Business as usual

I just finished reading Case in Point by Marc Consentino. It's a prep book for consulting case interviews, at firms like BCG and McKinsey. I picked it up because I'd like to better understand how corporate logic, the economy and the healthcare market affect me as a physician. I figured a book like this would be a good starting point, and contain advice on how to stay on top of business and finance topics.

One tool Consentino mentions, that I like, looks like this:

E(P=R-C)M

It's a tool used when analyzing the profits and losses of a company.

I've been on the lookout for a way to maintain my coding skills and simultaneously apply my maths knowledge. I found it!

projecteuler.net

Project Euler provides mathematical problems that require a computer and programming to be solved. For example, in order to even register for the site, one must solve the following problem:

A number is a perfect square, or a square number, if it is the square of a positive integer.

For example, 25 is a square number because 5^2=5 \times 5=25; it is also an odd square.

The first 5 square numbers are: 1,4,9,16,25, and the sum of the odd squares is 1+9+25=35.

Among the first 290 thousand square numbers, what is the sum of all the odd squares?

The Python Ternary Operator

My most recent Python dicovery is the ternary operator.

The ternary operator returns one of two values, based on the truthiness of a Boolean expression.

value_if_true if boolean_expression else value_if_false

Here's an example without the ternary operator, using an if-statement.

def odd_or_even(x):
    if x % 2:
        return "Odd"
    else:
        return "Even"

Here's the same function, using the ternary operator.
