[FIXED] How to add labels to nodes in a CIRCULAR GRAPH with networkx in python

Issue

I'm drawing a circular graph using the method:

nx.draw_circular(G, node_color='b', edge_color='#909090', node_size=500)

Basically what I want to do is to add labels to the nodes but I don't find the way to add them in this type of graphs. I tried using:

nx.draw_networkx_labels(G,labels=labels,pos=nx.spring_layout(G),font_size=16)

but there is a problem with the position layout, it is not next/in each node.

Solution

Solved!

G=nx.Graph()
G.add_nodes_from(range(20))
e = [(0,1),(0,2)]
G.add_edges_from(e)

# some labels
labels={}

nx.draw_circular(G, node_color='y', edge_color='#909090', node_size=500,labels=labels)

plt.axis('equal')

[FIXED] Woocommerce: remove all form labels at once

Issue

I'm using WooCommerce to build a webshop.

The determined format for forms is that there's no labels, only placeholders. I've been removing the labels like so:

<?php

// WooCommerce Checkout Fields Hook
add_filter( 'woocommerce_checkout_fields' , 'custom_wc_checkout_fields' );

// Change the format of fields with type, label, placeholder, class, required, clear, label_class, options
function custom_wc_checkout_fields( $fields ) {

//BILLING
$fields['billing']['billing_first_name']['label'] = false;

return $fields;
}
?>

But since I want no labels anywhere, I was wondering if there's a way to remove all of them at once. Instead of going through them all individually. Does anybody have an idea?

Thanks!

EDIT:

I realize this is possible by just adding some css(display none), but since this is not a very clean solution, I was wondering if there is some other way to accomplish this.

Solution

You can remove any $field->property with unset.
Good reading and references can be found here: Customizing checkout fields using actions and filters

Now, for your question in how to do it globally, you can use a loop, something like:

// WooCommerce Checkout Fields Hook
add_filter('woocommerce_checkout_fields','custom_wc_checkout_fields_no_label');

// Our hooked in function - $fields is passed via the filter!
// Action: remove label from $fields
function custom_wc_checkout_fields_no_label($fields) {
    // loop by category
    foreach ($fields as $category => $value) {
        // loop by fields
        foreach ($value as $field => $property) {
            // remove label property
            unset($fields[$category][$field]['label']);
        }
    }
     return $fields;
}
