Python facts: OOP concept

super() can be used outside of a class definition.

>>> class A:
x = 10

>>> class B(A):
x = 12

>>> super(B, B).x
10

The super() call can't use the zero or one argument form because the class can't be deduced automatically from the context.

# Multiple Variable Assignment
a,b,*c=[1,2,3,4,5]
#print(a,b,c) ===> output : 1 2 [3, 4, 5]


#Swap two variables
a=1;b=5
a,b=b,a
#print(a,b) ===> output : 5 1


#Sum over every second element of a list
a=[1,2,3,4,5]
result=sum(a[1::2])
# print(result) ===> output : 6

Topic :
Commonly used python modules in realtime projects

Did you know?💡

The antigravity module originated in Google App Engine! Compared to the🐍Python 3's version it has a fly🦸‍♀️function that can even render the text of the comic in HTML.

The most popular Big Data tools are

Apache Spark,
Apache Kafka, and
Apache Hadoop/MapReduce, followed by Dask and Apache Hive.


We can also use these tools by python with different modules.

Here is the list of commonly used machine learning algorithms.
These algorithms can be applied to almost any data problem:

✅Linear Regression
✅Logistic Regression
✅Decision Tree
✅SVM
✅Naive Bayes
✅KNN
✅K-Means
✅Random Forest
✅Dimensionality Reduction Algorithms
✅Gradient Boosting algorithms
✔GBM
✔XGBoost
✔LightGBM
✔CatBoost

The overall market size for chatbots worldwide would be over $1.3B USD by 2024

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.
