1、Given: an array containing hashes of names

Return: a string formatted as a list of names separated by commas except for the last two names, which should be separated by an ampersand.

Example:

namelist([ {‘name‘: ‘Bart‘}, {‘name‘: ‘Lisa‘}, {‘name‘: ‘Maggie‘} ])# returns ‘Bart, Lisa & Maggie‘namelist([ {‘name‘: ‘Bart‘}, {‘name‘: ‘Lisa‘} ])# returns ‘Bart & Lisa‘namelist([ {‘name‘: ‘Bart‘} ])# returns ‘Bart‘namelist([])# returns ‘‘

Best Practices:

def namelist(names):    if len(names) > 1:        return ‘{} & {}‘.format(‘, ‘.join(name[‘name‘] for name in names[:-1]),                                 names[-1][‘name‘])    elif names:        return names[0][‘name‘]    else:        return ‘‘

My solutions:

def namelist(names):    #your code here    if len(names) > 1:        first_name = ‘, ‘.join(tmp_name[‘name‘] for tmp_name in names[:-1])        last_name = names[-1][‘name‘]        print(first_name)        print(last_name)        return first_name + ‘ & ‘ + last_name    elif names:        return names[0][‘name‘]    else:        return ‘‘
