This is a step-by-step guide on getting started with Python as a total beginner.
(includes free resources and everything else you need to get started)

Don't expect to make AAA games or state of the art machine learning models in a week.

With all that being said, let's dive straight in.

Linux and macOS users can skip this step because they come pre-installed with Python.

Make sure to Add python to path by checking this option 👇

We'll be installing VS-Code, one of the best code editors out there and it's free!

- Printing statements
- Variables
- Operators
- Conditions
- Functions
- Loops
Let's take a closer look.

You can 'print' or output in Python using the print() function.
print('Hello World') will give you an output of `Hello World`
(10 / 24)
These store certain values that can change.
For example, You can declare a variable 'x' with a certain value.
x = 9 [Here 9 is assigned to varaiable x]
y = 'Hello World' ['Hello World' is assigned to y]
x = 8 [x has been updated to a new value which is 8]

These carry out arithmetic operations in Python
+ : Addition
- : Subtraction
* : Multiplication
/ : Divide
% : Modulus (Remainder after dividing)
** : Exponents
(12 / 24)
They look like this 👇
a = 33
b = 200
if b > a:
print("b is greater than a")
else:
pass
Think of it as telling Python to do something based on conditions: if this is true, do this; else do something different.
(13 / 24)
These are basically blocks of code that can be run when you call them. This helps us write code more efficiently.
In Python, you can make functions using the def keyword.
def myFunction():
print("Hello")
myFunction()
(14 / 24)
These essentially run a piece of code over and over again until a certain condition is met.
There are 2 types of loops in Python:
- While loops
- For loops
Let's take a look at them.
(15 / 24)
i = 1
while i < 6: //While i is less than 6
print(i) // do
i += 1 //this
The output is :

fruits = ["apple", "banana", "cherry"]
for fruit in fruits:
print(x)
The output:
(17 / 24)
'fruit' is the above loop is a temporary variable. It gets a value from the list called 'fruits' starting from "apple" then to "banana" and then "cherry".

I have even more threads for further steps in Python coming up, stay tuned.

This course on Traversy Media's channel is a great next step for taking your python skills to the next level!

This is probably the most underrated resource for learning python.

A common misunderstanding about Agile and “Big Design Up Front”:
There’s nothing in the Agile Manifesto or Principles that states you should never have any idea what you’re trying to build.
You’re allowed to think about a desired outcome from the beginning.
It’s not Big Design Up Front if you do in-depth research to understand the user’s problem.
It’s not BDUF if you spend detailed time learning who needs this thing and why they need it.
It’s not BDUF if you help every team member know what success looks like.
Agile is about reducing risk.
It’s not Agile if you increase risk by starting your sprints with complete ignorance.
It’s not Agile if you don’t research.
Don’t make the mistake of shutting down critical understanding by labeling it Bg Design Up Front.
It would be a mistake to assume this research should only be done by designers and researchers.
Product management and developers also need to be out with the team, conducting the research.
Shared Understanding is the key objective
Big Design Up Front is a thing to avoid.
Defining all the functionality before coding is BDUF.
Drawing every screen and every pixel is BDUF.
Promising functionality (or delivery dates) to customers before development starts is BDUF.
These things shouldn’t happen in Agile.

I\u2019d recommend that the devs participate directly in the research.

If the devs go into the first sprint with a thorough understanding of the user\u2019s problems, they are far more likely to solve it well.

What an amazing presentation! Loved how @ravidharamshi77 brilliantly started off with global macros & capital markets, and then gradually migrated to Indian equities, summing up his thesis for a bull market case!
@MadhusudanKela @VQIndia @sameervq
My key learnings: ⬇️⬇️⬇️
First, the BEAR case:
1. Bitcoin has surpassed all the bubbles of the last 45 years in extent that includes Gold, Nikkei, dotcom bubble.
2. Cyclically adjusted PE ratio for S&P 500 almost at 1929 (The Great Depression) peaks, at highest levels except the dotcom crisis in 2000.
3. World market cap to GDP ratio presently at 124% vs last 5 years average of 92% & last 10 years average of 85%.
US market cap to GDP nearing 200%.
4. Bitcoin (as an asset class) has moved to the 3rd place in terms of price gains in preceding 3 years before peak (900%); 1st was Tulip bubble in 17th century (rising 2200%).

Bubble or Bull Market? Join us for a short presentation and candid one on one on 27th Jan, 4pm with Shri \u2066@MadhusudanKela\u2069. \u2066@VQIndia\u2069 \u2066@sameervq\u2069 #bubbleorbullmarket pic.twitter.com/LBvlBrz6mS
