Some of us were looking for a place to start off our Machine Learning and Data Science Journey.

I have some resources that can help you! 😁

Check them outπŸ‘‡πŸ‘‡
1. 100 Days of Code by Ayon Roy
This repository is a gold mine for someone who is looking to begin ML. It explains to you how to go about every little topic.

Link: https://bit .ly/3wtWFwx
2. Kaggle Courses
Another phenomenal source to get started with Data Science and Machine Learning. It has topic-wise courses that can up-skill you.

Link: https://www.kaggle .com/learn
3. StatQuest
To clarify basic statistics concepts along with machine learning concepts, you can definitely hop here. It would clear your fundamentals on micro & macro topics of ML and statistics.

Statistics Playlist: https://bit .ly/2UB59EK
ML Playlist: https://bit .ly/2VzOh1F
To clear up SQL basics and extras, you can definitely check out:- https://bit .ly/2Vt5gTb

w3schools has amazing tutorials for SQL -> https://www.w3schools .com/sql/default.Asp
The topics you should cover for different roles in Data Science according to your interest and what specialization suits you is listed in the following link:-

https://bit .ly/3e8I4js
🌟 There is no guarantee that a paid course will provide you with all the knowledge. So, don't rely on them.
1. Study the topics you should know
2. Watch YouTube or Udemy tutorials
3. Practice the topics (Projects)
4. Repeat
FYI, the links are working. There is a space between the links because the Twitter algorithm messes when you provide tweets with other links.
You just copy the link and paste it & remove the space. It will work fine!
There might be some issues with the links. So here:-

Do you know about the SLICING technique that helps you work around strings in Python??

To handle sub-strings, you can use the SLICING method.
πŸ‘‡πŸ‘‡
Let's say we have a string.

a = "This is a string."

You can slice between the string!

πŸ‘‰ a[start_index : end_index : stride]

Terms:-
start_index -> Takes an integer value; this is the index value (inclusive) from where you want to start slicing.
end_index -> Takes an integer value; this is the index value (exclusive) where you want the slicing to end.

stride -> Takes an integer value; indicates how many characters to skip after the first character is retrieved.

Note: The first character index is always 0.

The topic of TRIGGERS is a level-up from creating queries and sub-queries in the handling databases.

A super-easy guide to triggers in SQL πŸ§΅πŸ‘‡
β˜‘οΈ What is a trigger in the laymen (standard) language?

When someone pokes you or does something to agitate you, there is a high chance that you might get 'triggered' automatically! Right?
β˜‘οΈ Triggers in SQL

So, when we say TRIGGERS in SQL, it is simply a stored program that gets executed on its own when a triggering event occurs. Now, triggers are a part of PL/SQL.

PL/SQL is an extension of SQL where SQL queries are used and procedural statements/language.

STRINGS - Handling them like a PRO! 😎

Some in-built functions that can make your task of working around strings a cakewalk!

Thread 🧡
β˜‘οΈ What are STRINGS?
In Python, there is no character! Even a single character is considered a string. Strings are an immutable sequence.

Immutable -> Once strings are created, they cannot be changed.
So, you can't change the string, but the reference to it can be changed.
β˜‘οΈ .split()
a = "this is a string"
a.split()

O/P: ['this', 'is', 'a', 'string']

The string is split into each word in the sentence, considering the DELIMITER as space. The output of the split function is given in a LIST.

What else can I say about SQL to prove that it is crucial to know how to work around databases?

Having said that, SQL could be the one thing that you could begin your programming journey with. 🀩

A Beginner-friendly version of SQL (UPDATE and DELETE)
πŸ§΅πŸ‘‡
🌟 Let's look at the table first!
The name of the table is -> faculties
We have columns as FacultyId, Name, Class, EmailId and Salary. "Faculties" Table.
β˜‘οΈ UPDATE
This clause is used to change values in a specified column.
You may or may not provide a condition along with the change you want to make.

πŸ‘‰ Update without condition:-
UPDATE table_name SET column_name = column_value;

I hope you are practising SQL whilst you are learning it. This technique makes it easier to understand concepts.

Alrighty, here is another thread for SQL. 🀩

🌟Which table are we working on today?
The name of the table is "products". So the columns that we have are productCode, productName, productDescription, among others.

Take a look πŸ‘‡ Column namesOverview of the information in the columns
β˜‘οΈ IN
This clause would reduce the efforts to write multiple OR conditions. It helps you find a specific match for a value.

πŸ‘‰ select column1, column2 from table_name where EXPRESSION IN ('value1', 'value2')
