gruppetta_ct @draftacenter @Xowap We have 1M positive integers between 0 and 300. Each such integer would fit in 9 bits. By packing these 9 bit numbers in a bytes or bytearray object of 8 bit bytes you would need 1M * 9 / 8 = 1_125_000 bytes. Ex overhead I get:
