I am starting with Oops in python today.
Drop some tips!!!

Recently, while learning Python, I discovered some subtle points that have changed the way I view Python:
1) Reference: Unlike other programming languages, Python variables are not containers that hold a value. Instead, Python variables are pointers that refer to an object.
A mind-blowing example to understand why this matters:
a = [1,2,3]
b = a
a.append (4) #This returns None btw
print(a,b)
Many people might think that after this, a = [1, 2, 3, 4] while b remains [1,2,3], but that's exactly why we should learn more about references.
In reality, both variables point to the same object in memory; thus, both will be the same list object with the same elements.
2) Mutability & Immutability: In Python, mutability and immutability are crucial concepts. While references are a big part of this discussion, using the same example for strings helps to clarify this concept even better.
a = "1, 2, 3"
b = a
b= b. replace ("1", "2")
print(a,b)
The result here will differ!
While a will remain "1,2,3 ", but b will become "2, 2, 3" because "strings are immutable!"
This is significant because any operation on an immutable object creates a new object. Therefore, when a method is performed on b, b will refer to a new object.
3) list methods: Do you know that some list methods return new objects?
If you want a new list, you can concatenate lists or copy a list using the. copy () method. These techniques help create new lists, which can be very useful.
4) Python & its objects: Everything in Python is an object. From functions to modules to generators, everything is an object. This means their names should follow the same rules as variable names, and you can pass them into other functions or your main function as needed.
5) Scopes: When you assign a variable in Python and print that variable, Python does something very interesting.
Example:
x = 10 #global
def name():
x = 12 #enclosing
def name _ 2 ():
x = 13 #local
name_2()
name()
Here, Python first checks for a local variable (inside the inner function), then for an enclosing variable (inside the outer function), then for a global variable (outside the functions), and finally for built- in variables.
Now, Python will surprise you with a tricky moment!
If you write:
x = 12
def n():
Print (x)
x = 10
It will return an error!
Because Python checks for local variables first, it is printing x before assigning a value to X.
I hope reading this tweet would give you some aha moments!!!

Well, people on Twitter have always supported me and celebrated every milestone with me.
Not a very big gesture, but if you're not verified, drop a comment below.

the stuff i have to do for 2 social internship credits 😭
> 1 month internship with an NGO
> go to a school and talk about AI and Career Options
> do a 15 hour course on social work
> maintain a logbook and prepare a report
a very different summer than what i had planned

WTF, I just realized one of my favorite YouTubers cleared the UPSC and became an IAS officer. Bro going to do public service now.

@mihir_twt japanese and chinese are very tough , spanish won't give you any edge
English
and i also need to pick a language from
> Chinese
> French
> German
> Japanese
> Spanish
im leaning towards german or chinese/japanese

writing 2 different posts so i can get better advice. i have to select one open elective course this year in additon to mandatory core courses. > Computer-Aided 3d Geometric Modeling > Device Materials > Electrical Installation & Practices > Geo-Informatics > International Standards > Microcontrollers and Interfacing > Production Process & Metrology > Sensors and Actuators > Numerical Methods i want a general idea about these courses before i make a selection, not looking to just score for cgpa

@QOSMIC__Space is building laser-based communication for satellites.
Which can transmit data 100X faster than traditional RF systems.
And do this at fraction of the cost.
They've already tested this entire system across a 10 km link on Earth.
Their system basically has two critical infrastructures.
First is Argus - which is an optical ground station designed to track satellites with extreme precision and receive the laser signals carrying their data.
Second is Zaphod - which is simply a tiny device that transmits data through a precisely aimed laser beam.
Now, the only problem with laser-based communications is the weather.
If there are clouds between the ground station and satellites - it can disrupt communication.
But they have a simple solution to this problem.
They can just spread out their ground stations at multiple locations. So if their are clouds over one region, the satellite can simply beam the data to another ground station.
Btw Starlink uses the same technology to provide internet speeds of up to 200 Gbps.
This is the same technology that we'll need to build at scale when we start building orbital data centers in space.
And this is exactly what @Jain_Shrey_ and his team at Qosmic Space are trying to do.
Shrey Jain@Jain_Shrey_
We've raised $3.33 Million to build the Optical highway to the Cosmos. Led by @AccelIndia and @Prosus_Ventures and given foundational and early support by @southpkcommons, @artparkindia and Manish Jain. Space is going from an endeavor to an economy. The world is racing to build the satellites of tomorrow, but still using the infrastructure of yesterday to talk to them. At @QOSMIC__Space our goal is to fundamentally solve this problem from an infrastructural lens, and build the backbone of communication for humanity's final frontier. A decade ago this company gets built in the US or Europe. We built it in Bangalore. All three of us left careers abroad to come back, because India now has the capital, the manufacturing depth, and the institutions to build world-class space infrastructure. We came back because this is now the right place to build it, and we will not be the last founders to make that choice. Building this with @RohitKR79 and @aalokelab . We are just getting started. Onwards and Upwards. @ACCEL @spc_india @prateekmehta42 @ankitcc @adityaag @akhi_agarwal @nayankote @_pagarwal @artparkindia @iiscbangalore @JPBrebner
