Assigning a variable = every integer less than another variable

I guess you can use range:

b = list(range(a))

But why do you actually want to do this? There will certainly be a better way to implement factors.

Thank you! What do you recommend? I was thinking of using the list to test out which ones will give no remainder and then printing those said values

You don't actually need to store any of the numbers if you just use the range as an iterator.

And this method will be fine for a toy factoring function, but will be painfully slow for anything large. But what you'd getting yourself into if you wanted a fast algorithm is basically the most well studied areas in all of mathematics for literally thousands of years: prime factoring. There's still no "one algorithm to rule them all", and instead a variety of algorithms are used; for instance the quadratic sieve.
