python: dictionary to string, custom format?

Question

currently I\'m displaying keys only, each in new line:

\'
\'.join(mydict)

how do I display them like key:: value

Answer 1

Go through the dict.items() iterator that will yield a key, value tuple:

'
'.join(['%s:: %s' % (key, value) for (key, value) in d.items()])

Updated with modern f-string notation:

'
'.join([f'{key}:: {value}' for key, value in d.items()])
