Who's Monty & what's a White Room got to do with *truly* understanding concepts in #Python #coding?

What’s more challenging in the early days when you learn coding is to join the dots between various topics you learn, viewing them as a coherent set of tools

#100daysofcode Image
Here's The White Room analogy in brief:

I call the computer program Monty.

Monty is the one who’s busy doing things, performing all the actions required in your computer program.
But Monty/the computer program needs some infrastructure to be able to operate.

This infrastructure is the White Room: an empty room with white walls and white ceilings–a blank canvas.

How to Make Small Multiple Charts in Python, with Plotly


#datascience #datavisualization #Python #pythonlearning
Remember: small multiple charts break out a visualization by a categorical variable.

We take a simple chart and break it out into panels.

#Datavisualization #datascience
There are a variety of tools to make small multiple charts in Python, including the Seaborn FacetGrid technique.

In Python ...

You can combine Numpy arrays vertically or horizontally using np.concatenate

#Python #pythoncode #datascience
The first argument to the function is a list (or collection) of arrays that you want to combine.

You can actually combine many arrays ...just put them inside the list.
The axis parameter controls the direction along which you combine the arrays.

For 2D arrays ...

'axis = 0' combines vertically
'axis = 1' combines horizontally

In Python, you can visualize images with the Plotly IMshow function.


#Python #pythonlearning #datascience #datavisualization

You can use Plotly IMshow for a few uses.

You can use it to plot heatmaps ...

But you can also use it to plot images.

The syntax for Plotly IMshow is pretty simple.

You call the function as px.imshow and then provide the name of the image file you want to visualize.

(This assumes you've imported Plotly express as px)

In Python ...

You can use the Pandas dropna method to drop rows with missing values.

#Python #pythoncode #datascience ImageImageImageImage
As seen above, you can limit dropna to specific columns with the 'subset=' parameter.

With 'subset=', you can specify the columns in which dropna will look for missing values

#Python #pythonlearning #datascience
If it finds missing values in any of those columns, it will drop the row.

But it will ignore missing values in other columns.

In Python ...

You can use Numpy all to test conditions about the properties of a Numpy array.

#Python #pythoncode #datascience ImageImageImageImage

So for instance, in the example above, I test if all of the values are greater than 2, by column.

To do this, you need to know how np.all works ...

But you also need to know how to use axes.

Our topic of today is a "PRINT FUNCTION" in python.

#SSOT #PYTHON #pythonlearning #Python #pythonprogramming #CyberSecurity #softwaredevelopment
In Python, the command print tells the program to display words or numbers on the screen. Here's a line of code that tells Python to display the words “Hello, World!”

print("Hello, World!")
print is a keyword—that is, a word that has special meaning for Python. It means, "Display what’s inside the parentheses." Note that print isn't capitalized. If you capitalize it, the program won’t run.

Today we are going to talk about "DATA TYPES IN PYTHON"
Just follow the thread till the end.

#pythonprogramming #pythonlearning #SSOT #python
What is data type in python programming?

In python programming, a data type is an attribute of data which tells the compiler or interpreter how the programmer intends to use the data.
In python programming, data type is an important concept.

Variables can store data of different types, and different types can do different things.

Python has the following data types built-in by default, in these categories:

Find the median and the quarts parts of a statistic sequence in #pythonprogramming: a thread
1/ First write an median function which find the half indice of a list using n = len(list) (lenght of list) means (n-1)/2 if n is odd and between n/2 - 1 and n/2 if n is even.
In this function, we particularly use % for design arithmetic rest and int operator to convert float to integer. NB: we suppose that at the beginning, list is range by increase order.
2/ Afterwards we define a new function using same logic, but in more take an list of notes,
create a new list knowing that value of first list list[i] design students number who have been the note i. And send the median of the new list.

Hi Reader, I hope you are having a good day and will have a great life from now on.

Day 8 of #100DaysOfCode.

Type 2 of itertools
remember you have to import them using
from itertools import name_of_itertool
Take values from iterable while the predicate function remains true,once predicate function returns false it will no
longer take values.
lis_even=list(takewhile(lambda x:x % 2 == 0,lis))
returns lis_even=[2,4]
Returns a running total of values in iterable.
returns lis_new=[0,1,3,6]

Good morning to you all. Just a quick note to let you know that I am the 67th Pythonista who cracked Bite 317. Pickling objects - on behalf of @pybites I Challenge You! #Python #CodeChallenges
With almost every challenge, I learn something new. This time how to load (deserialize) and dump (serialize) a data structure from/to a pickle file which supports storing your own objects.
Needless to say, this requires additional practice to fully understand and apply independently.
But that's the whole idea behind learning something new and making it your own.

#Learn 🧠🐍#python: Sometimes when programming in python they're situations when you want to copy the contents of an existing list into another. Python has several ways of achieving that. In this thread you will learn different ways of achieving that with the help of examples. Image
1) Using the equal (=) sign operator:
Using = operator you can copy the contents of an existing list onto another/new list. But there's a problem with this method which I will explain on the next section. Image
The problem with the above method is that if you modify the new copied_fruits list the original list (fruits) is modified too, this is because the copied list (copied_fruits) is referencing/ pointing to same fruits list in memory.

Hi Reader, I hope you are having a good day and will have a great life from now on.

Day 7 of #100DaysOfCode.

1)Recursive Functions:
Every recursive function has a base case that stops it from going into the fourth dimension(that's what I like to think 😅).
Example 1: Image
Recursive functions can be implemented with more than one function. Here's an example for checking even and odd numbers
Example 2: Image

If you've a bit of Python experience, yu know exactly what yu want, & its a fairly standard web application that involves displaying some content, storing some stuff in a database, having users register, & having administrators b able to control what's on the website: use Django.
If you are a Python beginner: use Flask.
