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 ‘‘
