Straightforward Python Q for anyone who fancies a look

Thanks for talking through it with me, have a good lunch.

What makes you say it's broken?

and have -1 represent no join

if distance_matrix[vertex_1[vertex_2]] != -1:

My code is super wrong

if distance_matrix[vertex_1[vertex_2]]:

So to check if they are connected - having a distance != 0:

That would make a very nice structure

Ah, I hadn't thought about nesting dicts

@Peilonrayz I think I will go for a nested lists. It would be cleaner than messing around with dictionary.keys() and zip. Many thanks for your help

This is what makes me question the benefits of a dictionary

But I already keep a list of vertices in the code, so I wouldn't be running d.keys()

I said enumerate but that would be incorrect, I think I need to use zip

I will probably post it for review once I have mangled some code together

Thank you for letting me work through the problem, I think I have a solution

{"A":[0,3],"B": [3,0]}

well, chars but I think Python doesn't distinguish

Strings

The keys would be the vertices

If I had a dictionary I could store the distances (weights) and then enumerate with the keys. I would require another list for that if I went with the 2d

I want to implement a distance matrix, but I don't which structure to use. I could use a 2d array or a Python dictionary.

Okay, thank you.

Can I ask a short question here? Not a review, but for general Python advice.

@IvenBach Hello

Hi

* not my image

Most of them fit, however, I intend to bend one row of pins to fit

@W5VO Sorry, but I don't understand

The longer side measures 0.5cm

That would solve the soldering issues, however, would that be long enough to connect to the female pins on the other board?

Any help would would be much appreciated

I cannot figure out a way to solder them with the stripboard in the desired orientation and not melting the plastic in the process

I have a stripboard and some male headers. I want to DIY a shield for my Uno. The headers are difficult to solder as I would prefer to have the non-copper side upwards, this means the plastic section of the header is touching the stripboard and I cannot reach the copper tracks to solder.

I am wondering how to solder headers to a stripboard

would this be the right SE site for a question regarding soldering techniques?

Or should I open another thread w.r.t. the 20%?

So in answer to the second part of my query: is 'the 20% of black respondents answered positively' too convoluted to state as a fact?
