My First Python Program

by levans, Jan 16, 2022, 9:50 PM

We have something of an oddity at AoPS. Our programming classes are in Python but we don't actually use Python. Instead we primarily use PHP and Node.JS for our back end programming. Because of this, I'm pretty proficient at those languages, but not many others. I used to be really good at Java and C/C++, but it's been so long that I've used them that it would take me a bit to get back up to speed on them, C/C++ especially. That being said, I wrote my first Python program on Friday! (Edit: Wow, I need to do some CSS adjustment! to make this look better.)

from collections import defaultdict
 
# Function to return a default
# values for keys that are not present
def def_value():
    return "Default"
 
# Defining the dict
d = defaultdict(def_value)
d["a"] = 1
d["b"] = 2
 
print(d["a"])
print(d["b"])
print(d["c"])

from collections import defaultdict

# Function to return a default
# values for keys that are not present
def def_value():
    return "Default"

# Defining the dict
d = defaultdict(def_value)
d["a"] = 1
d["b"] = 2

print(d["a"])
print(d["b"])
print(d["c"])

Yea so since python isn't exactly designed to run in the browser so I think aops uses skulpt for translating python to js calls, there are some terribly slow ways to actually run python in the browser. One is to emulate a full linux machine like on https://copy.sh/v86. Another way which may or may not be faster is to just implement linux syscalls like in https://webvm.io/ , or since the use case is narrowed down just to python you could just use a webassembly version of python like this one that comes up from google https://github.com/pyodide/pyodide, of course the current method is just a ton faster.
The one thing I miss from "real python" at the moment is the giant standard library or "batteries included" that python has but I'm guessing that support for these mostly depends on the upstream open-source project.
