Identify Stocks on Reddit with SpaCy (NER in Python)

Reddit has been at the epicenter of one of the biggest movements in the world of finance, and although it seemed like an unlikely source of such a movement — it’s hardly surprising in hindsight.

The trading-focused subreddits of Reddit are the backdrop for a huge amount of discussion about what is happening in the markets — so it is only logical to tap into this huge data source.

When building a data extraction tool like this, one of the first things we need to do is identify what the data we’re extracting is actually about — and for that we will be using named entity recognition (NER).

Once we have our data we need to process it and extract organization names so that any further analysis is automatically classified and results assigned to the correct stocks.

Organizations are mentioned in each subreddit in a variety of formats. Typically we will find two formats:

Organization name, eg Tesla/Tesla Motors
Ticker symbol, eg TSLA, tsla, or $TSLA

We also need to be able to differentiate between tickers and other abbreviations/slang —some of these are unclear like AI (AI can mean both artificial intelligence and refer to the ticker symbol for C3.ai).

So, we need a reasonable competent NER process to accurately classify our data.

Lambda, Map, Filter functions in python

Welcome to my Blog, In this article, we will learn python lambda function, Map function, and filter function.

Lambda function in python: Lambda is a one line anonymous function and lambda takes any number of arguments but can only have one expression and python lambda syntax is

Syntax: x = lambda arguments : expression

Now i will show you some python lambda function examples:

Python NULL - How to identify null values in Python?

Let’s understand what does Python null mean and what is the NONE type. In many programming languages, ‘null‘ is used to denote an empty variable, or a pointer that points to nothing. ‘null’ basically equals 0. Whereas in Python, there is no ‘null’ keyword available. Instead, ‘None‘ is used, which is an object, for this purpose.

Python Tricks Every Developer Should Know

Python is awesome, it’s one of the easiest languages with simple and intuitive syntax but wait, have you ever thought that there might ways to write your python code simpler?

In this tutorial, you’re going to learn a variety of Python tricks that you can use to write your Python code in a more readable and efficient way like a pro.

Let’s get started

Swapping value in Python

Instead of creating a temporary variable to hold the value of the one while swapping, you can do this instead

>>> FirstName = "kalebu"
>>> LastName = "Jordan"
>>> FirstName, LastName = LastName, FirstName 
>>> print(FirstName, LastName)
('Jordan', 'kalebu')

How to Remove all Duplicate Files on your Drive via Python

Today you’re going to learn how to use Python programming in a way that can ultimately save a lot of space on your drive by removing all the duplicates.

Intro

In many situations you may find yourself having duplicates files on your disk and but when it comes to tracking and checking them manually it can tedious.

Heres a solution

Instead of tracking throughout your disk to see if there is a duplicate, you can automate the process using coding, by writing a program to recursively track through the disk and remove all the found duplicates and that’s what this article is about.

But How do we do it?

If we were to read the whole file and then compare it to the rest of the files recursively through the given directory it will take a very long time, then how do we do it?

The answer is hashing, with hashing can generate a given string of letters and numbers which act as the identity of a given file and if we find any other file with the same identity we gonna delete it.

There’s a variety of hashing algorithms out there such as

• md5
• sha1
• sha224, sha256, sha384 and sha512
