I share a #Python tip every Wednesday in the @PythonMorsels newsletter. Recent tips included:. • avoiding complex string joins via print.• making more user-friendly classes.• making whitespace-sensitive multiline strings. Subscribe for a weekly tip 💌.

New video on the 3 ways to check your operating system in #Python. os‍.name is the least granular. sys.platform has well-documented values. platform.system() is the a runtime check (the others check the OS it was built for, not the one it's running on).

There's not always a one-to-one relationship between high-level operations and individual dunder methods. Read more 👉 #Python.

"Just as creating a function can give a name to an otherwise unnamed block of code, sometimes there's also an opportunity to create a new variable to clarify code." #Python.

So the mapping part of this comprehension has an "inline if" within it. Read more 👉 #Python.

Comments can be great, but try to avoid using them when a docstring, a better function name, a better variable name, or a new variable or function might be better. Read the full article: Avoid over-commenting in Python.▸ #Python.

Do you ever forget how to format a number like 1,234.50 in #Python?. Forget the weird f-string syntax for zero-padding and space-padding strings?. Me too. Over the weekend, I made a tool to help: Paste an example string to see the format spec you need.

I just added to my Python quick resource bookmarks list. I also realized it can act as a Python docs URL shortener: All my #Python quick resource bookmarks: Thanks @y2mango!.

If we have two lists and we wanted to know whether the items in these two lists are the same, we could use the equality operator (==). Read more 👉 #Python.

Dunder methods essentially act as a sort of "hook", allowing us (Python programmers) to customize the behavior of built-in Python behaviors. Read more 👉 #Python.

In the 1960s, teleprinters used a carriage return (CR) to move the printhead back to the beginning of the line, and they used a line feed (LF) to move to the next line. Read more 👉 #Python

Loops that involve early break conditions can often be rewritten to use a helper utility that does the early break work for you, but not always (and sometimes it doesn't make them more readable). Read more 👉 #Python.

New screencast on startswith/endswith & removeprefix/removesuffix in #Python. Don't use slicing or the various strip methods when there's a better way to check for (and remove) prefixes/suffixes.

Whenever I see a dunder method called within code, I think "something low-level is going on here". #Python.

Unlike, JavaScript, C, Java, and many other programming languages we don't have traditional C-style for loops. Read more 👉 #Python.

My weekly office hour session is starting in 4 hours: Not sure when to use a class? Not understanding something about decorators? Have another #Python pondering?. Join me!

To compare the items in a list with the items in a tuple, we could convert the list to a tuple or the tuple to a list, and then check for equality. Read more 👉 #Python.

In Python, we love duck typing, which means we often care about the behavior of an object more than the type of that object. Read more 👉 #Python.

Need some #Python help?. I'm holding an office hour session tomorrow @ 4pm US/Pacific Time. Join here for free:

So we can use any(), all(), or Python's "in" operator to check conditions. but what if we need to get the actual value that matches rather than just a boolean indicating whether there was a match? #Python.

Need a lookup table in #Python?. You need a dictionary!.
