Learning Python

@frogandtoad 

I dont know why I didnt look it up!

Guido van Rossum wanted to give his programming language a name that was unique, mysterious and short, and what better than naming it Python after Monty Python's Flying Circus.

I was (am) a big Monty python fan but it was a bit arbitrary  choosing to call it so.

At least I learned something new today, ha, ha.🤣

Monty?

42?

Struggling otherwise!

PS

have you noticed that even the most innocuous of post spawn into long threads?

Indeed... Monty python was behind the naming of python... and we love it's meaning of life of 42 😉

Hi @ronbentley1,

   Python was apparently chosen by Python's creator from "Monty Python's Flying Circus" ... a UK based iconic comedy program/troupe dating back to 1969, originally a short tv series, but since responsible for a few films, touring show, etc.  .. e.g."Naming" section in

https://en.wikipedia.org/wiki/Python_(programming_language)

'42' comes from Hitchhiker's Guide to the Galaxy by Douglas Adams ... another Brit, originally a radio play series, but since converted to a book, tv series and a (*****) film

Best wishes, Dave

I'm a big fan of the monty 😉

@davee , @frogandtoad

Yep, I am old enough to have watched both series when they first aired!

We Brits know to to write anorak comedy!🤣

I'll be dipped!  I read this... and thought, miss-print? joke? I had to Google it!  

It'd really be nice if they also made it like a ?: operator.  Now that I'd use!  Maybe in #21. Something like:

const char*   altitude <=> 0 ? "USAF auguered in!" : "Army has lead in their shoes" : "Naval Aviator with the gods";

We are seriously RIPPED OFF here in AUS, taxed to the F&^%^EN eyeballs!

This is not meant to be inflammatory, it's just my ignorance asking to be enlightened.  I have to admit that I don't know the politics behind Australia's current state of affairs.  From what I gather someone down-under told China to go pound-sand and China has gotten all huffy.  Just wondering if you ignore the pain of the taxes, do they have a fundamental high-ground ethics reason behind them?  The few things I hear about Australian policies seemed more like common sense and things I'd wish our country would do.  BUT, what little I've read is not from a common Australian citizen.

Go for it, post away, I am sure you will start a good series of debates and queries.

We are here to be enlightened!!

Only joking, but you clearly have a passion here and it would be great if you might share it to provide an opportunity for members to develop their understanding and skills.

If we are not prepared to learn, then what's the point!? We owe it to ourselves to explore and develop.

Looking for to new challenges

Regards

Thanks Ron!

Indeed... I am passionate about programming, and I truly love to teach people, and not just about programming, that's why I am here!

I am no where near the best, but I do love to interact, debate and challenge the narrative to explore and arrive to the best outcomes for all in sundry... that's me in a nutshell 😉

I will think of something to post, that relates to such discussion and thoughts!

Cheers

Ok, I just thought of a very basic example, based on a recent post no less, from @barrie thread: (Writing a timing function).

From my understanding, the goal was to recreate a [delay function], with the difference that it did not block all CPU execution as per the default delay function does (please do correct me if I am wrong!).

With that in mind... I will plagiarise (and slightly modify @inq working code), to show off some of the power of C++, with respect to scope and naming conflicts/symbols within the language.

namespace barry {
  
    bool delay(u32 interval) {

      static u32 lastTime = millis();
      u32 currentTime = millis();

      if (currentTime - lastTime >= interval) {
        return lastTime = currentTime;
       }

      return false;
     }
 }

void setup() {
  Serial.begin(9600); 
 }

void loop() {
   // useage...
   if(barry::delay(1000)) {
     Serial.println("executing...");
    }
 }

...namespaces are cool, when you want to use the same library name ('delay') for your own library without conflict!

FYI: namespaces have been around since C++11

Cheers

It's no joke 🙂 - The C++ language has vastly improved over the years - the C++23 ISO standard is not far away, and will offer even greater functionality!

It struck me some time ago that when someone adds the ESP8266/ESP32 functionality, that they've totally replaced the compilers (under the covers) maybe to gcc or something like it.  Not sure... since I don't use any Arduino hardware anymore.  I've found on a few occasions when I suggest something on the forum, they report back that it doesn't work for them and sure enough if I switch to an Uno and compile... it pukes.  It's almost like Arduino (the company) wrote their own compiler for their boards. 

True that!

We are in 2022, and as far as I'm concerned... Arduino UNO* is dead!
ESP8266 / ESP32 are IMHO, the current defaults in terms of power and language compatibility.

If you need something *significantly* faster, then look into Teensy 😉

The truth is that your country, mine and a few others are controlled by the same ar^#%(*)es (WEF, UN, WHO), and we need to eradicate them before they eradicate us!

I will never let these bastards rule the people if I can help it, and I will do my best to stop them!  Some people are not awake, but I really hope they wake up quickly, before it's too late for all of us!

Keep fighting these bastards!

Cheers

Nothing I can do about it so I just don't think about it.

I can't comment any further without getting political and would be off topic for these forums.
