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.

- 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]
(11 / 24)
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".

This is a beginner's guide on mining cryptocurrencies.
🧵 👇🏻
Mining 101
Typically, when you transfer money using a service like Paypal, they take a small cut for facilitating the exchange.
In cryptocurrencies, people like you and me act as Paypal and facilitate exchanges of cryptocurrency. We get a cut for this just like Paypal did.
In order to make these transactions happen, our computers need to do some calculations which requires a lot of computational power.
A GPU or a Graphics Processing Unit which is typically marketed for gaming workloads can be used to mine cryptocurrencies.
Why do you need a GPU?
Today, there are so many miners that the "difficulty" of mining cryptocurrencies has skyrocketed, which basically means it takes a lot of computational power to mine crypto which GPUs can provide and CPUs cannot.
(❗ This is an oversimplification)
If you are interested in the inner workings of how blockchain and cryptocurrency, then I highly suggest that you read this thread by @oliverjumpertz

What actually is a Blockchain?
— Oliver Jumpertz (@oliverjumpertz) February 16, 2021
Bitcoin is breaking record after record, but there must be more to the technology than just crypto, or not? Well, we can take a look at the underlying technology first to understand what it actually provides to us.

The 12 most important pieces of information and concepts I wish I knew about equity, as a software engineer.
A thread.
1. Equity is something Big Tech and high-growth companies award to software engineers at all levels. The more senior you are, the bigger the ratio can be:
2. Vesting, cliffs, refreshers, and sign-on clawbacks.
If you get awarded equity, you'll want to understand vesting and cliffs. A 1-year cliff is pretty common in most places that award equity.
Read more in this blog post I wrote: https://t.co/WxQ9pQh2mY
3. Stock options / ESOPs.
The most common form of equity compensation at early-stage startups that are high-growth.
And there are *so* many pitfalls you'll want to be aware of. You need to do your research on this: I can't do justice in a tweet.
https://t.co/cudLn3ngqi
4. RSUs (Restricted Stock Units)
A common form of equity compensation for publicly traded companies and Big Tech. One of the easier types of equity to understand: https://t.co/a5xU1H9IHP
5. Double-trigger RSUs. Typically RSUs for pre-IPO companies. I got these at Uber.
6. ESPP: a (typically) amazing employee perk at publicly traded companies. There's always risk, but this plan can typically offer good upsides.
7. Phantom shares. An interesting setup similar to RSUs... but you don't own stocks. Not frequent, but e.g. Adyen goes with this plan.
