Numbered list in python

问题

I need to make a numbered list from list elements in python. Example list:

destinations = ['Los Angeles ', 'Rhodos ', 'Dubai ', 'Manila ', 'Mallorca ', 'New York ']

I need to print out elements as numbered list:

1. Los Angeles 
2. Rhodos 
3. Dubai 
4. Manila 
5. Mallorca 
6. New York

If I do:

print ('\n'.join(destinations)) 

It prints out elements on separate lines, but I cannot add numbers.

回答1:

You simply use enumerate() and count from 1

>>> destinations = ['Los Angeles ', 'Rhodos ', 'Dubai ', 'Manila ', 'Mallorca ', 'New York ']  
>>> for index, value in enumerate(destinations, 1):
...     print("{}. {}".format(index, value))
... 
1. Los Angeles 
2. Rhodos 
3. Dubai 
4. Manila 
5. Mallorca 
6. New York

for i, dest in enumerate(destinations, 1):
    print(" %d. %s" % (i, dest))
