Therefore instead of accessing each element of each list, we use an iterative approach. The below example code demonstrates how to find the cartesian product in Python using the iterative method. defget_cart_prd(pools):result=[[]]forpoolinpools:result=[x+[y]forxinresultforyinpool]returnresult...

How do you realize ℂ as a Cartesian product of two sets? Consider how complex numbers are multiplied; by grouping real and imaginary parts, show how the pattern of complex multiplication can be used to define multiplication in ℝ×ℝ. Using this multiplication, find the multiplicative ...
So far we've looked at how generate_series() works and how you can use functions to add additional dynamic content to the output. But how do we quickly get to the scale of tens of millions of rows (or more)? This is where the concept of a Cartesian product comes into play with...

This short post is about how to write something like×i∈IViand×i∈IVi MathJax doesn't allow picture environments so we can't define a new command that draws a cross. The solution is simple: Enlarge the normal \times command. Paste this in a math environment at the top of the documen...
If you collected lists of techniques for doing great work in a lot of different fields, what would the intersection look like? I decided to find out by making it. Partly my goal was to create a guide that could be used by someone working in any field. But I was also curious about th...
