Still stuck on those practice problems…
(for reference right now I’m trying to figure out how to only output all the even numbers of a numpy array)
I now know what % does! It takes the remainder, or ‘modulo’, of a number. For instance 5%2 = 0.5. The function itself is also called a modulo (or sometimes string formatting in rare contexts). I learned this from this article/video.
A little frustration:
When reopening Jupyter notebooks I’m finding my computer doesn’t remember any of the variables I’ve defined, and that I need to run all the code again. So how does one run all of the code at once? Rather than go through each command box individually.
I’m still confused on:
Formatting!!! I know conceptually that I should be able to run a code that says if the value in an array %2 == 0, then print(value), else don’t print… but I’m running into all sorts of errors that I believe are just me not know how to properly type something. Right now my code looks like:
for i in arrfloat.any():
if i%2 == 0:
(arrfloat is the name of the array)
I don’t completely know what “i” is doing there but that’s what someone in a tutorial put. I will likely find the answer in this video... but don’t have the time to because I’m in school and it’s finals season so I’ve got to go do school work
I shall return to you soon… and demystify these challenging formatting problems.
Love you Aman.
