Python Facts
——————

>>> two_wrongs = [False, False]
>>> bool(two_wrongs)
True

>>> bool(False + False)
False

The list is not empty
>>> bool([])
False
>>> bool([False, False])
True

Any non-empty object is considered True. Even if it's contains False booleans internally

>>> False + False == False
True

>>> bool("Nothing surprises me anymore")
True



Even one
>>> bool([False])
True


🚨 Little cautious when you are using Boolean in python!!!

Python tip

To update a list in-place, use a slice-assignment

t = s
......
s[:] = [f(x) for x in s if c(x)]

Now, both "s" and "t" reflect the new data.

"JavaScript is going to die soon, React is the last UI library you will learn, TypeScript is a bottle-neck, WASM is the way forward"

Companies in the real world: "We are looking for a jQuery developer, ES6 knowledge is beneficial".


Big war is going in Websdeveoper’s community !!

People have different opinions. Whatever UI/UX plays important role in every technology (Python / Java / .NET / Ruby / PHP)

Here are several ways to interactively display intermediate results during a calculation.

# Two liner
>>> q = 3.5 * 1.5
>>> q
5.25

# Second expression
>>> q = 3.5 * 1.5; q
5.25

# Walrus
>>> (q := 3.5 * 1.5)
5.25

# Invisible
>>> q = 3.5 * 1.5

For data preprocessing,pandas and pyjanitor python packages can be used

Guys,

Try this if you are free

In Python, memory is managed in a _______ space.

Can you fill your answer ?

A word on IEEE’s methodology: It pulls 300 programming languages from GitHub, then narrows that down to the 52 that earned the most search results in Google. Those 52 are then analyzed using 11 metrics, including data from Twitter, GitHub, and Stack Overflow, in order to arrive at IEEE’s aggregate score. Ok

Hi Everyone, let’s play some interesting and useful game here by tomorrow.

Port Numbers for different databases

Microsoft and NASA offer some ideas about how you could apply Python for space exploration.

Microsoft has teamed up with NASA to create three project-based learning modules that teach entry-level coders how to use the Python programming language and machine-learning algorithms to explore space, classify space rocks and predict weather and rocket-launch delays.


While Microsoft's NASA lesson doesn't offer any actual lessons in Python programming

Microsoft Offers Free Online Certificate Course in Artificial Intelligence for Students. December 14 to 19

Python runs fast on an Apple M1.

*****New type hinting in Python 3.9:


Lists, dictionaries are now annotated with the type directly (not by typing module), e.g.

numbers: list[float]

Python tip: Slice's are objects.

You can store them in variables or containers just as you would with a regular integer index.

>>> s = slice(6, 12)
>>> title = "Monty python's flying circus"
>>> title[s]
'python'

Use _ in python console to retrieve the result of the last statement

Today our DevSprint topic

The fastest way to build and share data apps for Datascience and Machine learning


Time 8PM IST


Note: this is not Django or Flask. But you thrilled to build great apps with no front end experience.

I will post link 3 hours before the session

2 hours 20 mins to go
