Search - "kwargs"

Python tip: some python functions have **kwarts (key-word) arguments, that means you can construct your parameter dictionary like so:
kwargs = { 'a':1, 'b':2}
And pass those arguments like so:
function(**kwargs)8 -
Python is a fucking joke. "Readability" disguised as 150+ magic methods and values. Virtual environments to hide shitty dependency management. Strings that may or may not act as comments. No correlation between package and module names - install Pillow; import PIL. **kwargs instead of options=dict(), because why separate function arguments from arbitrary extra data? And finally, the only way to have tkinter on Windows is to install IDLE, so that some fucktard can stick their shitty app right up yours ...7

I got my dirty fingers on this leak of an AMAZING ML model capable of pondering EVERY PARAMETER IN THE UNIVERSE and saying if your business idea needs improvement or is good to go.
BEHOLD THIS 100% PURE PYTHON SOLUTION:
```python
import random
def magic(*args, **kwargs):
if random.random() > 0.5:
return "Good to go!"
else:
return "Requires improvement on value proposition"
```
This LEAK is from a startup that just received 4 BILLION USD IN VENTURE CAPITAL to improve their AI SYSTEMS.
Literally enough money to solve world hunger forever.

Python devs and data analysts....
Do you recommend using pycharm for working with jupyter notebooks? I surely had a bad time with it.
I have been using many jetbrains softwares , and am a fan of their docs search and autocompletion. But I don't think there is a full support for jupyter jn it, because sometimes my graphs made using matploit or seaborn just brakes.
And some libraries have a lot of functions taking parameters as " *args, **kwargs " , I don't know what that means but those function take a lot of "value" parameters i guess?(like this: plt.figure(figsize=[13,6], axis=False) )
Pycharm also don't seem to have access to list of those arguments...
Are you having such problems too? Have you found some better ide with autocompletions and support for jupyter? Do tell.
(Ps: i know jupyter can be run directly on a browser, but as i said "auto completions and documentations" )5 -
Call me late to the party, but the concept of kwargs really helps keep a lot of redundancy and related mistakes to a minimum.1
