Why is this the only thing pyfags have? And they're not even that good at it.
It is a meme, just like the academic lispfags that never really got anything done but were supposed to be the new holy grail of scientific/academic computing were a meme. Python will always be a beginner language that a programmer should at one point grow out of.

UI libraries don't add anything new, graphical libraries seem to be under utilized, Perl is better for system admin scripts in my opinion, python needs extra security precautions. Not good for high performance tasks. not easibly portable, Still python is one hell of a swiss army knife because of the community.

It means you're shit at analogies son
>>54498348
This is a terrible comparison.
Owning a truck yourself is faster, but you have to be licensed, you have to own a truck, you have to insure the truck, you have to maintain the truck, you have to fuel the truck. This costs time and money.
Or I can just toss some guy some cash and not have to worry about any of that. Sure it may arrive a day later than if i had my own truck, but my life was made easier. I can also do other things while some other schmuck is driving the furniture for me.
It's still a flawed analogy, but in the end, if all I'm trying to do is crunch some raw data to create some human readable charts, is performance really the metric I give a shit about?

Multi-threading is terrible anyway. Cooperative scheduling with co-routines is where's it's at (call it "green threads" or however you want).
If you need more performance:
1) Don't use CPython
2) Don't use CPython
3) Spawn multiple processes and have them communicate

>>54497197
I love Python but it's weakness is where C/C++ take over and vice versa.
When you program in python what you're actually doing is programming a programming language to program a programming language to program a computer. This can be called progprogprogramming, and just as three lefts make a right, three progs make an amateur linguistic twiddler.
>>54497197
Arguments against python being the best language in the world:
It's slow
It has quirks
No/whacky dynamic memory allocation
Easily replaceable, unlikely to be used that much 20 years from now
Seems to leave little legacy code, so if a better alternative shows up, python will disappear quickly (Compare with perl)
However:
It's easy to learn
It's fast to type
It's widespread
It has plenty of nice libraries for plenty of different things
It's multi-paradigm
Of course all languages have different applications. In its own category python is probably one of the best languages that you could learn. And given that most programming should be done (cycles are cheap, programmers expensive) in high-level languages python is probably one of the best languages to learn all categories as well.
>>54498904
Vim with Jedi
>>54497412
Python was like my 5th programming language and I still use it all the time for simple programs and scripts. There are plenty of applications where it really is a good tool for the job.
There is no single programming language that is suited to every task. If language X has some useful libraries and features that would make your project easier, then use that instead of being autistic. Language evangelists are so annoying, and most of them have never done any real-world programming outside of their mom's basement.

There aren't any sane people who swear by Python 2, it's just because of legacy code or libraries that are in 2 and not supported in 3 so you stick with what you have.

In the language itself? Pythondef foo():

You use it in Python you dolt. You've heard of an API? The standard library of many languages were not fully implemented through the language itself most of the time. It makes no difference if it's another library, you are programming in Python

Off yourself.
Every CS major I have ever seen start you off with Java. It's fucking bullshit. I major is Cyber Security and I had to take two programming classes plus a cryptography class that required coding in Java (Dropped that shit fast). I didn't even know what coding was coming into college so I struggled with it. Bad experience with it overall.

I got by those classes by just looking up code and using debug mode to learn how the code worked. I did write my own code, but that was off of looking at code I did in class with the teacher. lol The way it is taught is a joke and the language they choose is pretty questionable IMO.
Im going to be learning Python and JS this summer. Looking forward to it. Giving coding a second chance.

Classes are just objects like strings, dummy. Would you put a string inside a function?def foo():

x = 10
foo = type('foo', (), {})
def setter(value):
nonlocal x
x = value
foo.set = setter
foo.get = lambda: x
return foo
x = foo()
assert x.get() == 10
x.set(20)
assert x.get() == 20
